General description

L-Homoserine is a variant of serine with an additional carbon on its side chain.[1]

Application

L-Homoserine has been used as an internal standard for neurotransmitter analysis[2] and amino acids quantification.[3]

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.[4]
L-Homoserine is used in the biosynthesis of methionine, threonine and isoleucine.

This method for estimating clinically important amino acids in serum or urine within 40 min involves o-phthalaldehyde/2-mercaptoethanol derivatization and reversed-phase "high-pressure" liquid chromatography. Homocysteic acid is an internal standard, and homoserine and norvaline are reference peaks. For all the amino
