An abnormal hemoglobin resulting from the substitution of valine for glutamic acid at position 6 of the beta chain of the globin moiety. The heterozygous state results in sickle cell trait, the homozygous in sickle cell anemia.
A commonly occurring abnormal hemoglobin in which lysine replaces a glutamic acid residue at the sixth position of the beta chains. It results in reduced plasticity of erythrocytes.
A compound formed by the combination of hemoglobin and oxygen. It is a complex in which the oxygen is bound directly to the iron without causing a change from the ferrous to the ferric state.
Minor hemoglobin components of human erythrocytes designated A1a, A1b, and A1c. Hemoglobin A1c is most important since its sugar moiety is glucose covalently bound to the terminal amino acid of the beta chain. Since normal glycohemoglobin concentrations exclude marked blood glucose fluctuations over the preceding three to four weeks, the concentration of glycosylated hemoglobin A is a more reliable index of the blood sugar average over a long period of time.

Coupling of the oxygen-linked interaction energy for inositol hexakisphosphate and bezafibrate binding to human HbA0. (1/606)

The energetics of signal propagation between different functional domains (i.e. the binding sites for O2, inositol hexakisphospate (IHP), and bezafibrate (BZF)) of human HbA0 was analyzed at different heme ligation states and through the use of a stable, partially heme ligated intermediate. Present data allow three main conclusions to be drawn, and namely: (i) IHP and BZF enhance each others binding as the oxygenation proceeds, the coupling free energy going from close to zero in the deoxy state to -3.4 kJ/mol in the oxygenated form; (ii) the simultaneous presence of IHP and BZF stabilizes the hemoglobin T quaternary structure at very low O2 pressures, but as oxygenation proceeds it does not impair the transition toward the R structure, which indeed occurs also under these conditions; (iii) under room air pressure (i.e. pO2 = 150 torr), IHP and BZF together induce the formation of an asymmetric dioxygenated hemoglobin tetramer, whose features appear reminiscent of those suggested for transition state species (i.e. T- and R-like tertiary conformation(s) within a quaternary R-like structure).  (+info)

Altered ligand rebinding kinetics due to distal-side effects in hemoglobin chico (Lysbeta66(E10) --> thr). (2/606)

Hb Chico is an unusual human hemoglobin variant that has lowered oxygen affinity, but unaltered cooperativity and anion sensitivity. Previous studies showed these features to be associated with distal-side heme pocket alterations that confer increased structural rigidity on the molecule and that increase water content in the beta-chain heme pocket. We report here that the extent of nanosecond geminate rebinding of oxygen to the variant and its isolated beta-chains is appreciably decreased. Structural alterations in this variant decrease its oxygen recombination rates without significantly altering rates of migration out of the heme pocket. Data analysis indicates that one or more barriers that impede rebinding of oxygen from docking sites in the heme pocket are increased, with less consequence for CO rebinding. Resonance Raman spectra show no significant alterations in spectral regions sensitive to interactions between the heme iron and the proximal histidine residue, confirming that the functional differences in the variant are due to distal-side heme pocket alterations. These effects are discussed in the context of a schematic representation of heme pocket wells and barriers that could aid the design of novel hemoglobins with altered ligand affinity without loss of the normal allosteric responses that facilitate unloading of oxygen to respiring tissues.  (+info)

Sickle hemoglobin polymer melting in high concentration phosphate buffer. (3/606)

Sickle cell hemoglobin (HbS) prepared in argon-saturated 1.8 M phosphate buffer was rapidly mixed with carbon monoxide (CO)-saturated buffer. The binding of CO to the sickle hemoglobin and the simultaneous melting of the hemoglobin polymers were monitored by transmission spectroscopy (optical absorption and turbidity). Changes in the absorption profile were interpreted as resulting from CO binding to deoxy-HbS while reduced scattering (turbidity) was attributed to melting (depolymerization) of the HbS polymer phase. Analysis of the data provides insight into the mechanism and kinetics of sickle hemoglobin polymer melting. Conversion of normal deoxygenated, adult hemoglobin (HbA) in high concentration phosphate buffer to the HbA-CO adduct was characterized by an average rate of 83 s-1. Under the same conditions, conversion of deoxy-HbS in the polymer phase to the HbS-CO adduct in the solution phase is characterized by an average rate of 5.8 s-1 via an intermediate species that grows in with a 36 s-1 rate. Spectral analysis of the intermediate species suggests that a significant amount of CO may bind to the polymer phase before the polymer melts.  (+info)

Physiological effects of modified hemoglobin as an oxygen-carrying macromolecule. (4/606)

