a non-essential amino acid that is involved in the metabolic control of cell functions in nerve and brain tissue. it is biosynthesized from aspartic acid and ammonia by asparagine synthetase. (from concise encyclopedia biochemistry and molecular biology, 3rd ed) One of the nonessential amino acids. Dietary supplement, nutrient. Widely distributed in the plant kingdom. Isol. from asparagus, beetroot, peas, beans, etc. Asparagine (abbreviated as Asn or N; Asx or B represent either asparagine or aspartic acid) is one of the 20 most common natural amino acids on Earth. It has carboxamide as the side-chain's functional group. It is not an essential amino acid. Its codons are AAU and AAC. (Wikipedia)
