And the definition: "An L-alpha-amino acid which is biosynthesised from 3-phosphoglycerate (i.e. serine,
glycine, cysteine and homocysteine). A closed class."
(aside: what is a closed class? I see this on a handful of CHEBI terms but don't know what it means)
I think it's good to have the nomenclature be consistent because it's easy to get confused about whether a term is intentionally chirality agnostic or implicitly chiral (e.g many people use the CHEBI ID for serine when they mean L-serine)
Perhaps the reason this wasn't done because of glycine (achiral):
But glycine's position is already awkward if you look two hops up to L-alpha-amino acid
This is implicitly L based on graph:
