Description
L-Serine Product Overview
L-Serine (C3H7NO3) is a white crystalline powder that dissolves well in water. It decomposes at about 228°C. The commercial grade is produced by fermentation or enzymatic processes.
Biotech and pharmaceutical companies use it in cell culture media and in amino acid infusion solutions. Cosmetic formulators add it to moisturizing products, because serine is one of the main components of the skin’s natural moisturizing factor. In chemistry, it is a chiral building block for pharmaceutical intermediates and peptides.
Food producers also use it in fortified foods where permitted. For other amino acids in our range, see Glycine, L-Threonine and L-Tyrosine.
