The scientific name for ceramides is N-acyl-sphingoid bases.
Ceramides are a significant group of sphingoid base derivatives. They are characterized by having a fatty acid linked to a sphingoid base through an amide bond. According to the provided reference, these fatty acids typically have chain lengths between 14 and 26 carbon atoms, and are mostly saturated or monounsaturated. It is also common for these fatty acids to have a hydroxyl group at the second carbon position.
Here's a breakdown of the components that define ceramides:
- Sphingoid Base: This is the core structure, a long-chain amino alcohol.
- Fatty Acid: Linked to the sphingoid base via an amide bond, usually having 14-26 carbon atoms.
- Amide Bond: The specific chemical bond that links the fatty acid to the sphingoid base.
Ceramides play a crucial role in various cellular processes, particularly in the formation and function of the skin barrier.
