Amino acid tryptophan

Little is known about the role of amino acids in cellular signaling pathways, especially as it pertains to pathways that regulate the rate of aging. However, it has been shown that methionine or tryptophan restriction extends lifespan in higher eukaryotes and increased proline or tryptophan levels increase longevity in C. elegans.

In the present paper, the fluorescence sensor based on Schiff base and boric acid was developed for easy and rapid detection of L-tryptophan in different samples such as milk and bovine serum albumin. The photoluminescence intensity was measured by using fluorescent measurements and the results indicated that the developed fluorescent sensor was exhibited selective, sensitive, reliable determination against L-tryptophan, and a series of various analytes such as cations, amino acids, and organic compounds were used to investigate the selectivity of the fluorescent chemosensor.

Free amino acids are found in spermatozoa and seminal plasma. Their qualitative and quantitative presence have been affected by many factors. Under in vitro storage conditions, their effects on spermatozoa in animal species and also human have been concerned over the last decades. In this study, the effects of tryptophan, phenylalanine and cysteine on DNA integrity, lipid peroxidation, viability and motility parameters in spermatozoa of the common carp (Cyprinuscarpio) were assessed during short-term storage.

French bean and Pea are an important vegetable crop consumed by human being as green pods and dry seeds due to its high nutritive value as the source of the amino acid, lysine and tryptophan as well as provides valuable dietary protein in the human diet. Considering its use as a vegetable which fits well indifferent cropping systems, there is need for improvement and development of cultivars to specific agro ecological conditions. The knowledge of genetic diversity is an important tool for any breeding programme aimed to exploit hybrid vigour.

High performance liquid chromatography was applied for the determination of tryptophan in food. The sample was hydrolyzed in a duration from 16 to 24 hour by protease enzyme at 50o C. The extract was separated on the C8 reversed phase column with mobile phase of NaH2PO4 50mM pH 2.3: Methanol (82:18; v/v). The linearity of the method was kept in the range of 0.5 - 50 mg/L. Limit of detection was found to be 4.6 mg/100g.

Maize (Zea mays L) is one of the most versatile emerging crop grown in diverse season and ecologies. Protein being the primary structural and functional component of every cell is one of the important ingredient that determines the quality of food throughout the world. The biological value of protein is increased in its new genotype–QPM by lowering zein content to 30% as a result the concentration of two essential amino acid lysine and tryptophan is increased.

Influence of varying Sulphur and zinc levels were studied on storage proteins and protein quality of Lentil (Lens culinaris). Application of 30 kg S/ha enhanced the soluble proteins, tryptophan, methionine, albumin and globulin. Similarly zinc application @ 30 kg/ha had positive impact on the soluble proteins (albumin and globulins) and amino acids (lysine and tryptophan).

Mushroom is a cash crop grown worldwide on small as well as commercial scale for domestic consumption and export. It is a rich source of proteins, minerals and vitamins with low calorie value with no cholesterol. It is well known alternate source of good quality protein which has higher concentration of amino acid viz., tryptophan and lysine in comparison to vegetable protein. The present investigation was carried out to know the nutritional and physiological along with growth and biomass of H. ulmarius.

Soybean (Glycine max) is a superior plant food known as miracle golden bean for its treasure trove of economical and preeminent protein than the high-priced meat protein. Soybean is not only known for its nutritional components but also provides significant health related benefits. This study was planned to analyze the effect of processing of soybean on its nutritional composition. Raw seeds with and without seed coats and germinated forms of three soybean varieties were analyzed for its nutritional and anti-nutritional components.

Maize is one of the most important grain crops in South Asia and is produced throughout the country under diverse environments. The grain of quality protein maize (QPM) varieties contain nearly twice as much lysine and tryptophan, amino acids that are essential for humans and monogastric animals. Evaluation of maize hybrids under different environments would be useful for identifying hybrids that combine stability with high yield potential for diverse environments.

The experiment was conducted to determine the effects of four amino acids (lysine, methionine, threonine and tryptophan) supplementation on growth performances and serum antibody titers to Gumboro disease (IBD, infectious bursal disease) in broiler chickens. Chicks were randomly assigned to 5 dietary groups (5 chicks/group as 12 replicates of 5 chicks) in a complete randomised experimental design. Group I served as control group, was fed a diet without any supplementation.

Maize, Zea mays L., is one of the important cereal crops with diverse uses as food, feed, fodder and industrial applications. As a food crop it is a primary source of nourishment to people in Africa, Latin America and South Asia. It is also the principal energy source used in poultry diets in most of the countries including India because of its high-energy value, palatability, presence of pigments and essential fatty acids.

Substituent constants and quantum chemical parameters were calculated from PM6, PM3, AM1, RM1 and MNDO. Hamiltonians were used to predict the corrosion inhibition potential of nine amino acids grouped under three skeletons. Skeleton I consisted of cysteine (CYS), serine (SER) and amino butyric acid (ABU). Those in skeleton II included threonine (THR), alanine (ALA) and valine (VAL) while those in skeleton III are aromatic amino acids, which included phenylalanine (PHE), tryptophan (TRP) and tyrosine (TYR).

Sample diets are shown in Tables 2 and 3 for the respective 5-8 and 17-19 wk periods for Treatments 1 through 4. The control diet (Treatment 1) includes animal protein because of its obvious economic advantage and widespread use. Valine content (as a percent of protein) is similar across ingredients; therefore diet protein in these sample diets was fixed by setting a valine specification. Supplemental lysine, methionine, and threonine were used so that all diets contained adequate amounts of these amino acids.
