BACKGROUND: Evidence suggests a relation between plasma tryptophan concentrations and sleep and mental well-being. As no studies have been performed in pregnant women, we studied the relation of plasma tryptophan concentrations during pregnancy with sleep quality, and mood during and after pregnancy.METHODS: Pregnant women (n = 572) from the Growing Up in Singapore Towards healthy Outcomes study completed the Pittsburgh Sleep Quality Index (PSQI), the Edinburgh Postnatal Depression Scale (EPDS) and the State-Trait Anxiety Inventory (STAI) at 26-28 weeks gestation and three months post-delivery. Plasma tryptophan concentrations were measured at 26-28 weeks gestation. Poisson regressions estimated prevalence ratios (PR) for the association between tryptophan and poor sleep quality (PSQI global score , 5), probable antenatal depression (EPDS ≥ 15) and probable anxiety (STAI-state ≥ 41) were calculated adjusting for covariates.RESULTS: Mean plasma tryptophan concentrations was 48.0µmol/L (SD: ...
Groups of rats were deprived of food overnight and then given free access to diets designed to raise (carbohydrate) or lower (carbohydrate and large neutral amino acids) brain tryptophan concentrations. Similar diets were supplemented with 40% fat and fed to other groups. All animals were killed 2h after food presentation. Sera from animals fed carbohydrate plus fat contained 2.5 times as much free tryptophan concentrations did not differ. Similarly, sera from rats fed on carbohydrate, large neutral amino acids, and 40% fat contained 5 times as much free tryptophan as those from rats given this meal without fat, but brain tryptophan concentrations increased by only 26%. Correlations were made between brain tryptophan and (1) free serum tryptophan, (2) the ratio of free serum tryptophan to the sum of the other large neutral amino acids in serum that compete with it for uptake into the brain, (3) total serum tryptophan or (4) the ratio of total serum tryptophan to the sum of its circulating ...
© The Author 2016. Background: The effects of acute tryptophan depletion on human decision-making suggest that serotonin modulates the processing of rewards and punishments. However, few studies have assessed which of the many types of serotonin receptors are responsible. Methods: Using a within-subject, double-blind, sham-controlled design in 26 subjects, we examined whether individual differences in serotonin system gene transcription, measured in peripheral blood, predicted the effect of acute tryptophan depletion on decision-making. Participants performed a task in which they chose between successive pairs of fixed, lower-stakes (control) and variable, higher-stakes (experimental) gambles, each involving wins or losses. In 21 participants, mRNA from 9 serotonin system genes was measured in whole blood prior to acute tryptophan depletion: 5-HT1B, 5-HT1F, 5-HT2A, 5-HT2B, 5-HT3A, 5-HT3E, 5-HT7 (serotonin receptors), 5-HTT (the serotonin transporter), and tryptophan hydroxylase 1. Results: Acute
The purpose of this experiment was to study the effect of varying levels of tryptophan on the performance and carcass character of broiler. Trial 1: Ninety-six, five-week-old male Hubbard chickens, average weight 1.97 kg, were used in the trial. All birds were allocated into 3 treatments of 32 birds each. Each bird was kept in an individual cage. The trial period was 3 weeks. Treatment 1: Tryptophan content 0.198%. Treatment 2: Tryptophan content 0.228%. Treatment 3: Tryptophan content 0.258%. Trial 2: Ninety-six, three-week-old male Hubbard chickens, average weight 1.23 kg, were randomly distributed into the following two treatments. Each treatment had 48 birds. Treatment 1: Tryptophan content 0.167%. Treatment 2: Tryptophan content 0.198%. Trial 3: Ninety-six, two-week-old Hubbard chickens, average body weight 0.72 kg, were used in this experiment. There were three treatments as follows. Treatment 1. Tryptophan content 0.136%. Treatment 2. Tryptophan content 0.167%. Treatment 3. Tryptophan ...

