The objective of this meta-analysis was to evaluate the response of growing-finishing pigs to different dietary methionine sources and to determine the ideal methionine:lysine ratio for nursery to finishing pigs. Data were obtained from peer-reviewed journals. Information were extracted from the material and methods and results sections of pre-selected articles. Forty one articles were included in the first database. Graphical and correlation analyses, multivariate exploratory analysis of factors, variance-covariance analysis, and non-linear models were applied to estimate nutritional requirements. Eighty-three percent of the articles in the database were not used for the determination of the methionine:lysine ratio because the diets did not meet the pigs lysine requirements. Methionine sources were compared using 21 articles of the first database, and performance differences were not found (P,0.05) among pigs fed diets containing L-methionine, DL-methionine, or methionine hydroxy analog. The ...
Cherest, H.; Surdin-Kerjan, Y.; Antoniewski, J.; Robichon-Szulmajster, H., 1973: S-adenosyl methionine-mediated repression of methionine biosynthetic enzymes in Saccharomyces cerevisiae
Twenty-four high producing Holstein cows (14 primiparous and 10 multiparous) were fed concentrate mix containing heat-treated soybean meal without or with 15 g of added DL-methionine daily provided as 50 g of ruminally protected methionine product during wk 4 through 16 postpartum. The 15% crude protein mixed diets contained 30% (dry matter basis) corn silage, 15% alfalfa hay, and 55% concentrate mix. Covariant adjusted yields of milk (34.6 and 33.1 kg/d), 4% fat-corrected milk (28.4 and 27.6 kg/d), and solids-corrected milk (29.0 and 28.5 kg/d) were not increased by feeding supplemental methionine. Percentages of fat (2.81 and 2.92) and protein (2.88 and 2.92) were similar, whereas total solids (11.49 and 12.69) and solids-not-fat (8.68 and 8.77) were higher with supplemental methionine. Dry matter intakes (20.2 and 21.0 kg/d) were higher when cows were fed supplemental methionine. Ruminal pH, volatile fatty acids, and ammonia as well as blood serum urea and glucose were generally unaffected by
Cysteine and methionine are sulfur-containing amino acids. Cysteine is synthesized from serine through different pathways in different organism groups. In bacteria and plants, cysteine is converted from serine (via acetylserine) by transfer of hydrogen sulfide [MD:M00021]. In animals, methionine-derived homocysteine is used as sulfur source and its condensation product with serine (cystathionine) is converted to cysteine [MD:M00338]. Cysteine is metabolized to pyruvate in multiple routes. Methionine is an essential amino acid, which animals cannot synthesize. In bacteria and plants, methionine is synthesized from aspartate [MD:M00017]. S-Adenosylmethionine (SAM), synthesized from methionine and ATP, is a methyl group donor in many important transfer reactions including DNA methylation for regulation of gene expression. SAM may also be used to regenerate methionine in the methionine salvage pathway [MD:M00034 ...

ERASMUS, L.J; BESTER, Z and COERTZE, R.J. Milk composition as technique to evaluate the relative bioavailability of a liquid rumen protected methionine source. S. Afr. j. anim. sci. [online]. 2013, vol.43, suppl.1, pp.86-92. ISSN 2221-4062.. Rumen protected amino acids (RPAA) are increasingly being used in dairy cattle diet formulation to obtain the required concentrations of lysine and methionine in metabolisable protein for optimal milk and milk protein production. The objective of this study was to evaluate the relative bioavailability of a liquid rumen protected lysine prototype using the milk composition technique. Forty mid-lactation Holstein cows were used in a complete randomised block design experiment and allocated to one of four experimental treatments. The treatments were: (1) Methionine deficient (Met-) diet, (2) Met- diet supplemented with Smartamine M (SMM), (3) Met- diet supplemented with liquid rumen protected prototype (LRPMet) and (4) Met- diet supplemented with DL Met ...
Objective: To test the hypothesis that an acute increase in plasma homocysteine produced by methionine is associated with an acute increase in pulse wave velocity.. Design: A double blind, cross over, placebo controlled design was used and pulse wave velocity, plasma homocysteine, total cholesterol: high density lipoprotein ratio, plasma triglyceride, oxidised low density lipoprotein cholesterol concentrations, apolipoproteins A1 and B, and C reactive protein were measured between 12.5 and 20 hours after methionine loading or placebo.. Results: Between 12.5 and 20 hours after exposure to a methionine loading test, arterial pulse wave velocity showed no significant difference compared with placebo. At 12 hours after exposure to the methionine loading test, in the presence of a controlled diet, triglyceride concentration significantly increased by 32.6% (p,0.02), cholesterol: high density lipoprotein ratio increased significantly by 22.5% (p,0.05) compared with placebo. Simultaneously, systolic ...

