L-Serine

Introduction

Product properties: L-Serine has little sweet taste, 228 °C decompounds, slightly soluble in water, does not dissolve in the ethyl

alcohol. It’s appearance is white-like crystalline powder.

Functions: Serine plays an important role in the catalytic function of many enzymes. It has been shown to occur in the active sites

of chymotrypsin, trypsin, and many other enzymes. The so-called nerve gases and many substances used in insecticides have

been shown to act by combining with a residue of serine in the active site of acetylcholine esterase, inhibiting the enzyme completely.

The enzyme acetylcholine esterase breaks down the neurotransmitter acetylcholine, which is released at nerve and muscle junctions

in order to allow the muscle or organ to relax. The result of acetylcholine inhibition is that acetylcholine builds up and continues to

act so that any nerve impulses are continually transmitted and muscle contractions do not stop. As a constituent (residue) of proteins,

its side chain can undergo O-linked glycosylation, which may be functionally related to diabetes. It is one of three amino acid residues

that are commonly phosphorylated by kinases during cell signaling in eukaryotes. Phosphorylated serine residues are often referred to

as phosphoserine. Serine proteases are a common type of protease.