AU - Akkerman, S.. AU - Steinbusch, H.P.. AU - Prickaerts, J.H.H.J.. PY - 2008/1/1. Y1 - 2008/1/1. N2 - The underlying mechanism of short-term memory improvement after inhibition of specific phosphodiesterases (PDEs) is still poorly understood. The present study aimed to reveal the ability of PDE5 and PDE2 inhibitors, that increase cyclic guanosine morrophosphate (cGMP) and both cyclic adenosine monophosphate (cAMP) and cGMP, respectively, to reverse an object recognition deficit induced by acute tryptophan depletion. Acute tryptophan depletion is a pharmacological challenge tool to lower central serotonin (5-hydroxytryptamine; 5-HT) levels by depleting the availability of its dietary precursor tryptophan. Short-term object memory was tested in male Wistar rats by exposing them to the object recognition ...

This report reviews the amino acid tryptophan which is an essential amino acid in the diet of Australian poultry. Reliable values of total and digestible tryptophan in feedstuffs are needed because tryptophan is often the third most limiting amino acid in poultry diets. Understanding the inclusion of tryptophan in poultry diets will also facilitate the strategic use of commercially available synthetic, feed-grade tryptophan in the Australian poultry industry.
TY - JOUR. T1 - Solvent-Slaved Dynamic Processes Observed by Tryptophan Phosphorescence of Human Serum Albumin. AU - Draganski, Andrew R.. AU - Friedman, Joel M.. AU - Ludescher, Richard D.. PY - 2017/3/14. Y1 - 2017/3/14. N2 - Despite extensive experimental and computational efforts to understand the nature of the hierarchy of protein fluctuations and the modulating role of the protein hydration shell, a detailed microscopic description of the dynamics of the protein-solvent system has yet to be achieved. By using single tryptophan protein phosphorescence, we follow site-specific internal protein dynamics over a broad temperature range and demonstrate three independent dynamic processes. Process I is seen at temperatures below the bulk solvent Tg, has low activation energy, and is likely due to fast vibrations that may be enabled by water mobility on the protein surface. Process II is observed above 170 K, with activation energy typical of β relaxations in a glass; it has the same temperature ...
Tryptophan is a very industrious amino acid. As an essential amino acid, tryptophan must be eaten in our diet. It does its job by assisting and boosting multiple systems in our body to also do theirs. Tryptophan is the nutritional social worker in our body who helps everyone else but risks getting worn out and depleted in the process.. Once we eat tryptophan in a protein-based food, it can be converted into serotonin during the day and melatonin at night. However, the main route for tryptophan is the production of vitamin B3. In fact, more than 90% of the tryptophan we eat becomes vitamin B3 when we are stressed and have not eaten enough of this important vitamin. If we consume enough vitamin B3, the route from tryptophan to vitamin B3 is interrupted and most of the tryptophan we consume becomes serotonin and melatonin. Therefore, vitamin B3 is known as a "stress" vitamin.. The interesting history of tryptophan and vitamin B3 goes back more than a century, when an illness youve probably never ...
Biosynthesis of the aromatic amino acids tryptophan, tyrosine, and phenylalanine proceeds via a common pathway to chorismate, at which point the pathway branches (CITS:[Jones][1943992]). One branch proceeds to tryptophan, and the other to tyrosine and phenylalanine (CITS:[Jones]). The series of reactions to chorismate, called the shikimate pathway, and the series of reactions from chorismate to tryptophan have been found to be common to all eukaryotes and prokaryotes studied thus far (as reported in (CITS:[1943992])). In contrast, there appears to be two separate routes from chorismate to tyrosine and phenylalanine, only one of which has been found in S. cerevisiae (CITS:[1943992]). Aromatic amino acid biosynthesis in S. cerevisiae is controlled by a combination of feedback inhibition, activation of enzyme activity, and regulation of enzyme synthesis (CITS:[Jones][1943992]). The first step in the tryptophan branch is feedback inhibited by tryptophan, and the first step in the ...
The native form of turkey liver fructose 1,6-bisphosphatase (FbPase) consists of four identical subunits, each of which contains one tryptophan residue. The fluorescence emission spectra of the tryptophan residues have been recorded as a function of changes in pH, substrate (fructose 1,6-bisphosphate) and inhibitor (adenosine-5 monophosphate) binding, and the addition of the metal cofactors Mg+2, Mn+2 and Co+2 . Changes in the fluorescence emission spectra of the tryptophan residues indicate that conformational changes in the enzyme occur under the above conditions.
Sodium Dodecyl Sulfate, or SDS, is an anionic detergent with widespread use in industrial and household cleaning products, scientific laboratories, and personal care products such as toothpaste and shampoo. The potential toxicity of SDS has been well-characterized in whole organism studies and its potential effects on the environment continue to be studied. Herein, we undertake a chemical-genetic screen to explore whether low concentrations of SDS have any discernible effects at the cellular level. Our screen of the homozygous diploid yeast deletion collection identified numerous gene deletions that confer sensitivity to SDS. Subsequent bioinformatic and biological analyses reveal that yeast unable to synthesize tryptophan are especially sensitive to the presence of SDS. Interestingly, even wild-type yeast with an intact tryptophan biosynthetic pathway exhibit growth defects in the presence of SDS on media lacking tryptophan. Altogether, we have shown that low levels of SDS, primarily through ...

