Avanti polar lipids hspc hydrogenated soy phosphatidylcholine composition?

Hydrogenated Soy Phosphatidylcholine (HSPC) from Avanti Polar Lipids is a hydrogenated form of soybean PC. It is a mixture of saturated phosphatidylcholine species, with the major components being saturated diacyl PCs. The exact composition is batch/lot dependent.

What you’ll typically see:
- Major PC species: DPPC (16:0/16:0) and DSPC (18:0/18:0) are the primary components.
- Other saturated PC species (e.g., 16:0/18:0) are usually present in smaller amounts.
- Very little (often trace) unsaturated PC species.

Important note:
- The precise percentages of each PC species are provided on Avanti’s Certificate of Analysis (CoA) for each lot. Composition can vary between lots.

How to get the exact composition for your lot:
- Go to the Avanti product page for Hydrogenated Soy Phosphatidylcholine (HSPC).
- Access the Certificate of Analysis (CoA) for your specific lot number; it lists the % by weight (or mol%) of the major PC species (e.g., DPPC, DSPC, etc.) and any remaining components.
- If you have a catalog or lot number, I can help you interpret the CoA once you share the details.

If you’re formulating liposomes and need a high Tm lipid, HSPC is a common choice because of its predominantly saturated PC content, but for exact composition and batch-to-batch consistency you’ll want the CoA for your specific lot.