A stabilized hemoglobin as oxygen-carrying macromolecules was developed. It had approximately 90,000 dalton molecular weights and its intravascular half life was 36 hours. Its molecular size was less than 0.1 micron. Its hemoglobin concentration was 6% and P50 value was 24 mmHg. The oxygen carried inside the plasma performs differently than the oxygen carried inside the red cells. Only less than 0.3 ml of oxygen in 100 ml of blood is available inside the plasma while 14-19 ml of oxygen is carried inside the red cells. Thus, less than 5 ml of oxygen is available inside the plasma of the entire body. When a patient develops hypovolemic shock, the red cells are bypassed and are not perfused directly inside the tissues. However, the plasma should reach such hypoxic tissues. Thus, infusion of oxygen-carrying macromolecules in the plasma should be therapeutically effective even if less than 100 ml of stabilized hemoglobin solution were infused under shock conditions. The basic physiology of oxygen-carrying macromolecules is described in detail, which is different from the oxygen carried inside the red cells.  (+info)

Metal complexes as allosteric effectors of human hemoglobin: an NMR study of the interaction of the gadolinium(III) bis(m-boroxyphenylamide)diethylenetriaminepentaacetic acid complex with human oxygenated and deoxygenated hemoglobin. (5/606)

The boronic functionalities on the outer surface of the Gd(III) bis(m-boroxyphenylamide)DTPA complex (Gd(III)L) enable it to bind to fructosamine residues of oxygenated glycated human adult hemoglobin. The formation of the macromolecular adduct can be assessed by NMR spectroscopy via observation of the enhancement of the solvent water proton relaxation rate. Unexpectedly, a strong binding interaction was also observed for the oxygenated unglycated human adult hemoglobin, eventually displaying a much higher relaxation enhancement. From relaxation rate measurements it was found that two Gd(III)L complexes interact with one hemoglobin tetramer (KD = 1.0 x 10(-5) M and 4.6 x 10(-4) M, respectively), whereas no interaction has been observed with monomeric hemoproteins. A markedly higher affinity of the Gd(III)L complex has been observed for oxygenated and aquo-met human adult hemoglobin derivatives with respect to the corresponding deoxy derivative. Upon binding, a net change in the quaternary structure of hemoglobin has been assessed by monitoring the changes in the high-resolution 1H-NMR spectrum of the protein as well as in the Soret absorption band. On the basis of these observations and the 11B NMR results obtained with the diamagnetic La(III)L complex, we suggest that the interaction between the lanthanide complex and deoxygenated, oxygenated, and aquo-met derivatives of human adult hemoglobin takes place at the 2, 3-diphosphoglycerate (DPG) binding site, through the formation of N-->B coordinative bonds at His143beta and His2beta residues of different beta-chains. The stronger binding to the oxygenated form is then responsible for a shift of the allosteric equilibrium toward the high-affinity R-state. Accordingly, Gd(III)L affinity for oxygenated human fetal hemoglobin (lacking His143beta) is significantly lower than that observed for the unglycated human adult tetramer.  (+info)

Fetal hemoglobin (HbF) synthesis in baboons, Papio cynocephalus. Analysis of fetal and adult hemoglobin synthesis during fetal development. (6/606)

Fetal hemoglobin (HbF) and adult hemoglobin (HbA) synthesis was studied in fetal baboons, Papio cynocephalus, to determine the normal pattern of hemoglobin production during fetal development. Fetuses ranging from 53 to 180 days gestation (term gestation 184 days) were used. Erythroid cells were incubated with 3H-L-leucine, and the rates of globin chain synthesis and the distribution of radioactivity into hemoglobin intermediates and completed hemoglobin molecules were determined. Gamma chain synthesis accounted for approximately 97% of the total nonalpha chain synthesis up to 140 days gestation; beta chain synthesis accounted for the remainder. After 140 days gestation, approximately equal quantities of gamma and beta chain were synthesized in the bone marrow. Prior to 140 days gestation, total alpha chain synthesis was 30% greater than total non-alpha chain synthesis, while there was balanced chain synthesis after 140 days gestation. During the period of excess alpha chain synthesis, fetal erythrocytes contained a large pool of alpha-hemoglobin (alpha chain with heme attached) molecules uncombined with beta or gamma chains. In view of the possibility that alpha chains may have a lower affinity for gamma chains than beta chains, excess alpha chain synthesis may be required to maintain low levels of free gamma chains.  (+info)

Kinetic studies on the binding affinity of human hemoglobin for the 4th carbon monoxide molecule, L4. (7/606)

