Hspc hydrogenated soy phosphatidylcholine composition phosphatidylcholine mixture?

HSPC stands for hydrogenated soy phosphatidylcholine. It is not a single pure compound but a mixture of phosphatidylcholine (PC) species that have been hydrogenated to remove double bonds, giving predominantly saturated acyl chains.

Key points:
- The major component is typically a di-stearoyl PC species (DSPC, 18:0/18:0), but the exact mix also includes other di-saturated PC species derived from the soy lecithin and the hydrogenation process.
- The exact composition (percentages of DSPC, DPPC, and other saturated PC species) depends on the supplier and the specific product/batch. Some vendors label products as HSPC with approximate ranges, but those ranges are not universal.

What you can do for precise numbers:
- Look up the product datasheet or certificate of analysis (CoA) from the supplier for the exact composition of your lot.
- If you share the supplier name or product code, I can help summarize the reported composition or help interpret the CoA.
