Hspc hydrogenated soy phosphatidylcholine composition dspc?

Short answer:

- DSPC stands for 1,2-distearoyl-sn-glycero-3-phosphocholine. It is a single phosphatidylcholine species with two stearic acid (18:0) chains (18:0/18:0) at the sn-1 and sn-2 positions and a phosphocholine headgroup.

- HSPC stands for hydrogenated soy phosphatidylcholine. It is not a single molecule but a mixture of phosphatidylcholine species derived from soy PC that have been hydrogenated to saturate the fatty acyl chains. The composition is mainly saturated PC species (e.g., 18:0/18:0, 16:0/18:0, 16:0/16:0), with the exact distribution depending on the supplier and batch.

If you need exact percentages for a specific product, tell me the supplier and product name (for example, a lot from Lipoid or Avanti) and I can help interpret the specification.