Oxidative stress and the formation of amyloid plaques containing amyloid-β (Aβ) peptides are two key hallmarks of Alzheimers disease. A proportion of methionine (Met) at position 35 within Aβ is oxidized to methionine sulphoxide (Met(OX)) within the Alzheimers plaques. These oxidative processes may be the key to understanding the early stages of Alzheimers disease. In vitro oxidation of Aβ, by the physiological oxidant H2O2, was monitored using (1)H NMR and mass spectrometry. Here we investigate the effect of Aβ methionine oxidation on fiber formation kinetics and morphology using the amyloid specific fluorescence dye Thioflavin T (ThT) and Transmission Electron Microscopy (TEM). Methionine oxidation reduces the total amount of fibers generated for both dominant forms of Aβ, however there are marked differences in the effect of Met(OX) between Aβ(1-40) and Aβ(1-42). Surprisingly the presence of Met(OX) reduces lag-times for Aβ(1-40) fiber formation but extends lag-times for ...

https://www.fightaging.org/archives/2014/05/a-report-from-the-first-international-mini-symposium-on-methionine-restriction-and-lifespan.php Methionine is an essential amino acid. Our metabolism cannot produce it, but is nonetheless an important raw material for the manufacture of proteins, and thus must be obtained in the diet. If you dont obtain enough of it, you die. Fortunately just about any sensible diet, and even most deficient diets, contain far more than you actually need to get by. Very few foodstuffs are lacking in methionine.. If you are the sort who likes undertaking strict and novel diets for the inherent challenge involved, rather than the outcome, then you should give up whatever you are doing right now and give a low methionine diet a try. You will be faced with challenging research to identify appropriate levels of methionine for a human low methionine diet, poor and contradictory nutritional data on the methionine content of various foodstuffs, and a comprehensive avoidance ...
And in reality, that makes perfect sense. Our hair has very little to do with improving the quality of our health, and thats why it is sacrificed by the body to protect more critical functions.. To really nourish and sustain healthy hair growth a diet which contains high levels of the fol-lowing active ingredients are important.. A side effect of these simple diet choices is the possibility of better health!. Sulphurated amino acids. Two of the sulphurated amino acids for new hair growth are L-methionine and L-cysteine. These are the basic building blocks of hair, they are essential for the formation of keratin and promote hair growth.. Your body can and does produce some cysteine on its own from another amino acid - methionine, which is also a sulfur-containing amino acid.

