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]
Asparagine (symbol Asn or N [2]) is an α-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), an α-carboxylic acid group (which is in the deprotonated −COO − form under biological conditions), and a side chain carboxamide, classifying it as a polar (at physiological pH), aliphatic ...
For substances with an A- or α- prefix such as α-amylase, please see the parent page (in this case Amylase). A23187 (Calcimycin, Calcium Ionophore); Abamectine; Abietic acid

Amino acid biosynthesis is the set of biochemical processes (metabolic pathways) by which the amino acids are produced. The substrates for these processes are various compounds in the organism's diet or growth media. Not all organisms are able to synthesize all amino acids. For example, humans can synthesize 11 of the 20 standard amino acids.
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.
A branched-chain amino acid (BCAA) is an amino acid having an aliphatic side-chain with a branch (a central carbon atom bound to three or more carbon atoms). Among the proteinogenic amino acids, there are three BCAAs: leucine, isoleucine, and valine. [1] Non-proteinogenic BCAAs include 2-aminoisobutyric acid and alloisoleucine. Leucine ...
Dietary fibre from fruits, vegetables and grain foods. Insoluble dietary fibre is not absorbed in the human digestive tract but is important in maintaining the bulk of a bowel movement to avoid constipation. [5] Soluble fibre can be metabolized by bacteria residing in the large intestine.
