Entity of the month
The first amino acid ever isolated, L-asparagine (commonly known just as asparagine and abbreviated to L-Asn or N, CHEBI:17196) gets its name from the asparagus (Asparagus officinalis) juice from which it was first isolated over 200 years ago by the French chemists Louis Nicolas Vauquelin (1763–1829) and Pierre Jean Robiquet (1780–1840) . One of the 20 standard proteinogenic amino acids, it is synthesised in the body from oxaloacetic acid via L-aspartic acid. Since it does not have to be supplied in the diet, it is classed as a non-essential amino acid.