The metabolism of the polyamines spermidine and spermine is known to be enhanced in rapidly proliferating cells. Methionine is a precursor of the aminopropyl moieties of these amines. Therefore, it was of interest to study the effects of a methionine supplemented diet on polyamine metabolism and preneoplastic changes occurring in the intestinal tract of rats treated with the chemical carcinogen azoxymethane (AOM). Adult Wistar rats received 15 mg AOM/kg body wt (i.p.) once each week for 2 weeks. Thereafter, the rats were randomly divided into two groups and received controlled isoenergetic diets containing the same amount of folate, choline and vitamin B12 during 12 weeks: one group was kept on a standard diet; the other was fed the same diet, except that 1% L-methionine was added at the expense of carbohydrates. After 12 weeks, the administration of the methionine-supplemented diet stimulated the turnover rate of ileal epithelial cells, indicating enhanced crypt cell proliferation. Furthermore, ...
Of the 20 canonical amino acids, 18 are composed of carbon, hydrogen, nitrogen, and oxygen only. The remaining 2, methionine and cysteine, also contain 1 atom of sulfur. Because sulfur is not as electronegative as oxygen, the sulfur-containing amino acids play a key role in protein structure and synthesis.2 Methionine and cysteine also play important roles in cell metabolism. For instance, methionine serves as a substrate for S-adenosylmethionine, which is vital for methylation of nucleic acids, proteins, lipids, etc. In proteins, cysteine easily forms double bonds with other cysteine residues, thus determining tertiary structure and binding sites. Moreover, cysteine is substrate for glutathione, an important intracellular antioxidant, and H2S, a gas that can induce endothelial-dependent relaxation.3 Cysteine is considered a nonessential amino acid because it is synthesized from the essential amino acid methionine. However, because homocysteine lies in the pathway between methionine and ...
An early weaning is stressful and results in a gut barrier dysfunction and impaired innate immune responses in piglets mucous layer. The interruption of these physiological and immune functions aggravates the appearance of injuries and increases the oxidative stress resulting in diarrhea.. DL-Met and HMTBA, both available in the market as a source of methionine, are obtained through different processes of chemical synthesis resulting in a 50:50 mixture of L and D isomers. Recently, CJ has developed the technology to obtain a source of methionine through fermentation, thus achieving to launch in the market a product which is entirely made of L-Met isomer and 100% bio-available to animals.. Recent studies have demonstrated that there are functional requirements of Methionine (Met) in the GIT, particularly important in young animals. D-Met is not a Methionine source biologically active neither for animal cells nor for those of the gut, since it must be mainly converted to L-Met in the liver. ...
[11C]methionine (MET) has been used to monitor amino acid metabolism in tumors, the pancreas, liver, and myocardium. The aim of the present study was to standardize [11C]MET positron emission tomography (PET) by optimizing the timing of initiation of the scan and applying correction to the plasma concentrations of neutral amino acids (NAAs), where necessary. Sequential whole-body MET PET/computed tomography (CT) was performed in 11 normal adults after they had fasted for at least 4 h. After whole-body CT for attenuation correction and intravenous bolus injection of MET, the subjects were scanned from the parietal to the groin. The scanning was repeated six to seven times. Decay of radioactivity during the PET scan was corrected to the time of initiation of the first scan. The standardized uptake values (SUVs) were evaluated in various organs by setting regions of interest on the tomographic images. Plasma concentrations of NAAs were examined in relation to the SUV values. The SUVs in the pancreas

The amino acid methionine can enhance the survival capacity of embryos, when added to the cows diet during the prepartum and postpartum periods.
The accessibility of methionines in RNAase A to reaction with OBQ has been studied at highly acidic pH. The differences between the rate constants of reactions of the methionine and methionines of RNAase A with OBQ is a reflection on the limited accessibility of methionines in the protein conformation. Nevertheless, at sufficiently high OBQ concentration, all the four methionines of the enzyme can be modified. At lower concentration of OBQ, a derivative may be prepared in which a specific methionine is modified. The introduced chromophore ionizes at around pH 3 in this derivative. The derivative has partial activity towards RNA which is enhanced on addition of S-protein. ...

Methionine is an essential amino acid-one of the building blocks of proteins and peptides that your body cannot manufacture from other chemicals. The body uses methionine to manufacture creatine and uses the sulfur in methionine for normal metabolism and growth. One preliminary study suggests that methionine can prevent bacteria from sticking to urinary tract cells, 1 which may make it useful for preventing bladder infections. ( Cranberry juice is thought to help reduce the incidence of bladder infections in a similar fashion.)

Is there a soy barrier in aquafeeds? Reduced performance in high-soy feeds has been blamed on antinutrients, low methionine content and palatability issues.
One of the essential requirements of a good doggie food is that its first 5 key ingredients should be proteins, with an animal protein receiving primacy over plant-based proteins. It is true that certain plants also contain proteinaceous substances. However, when compared to animal proteins, it lacks certain amino acids that the dogs body cannot produce. For instance, the amino acids methionine, isoleucine, tryptophan, and lycine are found in very scarce amounts in certain plants whereas the same amino acids are quite abundant in animal proteins.. But what are amino acids anyway? This is the smallest unit that makes up a protein. It is similar to glucose, fructose, and lactose from carbohydrates and fatty acids from fat. When food is digested it is essentially broken down into its component molecules. The smallest possible molecule that can ever come from a protein is an amino acid.. Food is composed of proteins, fats, and carbohydrates which are then broken down into their smallest components. ...

