General description
L-Homoserine is a variant of serine with an additional carbon on its side chain.
Application
L-Homoserine has been used as an internal standard for neurotransmitter analysis and amino acids quantification.
Biochem/physiol Actions
L-Homoserine is synthesized by deoxidation process, catalysed by homoserine dehydrogenase. This is one of the steps in the synthesis of L-threonine. The carbon flux in in bacteria such as E. coli is maintained by this reaction.
L-Homoserine is used in the biosynthesis of methionine, threonine and isoleucine.
