1stearoylsnglycero3phosphocholine

1-Stearoyl-sn-glycero-3-phosphocholine (L-ALPHA-LYSOPHOSPHATIDYLCHOLINE, STEAROY) is a chemical compound utilized in lipid metabolism studies.

SOPC is an asymmetrical phospholipid composed of a saturated fatty acid, stearic acid (18:0), at the sn-1 position and an unsaturated fatty acid, oleic acid (18:1), at the sn-2 position, SOPC is widely applied in membrane biology, liposome construction, and lipid–protein interaction research to model biological membranes, investigate bilayer dynamics, and support diverse biochemical, biophysical, and pharmaceutical formulation studies.

(Rac)-SOPC ((Rac)-PC(18:0/18:1)) ((Rac)-2-Oleoyl-1-stearoyl-sn-glycero-3-phosphocholine) is the racemic form of SOPC. SOPC is an asymmetrical phospholipid characterized by a saturated fatty acid (stearic acid/18:0) at the sn-1 position and an unsaturated fatty acid (oleic acid/18:1) at the sn-2 position. It is capable of stabilizing the outer segment membranes of frog rod cells.