Cholines function is similar to a vitamin. It is synthesized by the action of vitamin B12 and folic acid with amino acids methionine and glycine. However there is disagreement as to whether the amount would be adequate if there were none in the diet for a long period. If future researchers find a dietary need for it, it will be reclassified as a vitamin.. Choline functions with inositol as a basic constituent of a fatty substance called lecithin. It is water soluble and considered one of the B - complex vitamins and a lipotropic (fat emulsifier). It is present in the body of all living cells and widely distributed in animal and plant tissues.. Choline is used to make up acetylcholine, an important nerve transmitter which helps balance nervous activity. Acetylcholine plays an important part in memory and some studies have shown an increase in memory, intelligence and often helps those with premature senility when large amounts of choline and vitamin B5 are supplemented.. ...
... is the combined product of L-Methionine and D-Methionine. This is considered an essential amino acid and is necessary in the synthesis of S-Adenosylmethionine. It can be found in large amounts in fish, beans, eggs, Brazil nuts, lentils, garlic, yogurt, onions, various meats and other plants and seeds.Once consumed, the body combines DL-Methionine with ATP (Adenosine Triphosphate) where they goes on to produce SAMe. This is a requirement of at least 40 different biochemical reactions that are necessary towards sustaining life, and it is also indirectly present in a lot more.The reason that the body needs Methionine is that it helps produce Cysteine and Taurine. The body also uses these sulfur compounds to help develop the hair, nails, and skin. Sulfur also aids the kidneys in getting rid of metallic toxins present in there.Methionine is what is known as a lipotropic, which means that it helps the liver in rapidly processing fats. Chemicals also a part of the lipotropic group are Inositol,

How Specific Nutrients Fight Lead Poisoning. Vitamin C, Thiamine, taurine (a vitamin B6 / cysteine derivative), folate, vitamin B12, garlic and the amino acids methionine and glycine may offer significant advantages to lead exposed individuals with few risks. Calcium, iron, zinc, and selenium along with vitamins B6, D and E offer large advantages along with significant offsetting risks at high doses. Good intakes of phosphorus, magnesium, copper and glutamic acid (glutamate) offer possible smaller advantages with little risk. Curcumin, Pectin and cysteine offer possible significant advantages but their impacts are difficult to gauge. Melatonin may also have significant impacts but is only available from food in trace quantities. It must be emphasized that a combination of these nutrients is needed to offset leads diverse impacts, though if one were to nominate a single nutrient it would probably be vitamin C since, in spite of some inconsistent results, it has strong, widespread impacts ...

The pathway for the degradation of glyphosate (N-phosphonomethylglycine) by Pseudomonas sp. PG2982 has been determined using metabolic radiolabeling experiments. Radiorespirometry experiments utilizing 3-(14)C glyphosate revealed that approximately 50-59% of the C3 carbon was oxidized to CO(,2). Fractionation of stationary phase cells labeled with 3-(14)C glyphosate revealed that from 45-47% of the assimilated C3 carbon is distributed to proteins and that the amino acids methionine and serine are highly labeled. The nucleic acid bases adenine and guanine received 90% of the C3 label that was incorporated into nucleic acids, and the only pyrimidine base labeled was thymine. These results indicated that C3 of glyphosate was at some point metabolized to a C1 compound whose ultimate fate could be both oxidation to CO(,2) and distribution to amino acids and nucleic acid bases that receive a C1 group from the C1-donating coenzyme tetrahydrofolate. Pulse labeling of PG2982 cells with 3-(14)C glyphosate
In this diagram (active pathways shown by green arrows), methionine comes in at the lower left. As shown by the first star-pointed yellow arrow, the presence of methionine literally turns on the activity of the enzyme (called MAT) which turns methionine into SAMe (a necessary activation step, either to use the methionine as an important methylator or to get rid of it). SAMe is a very reactive (and therefore, potentially toxic) compound, and the liver gets rid of it by harmlessly giving the methyl group to a molecule of glycine (a step called transmethylation, performed by the enzyme GNMT).. That takes care of the "meth" part of methionine, so now the liver has to deal with the "thionine" part, by a process called transulfuration. When methionine gives up its methyl group, it becomes the amino acid homocysteine (Hcy; see lower right of figure). Hcy can be remethylated to methionine, but that process is turned off when methionine (and therefore, SAMe) is abundant (see black dashed arrow from right ...

Dear Sir, For a good moulting the factors good nutrition and a good physical health are of vital importance. First of all the birds should be healthy especially be free of parasites. When they are physically healthy after a good examination by a specialised veterinarian, it is absolutely unnecessary to give any kind of medication. For nutrition the amino acids methionine and cysteine are important as these are the building blocks of feathers as well as enough energy (carbohydrates or fat) because moulting needs a lot of energy. Also a good liver protection like sedochol could be of help. Also be aware that your birds are spared from too much work. Birds that have to breed a lot or even still train (tosses) are during moulting much more susceptible to various diseases. During moulting a bird should be able to use his energy for the new feathers, especially when the bird has done a lot of racing during the season. The moulting season is typically a period that serious illnesses can cause a lot ...
