amino acid analysisAmino acids are organic compounds which are essential for all living organisms because they play a double role in cells, either connected to each other as building blocks of proteins or free as intermediates in metabolism. This article summarizes the relationship between the ...
The body does not synthesise a few amino acids. Hence, we need to include amino acid-rich food in our diet to get them. There is a wide range of foods rich in amino acids. For example, animal and plant-based protein sources have all the essential amino acids you need. Hence, a high...

The presence of D-amino acids was investigated in dairy products, in raw ham and in roasted coffee. The analysis was carried on by capillary gas chromatography, using a very stable tetraamidic selector derived from L-phenylalanine, which allowed the detection of D-alanine, D-aspartic acid, D...
Alkali hydrolysis was suitable for foods containing much amount of carbohydrate, and acid hydrolysis for that containing less amount of carbohydrate. In alkali hydrolyzate of foods, a tyrosine derivative was produced beside tyrosine. Although this derivative also gave red color with nitrosonaphthol, its...

Tryptophan was the limiting amino acid in the analyzed infant foods. A pap serving (250 ml) contributes significantly to fulfillment of the recommended dietary allowances of essential and semi-essential amino acids for infants (7–12 months old) and young children (1–3 years old).Lourdes...

Two of these, the toil of cysteine and the hydroxyl of tyrosine, are slightly ionized at PG 7 and can lose a proton much more readily than others in this class. The amides of asparagines and glutamine are readily hydrolyzed by acid or base to aspartic and glutamic acids, respectively. ...
Fig. 1. L-Amino Acid (Left) and D-Amino Acid (Right) They mainly exist in the form of D-type and L-type isomers in nature and have different physiological functions in organisms. D-amino acids and its derivatives accounted for under about 10% of the total have been found. D-amino ...
