The oxidation pathway starts with the removal of the amino group by a transaminase; the amino group is then fed into the urea cycle. The other product of transamidation is a keto acid that enters the citric acid cycle. [79] Glucogenic amino acids can also be converted into glucose, through gluconeogenesis. [80]
A common example of an indolamine is the tryptophan derivative serotonin, a neurotransmitter involved in mood and sleep. [1] Another example of an indolamine is melatonin. In biochemistry, indolamines are substituted indole compounds that contain an amino group. Examples of indolamines include the lysergamides.
Each protein has its own unique amino acid sequence that is specified by the nucleotide sequence of the gene encoding this protein. The genetic code is a set of three-nucleotide sets called codons and each three-nucleotide combination designates an amino acid, for example AUG (adenine–uracil–guanine) is the code for methionine.
Histidine (symbol His or H) [2] is an essential amino acid that is used in the biosynthesis of proteins.It contains an α-amino group (which is in the protonated –NH 3 + form under biological conditions), a carboxylic acid group (which is in the deprotonated –COO − form under biological conditions), and an imidazole side chain (which is partially protonated), classifying it as a ...
Simple hydrolysis will split the polypeptide chain, where the displaced amino group becomes the new N-terminus. This is seen in the maturation of glycosylasparaginase. A β-elimination reaction also splits the chain, but results in a pyruvoyl group at the new N-terminus.

Threonine (symbol Thr or T) [2] is an amino acid that is used in the biosynthesis of proteins.It contains an α-amino group (which is in the protonated −NH + 3 form when dissolved in water), a carboxyl group (which is in the deprotonated −COO − form when dissolved in water), and a side chain containing a hydroxyl group, making it a polar, uncharged amino acid.
Leucine An α-amino acid that contains an α-amino group, an α-carboxylic acid group, and a side chain isobutyl group. Lysine An essential amino acid, which means that humans cannot synthesize it. Its codons are AAA and AAG. Alpha amino acids are also used in industry for the production of drugs, chiral catalysts, and biodegradable plastics. [AI]
