What is Allysine?

Plain description, key identifiers and synonyms

L-allysine is an optically active form of allysine having L-configuration. It has a role as a mouse metabolite, a Saccharomyces cerevisiae metabolite and a human metabolite. It is an allysine, an aminoadipate semialdehyde and a non-proteinogenic L-alpha-amino acid. It is a tautomer of a L-allysine zwitterion.
