Acyl chain

An acyl chain is a chain of carbon and hydrogen atoms that forms part of certain molecules called fatty acids and lipids. Think of it as a flexible, hydrocarbon "tail" attached to a larger molecule. These chains can vary in length and can be saturated (no double bonds) or unsaturated (with double bonds), influencing the molecule's properties like fluidity and function. Acyl chains are important in biological systems for constructing cell membranes, storing energy, and participating in signaling processes. They play a key role in maintaining the structure and function of fats and lipids in living organisms.