Tryptophan fluorescence quenching is a type of fluorescence spectroscopy used for binding assays. The assay relies on the ability to quench the intrinsic fluorescence of tryptophan residues within a protein that results from changes in the local environment polarity experienced by the tryptophan(s) upon the addition of a binding partner or ligand. The quenching can arise from local changes near the interaction site or from binding-induced conformational changes. In cases where the titrant absorbs at or near the excitation or emission wavelengths of tryptophan, significant quenching can occur even without an interaction. This is known as the inner filter effect. This protocol describes how to use tryptophan fluorescence quenching to investigate the binding affinity of a protein for its partner/ligand and how to check and correct for the inner filter effect. As an example, we measured the binding affinity of the haem-binding protein, HusA, from Porphyromonas gingivalis for haem, and showed how we
The time-resolved fluorescence decay of single tryptophan (Trp) proteins is typically described using either a distribution of lifetimes or a sum of two or more exponential terms. A possible interpretation for this fluorescence decay heterogeneity is the existence of different isomeric conformations of Trp about its (chi) +1) and (chi) +2) dihedral angles. Are multiple Trp conformations compatible with the remainder of the protein in its crystallographic configuration or do they require repacking of neighbor side chains? It is conceivable that isomers of the neighbor side chains interconvert slowly on the fluorescence timescale and contribute additional lifetime components to the fluorescence intensity. We have explored this possibility by performing minimum perturbation mapping simulations of Trp 28 and Trp 31 in thioredoxin (TRX) using CHARMm 22. Mappings of Trp 29 and Trp 31 give the TRX Trp residue energy landscape as a function of (chi) +1) and (chi) +2) dihedral angles. Time-resolved ...
Objective- Apolipoprotein A-I (apoAI) acts as an ABCA1-dependent acceptor of cellular phospholipids and cholesterol during the biogenesis of HDL, but this activity is susceptible to oxidative inactivation by myeloperoxidase. We tried to determine which residues mediated this inactivation and create an oxidant-resistant apoAI variant.. Methods and Results- Mass spectrometry detected the presence of tryptophan, methionine, tyrosine, and lysine oxidation in apoAI recovered from human atheroma. We investigated the role of these residues in the myeloperoxidase-mediated loss of apoAI activity. Site-directed mutagenesis and chemical modification were used to create variants of apoAI which were tested for ABCA1-dependent cholesterol acceptor activity and oxidative inactivation. We previously reported that tyrosine modification is not required for myeloperoxidase-induced loss of apoAI function. Lysine methylation did not alter the sensitivity of apoAI to myeloperoxidase, whereas site-specific ...
How do people sustain resources for the benefit of individuals and communities and avoid the tragedy of the commons, in which shared resources become exhausted? In the present study, we examined the role of serotonin activity and social norms in the management of depletable resources. Healthy adults, alongside social partners, completed a multiplayer resource-dilemma game in which they repeatedly harvested from a partially replenishable monetary resource. Dietary tryptophan depletion, leading to reduced serotonin activity, was associated with aggressive harvesting strategies and disrupted use of the social norms given by distributions of other players harvests. Tryptophan-depleted participants more frequently exhausted the resource completely and also accumulated fewer rewards than participants who were not tryptophan depleted. Our findings show that rank-based social comparisons are crucial to the management of depletable resources, and that serotonin mediates responses to social norms.
Tryptophan amino acid is the essential amino acid. This means it must be provided through food to the body. It is one of the amino acids which in its molecule contains an indole ring. Tryptophan is glucogenic as well as ketogenic amino acid. It has codon UGG. It has two stereoisomers, namely L-tryptophan and D-tryptophan.. L-tryptophan can only be utilized in the structure or enzymes proteins while D - tryptophan is normally present in naturally occurring peptides. Tryptophan has aromatic side chain and is relatively polar. The N of the imidazole ring present in tryptophan gives polarity to this amino acid. It is genetically coded also.. ...

