Phospholipide in öl
WebPhospholipids are molecules that form the cell membrane. They consist of a polar phosphate head group and two nonpolar fatty acid tails joined by a glycerol backbone. The phosphate group can link with different molecules, such as serine or choline, to generate diverse kinds of phospholipids. The fatty acid tails can have cis or trans double ... WebNov 8, 2024 · The simplest of the charged lipids, fatty acids are a large group of amphipathic molecules consisting of short, medium or long-chain hydrocarbon “tails” (C4 to C36) and a polar carboxylic acid “head”. The aliphatic chains can be fully saturated or unsaturated to some extent, and provide the hydrophobic character of the fatty acid.
