1️⃣ Product Description 🧬

🔹 Phosphatidylserine (PS) is a naturally occurring phospholipid composed of a glycerol backbone, two fatty acid chains, a phosphate group, and the amino acid serine as its polar head group.

🔹 PS is an important structural component of cell membranes, particularly abundant in neuronal membranes, and plays a key role in cell signaling, membrane fluidity, and apoptosis regulation.

🔹 It is widely used in biochemical, life science, and pharmaceutical R&D as a functional phospholipid material.