Studies performed during the past decade have shown that the rates at which certain neurons produce and release their neurotransmitters can be affected by precursor availability, and thus by the changes in plasma composition that occur after ingestion of the precursors in purified form or as constituents of foods. Thus, tryptophan administration or a plasma ratio of tryptophan to other large neutral amino acids, thereby raising brain tryptophan levels, increasing the substrate saturation of tryptophan hydroxylase, and accelerating the synthesis and release of serotonin. Tyrosine administration or a high-protein meal similarly elevates brain tyrosine and can accelerate catecholamine synthesis in the CNS and sympathoadrenal cells, while the consumption of lecithin or choline increases brain choline levels and neuronal acetylcholine synthesis. The physiologic and biochemical mechanisms that must exist in order for nutrient consumption to affect neurotransmitte synthesis have been characterized and ...

Tryptophan is essential for the biosynthesis of biogenic amines. The correct ingestion of this amino acid is vital in the newborn for correct growth. An ion-exchange HPLC method is described for the assay of tryptophan in breast milk. The protein was hydrolysed by barium hydroxide and then assayed by the indicated chromatographic technique, establishing the conditions for the analysis. The values obtained confirmed the utility of the method for determining the tryptophan content in breast milk. The concentration of tryptophan found in the study population in mothers who had been breast-feeding for three months was 10.02 mgl−1 g−1 of protein.
The fluorescence properties of tryptophan residues are sensitive to the microenvironment of fluorophores in proteins. Therefore, fluorescence characteristics are widely used to study structural transitions in proteins. However, the decoding of the structural information from spectroscopic data is challenging. Here we present a review of approaches developed for the decomposition of multi-component protein tryptophan fluorescence spectra and correlation of these spectral parameters with protein structural properties.

Biased processing of ED-relevant stimuli (eg Fairburn, Shafran, & Cooper, 1999) and 5-HT function (Kaye, Fudge, & Paulus, 2009) are implicated in vulnerability to and the maintenance of eating disorders (EDs), but it is not known if these findings are connected: Could manipulating 5-HT function affect the processing of ED-relevant stimuli? To address this question we assessed emotional processing in female dieters (T+n=12, T-n=14) following acute low dose tryptophan depletion. ATD increased interference in the masked condition of the emotional Stroop to all negative emotional stimuli, in the absence of any other differences in emotional processing. These results suggest that ATD affects the processing of some negative (including ED-relevant) stimuli, and that reduced 5-HT function may be involved in some aspects of psychological vulnerability to EDs.

