Translations:Lipide/2/en

In living organisms lipids are mainly used as structural components in cell membranes, as energy stores or as signaling molecules. Most biological lipids are amphiphilic, i.e. they have a lipophilic hydrocarbon residue and a hydophilic head group, which is why they form [[micelles] or membranes in polar solvents such as water. The term fats is often used as a synonym for lipids, but fats are only a subgroup of lipids (namely the group of triglycerides).
