Hspc hydrogenated soy phosphatidylcholine mixture major components?

HSPC (hydrogenated soy phosphatidylcholine) is a mixture of saturated phosphatidylcholine species. The major components are:

- DPPC (1,2-dipalmitoyl-sn-glycero-3-phosphocholine; 16:0/16:0)
- DSPC (1,2-distearoyl-sn-glycero-3-phosphocholine; 18:0/18:0)

The exact ratio of DPPC to DSPC varies by supplier and batch (often roughly 1:1 to 1:2 in favor of DSPC), with other saturated PC species present in smaller amounts. If you need precise composition for a specific product, check the supplier’s specification sheet (e.g., Lipoid, Avanti) for the exact mol% of each PC species.