L4, the affinity of hemoglobin for the 4th CO molecule, has been determined for human adult hemoglobin (HbA) as a function of pH and the presence of organic phosphates by measuring the kinetic parameters for the reaction. l'4, the rate of combination of CO with the triliganded molecule, was measured by flash photolysis while l4, the rate of CO dissociation for the ligand-saturated molecule, was measured by ligand replacement. L4 is pH-dependent and affected by 2,3-diphosphoglycerate. Additionally, this pH dependence of the high affinity state is largely eliminated by carboxypeptidase A digestion. L4 for human fetal hemoglobin (HbF) in phosphate buffers was also determined and found to be pH-dependent. These results cannot be reconciled within the framework of the two-state allosteric model. Additional structures in the conformational equilibrium due to either intermediates in the T to R transition or two or more R states must exist.  (+info)

Iron nutritional status in preterm infants fed formulas fortified with iron. (8/606)

AIMS: To prospectively evaluate the iron nutritional status of preterm infants fed either a term (0.5 mg/dl iron) or preterm (0.9 mg/dl) formulas fortified with iron after hospital discharge. METHODS: Healthy low birthweight preterm infants were randomly assigned into three groups at the time of hospital discharge. Group A were fed an iron fortified preterm formula (0.9 mg/dl iron) until 6 months corrected age; group B, a fortified term formula (0.5 mg/l iron) until 6 months corrected age group C, the preterm formula between hospital discharge and term, then the term formula until 6 months corrected age. RESULTS: Seventy eight infants were followed up to 6 months corrected age. Iron intake from formula differed significantly between the groups (A, 1.17 mg/kg/day (SD 0.32) > C, 0. 86 mg/kg/day (SD 0.40) = B, 0.81 mg/kg/day (SD 0.23); p < 0.0001). Haemoglobin concentrations were similar to those of iron sufficient preterm infants of the same postnatal age, and term infants of the same postmenstrual age (after 3 months of age). There were no significant differences in haemoglobin concentration (p = 0.391), plasma ferritin (A vs B, p = 0.322), or in the incidence of iron deficiency (A vs B, p = 0.534). CONCLUSIONS: Iron fortified formulas containing between 0.5 and 0.9 mg/dl iron seem to meet the iron nutritional needs of preterm infants after hospital discharge.  (+info)

Abstract: A simple ketoamine 14C-fructosoglycine with all the fructose carbon atoms labelled was synthesized for studies of possible pathways of the ketoamines metabolism in animal body. The ketoamine bond in the fructosoglycine was not hydrolyzed during incubation with homogenates of rabbit liver, kidney, spleen and testicular tissues within 3 hrs at pH 4.8 and 7.3 as well as after hydrolysis with pancreatine (the enzymatic extract from bovine pancreas) at pH 8.4. 14C-fructosoglycine administered into rabbit circulation was mainly excreted with urine (about 70% of the label) within 8-14 days. The main part of the ketoamine was excreted as fructosoglycine and the lower amount--as glycated dipeptide; some amount of fructosoglycine was hydrolyzed liberating fructose or converted into aldimine which was hydrolyzed with formation of glucose. The ketoamine was metabolized also into non-reducing isosucrose-like glucofructoside, insensitive to acid and enzymatic hydrolysis ...
Hemoglobin: The new conversion factor we use is 0.1551, instead of 0.6205. The new factor gives the conversion of hemoglobin tetramer mass concentration into SI unit (mmol/l). The molecular weight of the hemoglobin tetramer, including the heme groups, is 64,458 g/mol (approximately 4 x 16,000). With a normal hemoglobin concentration of 15 g/dl, the concentration in mmol/l is 2.327. Thus, the conversion factor yields 0.1551 given by 2.327 divided by 15. Note that 4 x 0.1551 is 0.6205, the conversion factor to convert g/dl into the concentration of hemoglobin monomers, not tetramers ...

TY - JOUR. T1 - Reductive hydroxyethylation of hemoglobin A. Functional properties of hemoglobin A selectively hydroxyethylated or dihydroxypropylated at the α-amino groups. AU - Acharya, A. S.. AU - Sussman, L. G.. PY - 1983/12/1. Y1 - 1983/12/1. N2 - The reactivity of the amino groups of hemoglobin A toward reductive hydroxyethylation with glycolaldehyde in the presence of NaCNBH3 has been investigated. The α-amino groups of the α- and β-chains of hemoglobin A are the most reactive amino groups of the protein for reductive hydroxyethylation; both sites are about equally reactive. Similarly, on reaction of hemoglobin A with glyceraldehyde in the presence of NaCNBH3, the α-amino groups of both the α- and β-chains of the protein undergo selective reductive dihydroxypropylation. Modification of the α-amino groups of hemoglobin A either by reductive hydroxyethylation or reductive dihydroxypropylation apparently lowers the pK(α) of the α-amino groups and results in an early elution of the ...

