Lipide/en

Lipid is a collective term for completely or at least largely water-insoluble (hydrophobic] natural substances which, on the other hand, due to their low polarity are very well suited for hydrophobic or lipophilic Dissolve solvents. Their insolubility in water stems above all from the long hydrocarbon residues which the vast majority of lipids possess.

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).
