L-Serine | Premium Amino Acid for Pharma & Cosmetics | CAS 56-45-1
Overview
L-Serine is a vital, naturally occurring non-essential amino acid appearing as a white crystalline powder. Physiologically, it plays an indispensable role in cellular metabolism, functioning as a critical building block for proteins, purines, and pyrimidines. In the commercial sphere, L-Serine is highly prized as the primary component of the skin’s Natural Moisturizing Factor (NMF) and the essential precursor for advanced brain-health nutraceuticals like Phosphatidylserine (PS).