Obviously, during pregnancy, the entire volume of blood increases significantly, which is one of the primary reasons for the reduction in hemoglobin and the concentration of red blood cells in the body. This process also includes a triggering mechanism for the development of anemia.. A high level of hemoglobin usually suggests that there are too many erythrocytes in the blood. The medical concept is erythrocytosis. This process causes a number of concomitant complications, because it can disrupt blood circulation and lead to its unregulated clotting.. It is very important to have a normal level of hemoglobin just before the pregnancy itself, during the whole period, and naturally after the birth. Regular check of the level of hemoglobin is very important to ensure that the proper level of hemoglobin remains stable.. In the case of anemia, as one of the ways to treat a low level of hemoglobin, the doctor can prescribe iron-containing drugs and special supplements to bring the level to ...

  • Hemoglobin is a protein in red blood cells that carries oxygen. (
  • High hemoglobin level is most often caused by low oxygen levels in the blood (hypoxia), present over a long period of time. (
  • Haemoglobin combines with oxygen , enabling blood to carry 70 times more than if the oxygen were simply dissolved. (
  • Many worms have haemoglobin, but others and also most molluscs have different and more primitive oxygen-carrying pigments, which have not survived into higher forms of evolution. (
  • Haemoglobin not only distributes oxygen as it is required by the tissues but is also an important store of the gas. (
  • Healthy humans have about 15 g of haemoglobin per litre of blood, and this can bind with 200 ml of oxygen per litre. (
  • In a typical total blood volume of 5 litres, even though more than half is in the veins, we thus have about 0.75 litre of oxygen combined with haemoglobin in the blood, and we have about the same amount as gas in the lungs. (
  • If we were to breathe pure oxygen in a chamber at a pressure of three atmospheres, all the oxygen we need could be carried in solution and we would not need haemoglobin. (
  • This treatment is used for some conditions when haemoglobin is seriously deficient, but there are significant hazards of breathing high-pressure oxygen. (
  • Each haemoglobin molecule can combine with four oxygen molecules, but with no more. (
  • If the alveolar oxygen pressure is increased, for example by breathing more deeply or by inhaling pure oxygen, the haemoglobin in the blood will not take up any additional oxygen (see figure). (
  • The combination of oxygen with haemoglobin is not related linearly to the oxygen pressure, and this is crucially important in its function. (
  • As oxygen pressure reduces below that required for full saturation, haemoglobin is relatively little desaturated until and unless the oxygen pressure reaches about the level which blood normally encounters in the oxygen-using tissues: it then parts with it readily. (
  • Thus the properties of haemoglobin defend the oxygen supply against interruptions of breathing or shortage of oxygen in the atmosphere, whilst promoting its off-loading around the body. (
  • Hemoglobin forms an unstable, reversible bond with oxygen. (
  • For example, hemoglobin S is found in sickle-cell disease, a severe type of anemia in which the red cells become sickle-shaped when oxygen is in short supply. (
  • Hemoglobin is the protein in red blood cells that transports oxygen around the body. (
  • Scientists at St. Jude Children's Research Hospital have shown how a protein responsible for adapting to low oxygen conditions (hypoxia), causes increased expression of fetal hemoglobin (HbF) in adults. (
  • Hemoglobin is like a protein sponge that soaks up oxygen and allows red blood cells to ferry it throughout the body. (
  • Hemoglobin helps carry oxygen throughout your body and carries carbon dioxide to your lungs. (
  • Newswise - Scientists have made a surprising discovery this week that the iron containing heme molecule, which is a key part of hemoglobin, does a whole lot more than just help deliver oxygen from lungs to the body's cells. (
  • The finite element method was used to simulate the oxygen tension within cancerous tissue using P50s corresponding to different hemoglobin-based oxygen carriers (HBOCs). (
  • If your hemoglobin level is too low, you may not be able to supply the cells in your body with the oxygen they need to survive. (
  • Hemoglobin serves to carry oxygen to the tissues, and also carries the pigment that causes the blood to appear red. (
  • Myoglobin serves the same purpose as hemoglobin but is particular to the muscles, and is differentiated by the amount of oxygen and carbon monoxide it delivers to the tissues (more, and less, respectively). (
  • Not only can hemoglobin and myoglobin damage the kidneys, but their presence in the blood indicates low oxygen-carrying capacity, which can result in liver damage, serious illness, and shock, all of which serve to further decrease the amount of oxygen available through the muscles and blood. (
