Abstract
D-Serine has been isolated as the racemate from perchloric acid extracts of earthworms. It has been shown that the D-serine isolated is unlikely to have arisen as a result of racemization due to the isolation procedures or of any enzymic breakdown of lombricine or of D-serine ethanol-amine phosphodiester. D-Serine is presumed to be a part of the free amino acid pool in the earthworm. Experimental evidence has been adduced to show that, contrary to accepted beliefs, the optical homogeneity of serine is unaffected by exposure to alkaline solvents.Keywords
