INTRODUCTION

DL-Serine is a racemic mixture of both the D- and L-forms of the amino acid serine, which is a polar, nonessential amino acid. It  is an α-amino acid characterized by its hydroxyl-containing side chain, which enables it to take part in numerous biochemical reactions and synthetic processes. It functions as a pivotal intermediate in the biosynthesis of amino acids, including glycine and cysteine, underscoring its essential role in cellular metabolism. Moreover, it constitutes a critical pharmaceutical intermediate for the synthesis of a broad spectrum of therapeutic agents and drug candidates.

Manufacture

It is manufactured via microbial fermentation, typically using corn-derived glucose as the primary carbon source. During fermentation, selected microbial strains convert carbohydrates into L-Serine through enzymatic pathways followed by isolation, purification, and racemization steps to yield DL-Serine. This biotechnological route offers a sustainable and vegan-compatible alternative to traditional chemical synthesis.