  • Hemoglobin is the protein in red blood cells that carries oxygen from the lungs to the rest of the body. (
  • As a person's blood sugar gets higher, glucose attaches to hemoglobin (a substance inside red blood cells that carries oxygen to cells). (
  • A systematic review of observational studies suggested that normovolemic patients can tolerate hemoglobins of 5-6 g/dL without affecting oxygen delivery. (
  • Hemoglobin is the substance which is present inside the red blood cells and carries oxygen to the various cells. (
  • Hemoglobin is found in red blood cells and helps to carry oxygen throughout the body. (
  • And then asks: does the spike protein, due to its amyloidogenic peptides, trigger misfolding of the haemoglobin into amyloid fibrils causing subsequent blood clots and oxygen incapacity? (
  • Hemoglobin diffusion has since a long time been recognized as facilitating the rate of oxygen diffusion through a solution. (
  • We address in this paper the question on how hemoglobin diffusion in the red blood cells can help the oxygen capture at the cell level and hence to improve oxygen transport. (
  • The importance of hemoglobin is made clear by the fact that only 1% of the transported oxygen is dissolved in blood plasma, while the remaining 99% is transported by hemoglobin. (
  • Hemoglobin transports oxygen from the lung to the tissue and helps transport carbon dioxide from the tissues to the lungs. (
  • In the absence of bound oxygen, the hemoglobin molecule has a low oxygen affinity. (
  • Tetrameric hemoglobin (Hb), the oxygen transporter of all vertebrates , has been for decades the ideal system to test for the validity of the MWC theory. (
  • Standard Pulse-oximetry measurement of the oxygen saturation of hemoglobin does not provide accurate results in the presence of methemoglobinemia [Ralston et al. (
  • Sickle-cell disease (SCD) is a genetic condition in which the red blood cells contain haemoglobin S (HbS), an abnormal form of the oxygen-carrying protein. (
  • Carboxyhemoglobin is a substance made in your blood when hemoglobin, a part of red blood cells, binds with carbon monoxide instead of oxygen. (
  • The hemoglobin A1C test , also known as the HbA1c test, glycated hemoglobin test, or glycohemoglobin, is a blood test typically used to diagnose diabetes or evaluate diabetes treatment. (
  • Hemoglobin A1c, also called glycated hemoglobin, is a marker of long-term blood sugar levels. (
  • The test, also called glycated hemoglobin, measures levels of blood glucose (sugar) over a period of two to three months. (
  • of these, 16 providers were excluded from analysis because nine used a contracted commercial laboratory to perform their hemoglobin measurements, and seven used hematocrit rather than hemoglobin assessment. (
  • What is the difference between high hemoglobin and hematocrit? (
  • People with high hemoglobin often also have high hematocrit, meaning they have irregularly high red blood cell counts. (
  • Hemoglobin and Hematocrit. (
  • Hemoglobin and hematocrit are unrelated to exposure. (
  • A decrease in haptoglobin can support a diagnosis of hemolytic anemia when seen with an increased reticulocyte count, decreased erythrocyte count, decreased hemoglobin and hematocrit. (
  • Each haemoglobin molecule consists of four iron-containing parts ( haems ) and four protein chains ( globins ). (
  • Adult hemoglobin contains four protein subunits - two beta-globin and two alpha-globin. (
  • High hemoglobin count happens when you have unusually high levels of a blood protein called hemoglobin. (
  • High hemoglobin (Hgb) count occurs when your red blood cells have an unusually high amount of the blood protein hemoglobin. (
  • The molecular interaction between hemoglobin (HHb), the major human heme protein, and the acridine dyes acridine orange (AO) and 9-aminoacridine (9AA) was studied by various spectroscopic, calorimetric and molecular modeling techniques. (
  • The destruction of blood cells within the blood vessels frees hemoglobin into the blood plasma (the yellowish colored liquid matter of the blood), where it binds with haptoglobin, a blood plasma protein which functions for the purpose of binding with free hemoglobin in order to prevent loss of iron. (
  • The separation of the hemoglobin depends on the charge that the globin protein carries. (
  • Hemoglobin is a protein that is found in the red blood cells. (
  • When protein synthesis was blocked by incubation of reticulocytes with puromycin, the specific activity of the α-chains of hemoglobin Gun Hill continued to increase due to direct exchange of α-subunits between the free pool and preformed hemoglobin Gun Hill. (
  • Is the Spike Protein Causative in Haemoglobin Disorders and Clotting? (
  • Is the spike protein acting as a prion with regard to haemoglobin molecules? (
