fattyacyl
Fattyacyl, typically written fatty acyl, refers to an acyl group derived from a fatty acid. In biochemistry, an acyl group is the carbonyl-containing fragment R-CO– that remains when a fatty acid loses its hydroxyl group. Fatty acyl groups are the hydrophobic tails of lipids and other molecules, and they can be attached to glycerol backbones, sphingolipids, or proteins, contributing to membrane structure and signaling.
Chemical characteristics and naming: Fatty acyl chains vary in length and degree of unsaturation, commonly ranging
Biological roles and metabolism: In cells, fatty acyl groups are activated to fatty acyl-CoA thioesters by acyl-CoA
Protein lipidation and regulation: Fatty acyl groups participate in protein lipidation, notably S-acylation, where a palmitoyl