The aim of the study was to influence the serotonin-melatonin-system and thus to investigate its effect to milk synthesis and ejection in dairy cows. Melatonin concentration of heifers but not of lactating cows could be influenced after elevating plasma tryptophan concentration by oral administration of rumen protected tryptophan. A variation of the daily photoperiod affected prolactin , but not oxytocin concentration. Via directed use of artificial sunlight during milking oxytocin, but not prolactin, could be influenced. Furthermore a circadian rhythm of melatonin in milk was shown. « ...
Tryptophan is an essential amino acid that must be obtained from the diet. The unusual indole side chain of tryptophan is also the nucleus of the important neurotransmitter serotonin, which is biosynthesized from tryptophan.

With an awareness of which foods contains tryptophan, one of the eight essential amino acids, you can have a significant impact on your mood, nervous system and sleep.. Tryptophan plays an important role in the production of serotonin (the "good mood hormone"), melatonin (a sleep facilitator) and vitamin B3 (niacin) which helps to combat tiredness, depression and indigestion.. Your tryptophan intake should be sufficient (500 to 2000 milligrams per day is required) if you regularly eat meat (such as turkey, chicken, salami or liver), fish, dairy products or eggs.. Vegetarians can get tryptophan from brown rice, bananas, pumpkin seeds, almonds, cashew nuts, peanuts, brewers yeast, parsley and soya.. However, if you try to boost your tryptophan levels by eating too much animal protein, it will be counter-productive as the tryptophan has to compete with the seven other amino acids to cross into the brain. Its assimilation will therefore be limited.. Conversely, eating carbohydrates along with ...

Decreases in enzyme activity often have little effect on the flux carried by the pathway. Similarly, up-modulation of single genes, and hence of the dependent enzyme concentrations, is frequently found to be ineffective in increasing the flux in the pathway in which the enzyme occurs. This insensitivity to enzyme variation is demonstrated experimentally for five separate enzymes in the tryptophan synthesis system of yeast, first by down-modulation of the gene dose and secondly by increasing the dose using multi-copy vectors. Such a lack of response is discussed in terms of the concepts of metabolic control analysis. When these five enzymes, however, were simultaneously increased by a multi-copy vector carrying all five genes, a substantial elevation of the flux to tryptophan was observed. These findings revealed a new phenomenon, namely the more than additive effects on the flux of simultaneous elevations of several enzyme activities. ...
Serotonin is one of the brains primary mood chemicals. It influences your sleep patterns, hunger, anxiety levels, and temperature regulation. When your brain lacks serotonin, you are likely to become more anxious and you may be unable to sleep. It also impacts your appetite.. Unfortunately, one of the simplest ways to keep serotonin levels high is to consume high-glycemic carbohydrates, which you may know are fatiguing and fattening. On top of this, once you eat high-glycemic carbs, it takes about 20 minutes for the brain to send the satiety signal (Im full). So you keep eating those empty-calorie foods that raise insulin levels and create even more cravings for sweet, refined foods.. Luckily there is a better way to naturally raise serotonin levels. The amino acid tryptophan is essential for the manufacture of serotonin. When you eat enough low-glycemic carbohydrates, a greater supply of tryptophan gets transported to the brain, where it generates serotonin. Foods naturally high in tryptophan ...
Accumulation of somatic mutations is critical for the transition of a normal cell to become cancerous. Mutations cause amino acid substitutions that change properties of proteins. However, it has not been studied as to what extent the composition and accordingly chemical properties of the cell proteome is altered as a result of the increased mutation load in cancer. Here, we analyzed data on amino acid substitutions caused by mutations in about 2000 protein coding genes from the Cancer Cell Line Encyclopedia that contains information on nucleotide and amino acid alterations in 782 cancer cell lines, and validated the analysis with information on amino acid substitutions for the same set of proteins in the Catalogue of Somatic Mutations in Cancer (COSMIC; v78) in circa 18,000 tumor samples. We found that nonsynonymous single nucleotide substitutions in the analyzed proteome subset ultimately result in a net gain of cysteine, histidine, and tryptophan at the expense of a net loss of arginine.
