1. Tryptophan

   Tryptophan (symbol Trp or W) is an α-amino acid that is used in the biosynthesis of proteins. Tryptophan contains an α-amino group, an α-carboxylic acid group, and a side chain indole, making it a polar molecule with a non-polar aromatic beta carbon substituent. Tryptophan is also a precursor to the neurotransmitter serotonin, the hormone melatonin, and vitamin B3. It is encoded by the codon UGG. Like other amino acids, tryptophan is a zwitterion at physiological pH where the amino group is protonated (–NH+3; pKa = 9.39) and the carboxylic acid is deprotonated ( –COO−; pKa = 2.38).Humans and many animals cannot synthesize tryptophan: they need to obtain it through their diet, making it an essential amino acid.

1. tryptophan

   Tryptophan is an essential amino acid that is vital for the normal growth and development of the body, specifically in infants, and helps maintain nitrogen balance in adults. It aids in the creation of niacin, which is essential for the creation of serotonin, a neurotransmitter that helps regulate mood and sleep. Tryptophan is obtained through diet and is commonly found in foods like turkey, cheese, nuts, and fish.

1. Tryptophan

   Tryptophan is one of the 22 standard amino acids and an essential amino acid in the human diet. It is encoded in the standard genetic code as the codon UGG. Only the L-stereoisomer of tryptophan is used in structural or enzyme proteins, but the D-stereoisomer is occasionally found in naturally produced peptides. The distinguishing structural characteristic of tryptophan is that it contains an indole functional group. It is an essential amino acid, as demonstrated by its growth effects on rats.

1. Tryptophan

   An essential amino acid that is necessary for normal growth in infants and for NITROGEN balance in adults. It is a precursor of INDOLE ALKALOIDS in plants. It is a precursor of SEROTONIN (hence its use as an antidepressant and sleep aid). It can be a precursor to NIACIN, albeit inefficiently, in mammals.
