| Common Name | Pristanal |
|---|
| Description | Pristanal, also known as (2R)-pristanal or 2SPR-al, belongs to the class of organic compounds known as acyclic diterpenoids. These are diterpenoids (compounds made of four consecutive isoprene units) that do not contain a cycle. Thus, pristanal is considered to be an isoprenoid lipid molecule. Pristanal is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. |
