Fatty acids and lipids
The term lipids encompasses all compounds which occur in the cell and which are poorly or not water-soluble. They are chemically very different, but all have predominantly non-polar molecules, although polar groups can also be included.
According to their chemical composition or their function, lipids can be divided into different groups. The most important are given here with examples:
- Hydrocarbons (squalene, carotenoids)
- Steroids (cholesterol, steroid hormones)
- Signal substances and hormones (prostaglandins, thromboxanes, leukotrienes)
- Vitamins (A, D, E or K) and cofactors (ubiquinone)
- Waxes (food additive E 903: carnauba wax)
- Neutral fats (mono-, di- and triacylglycerides)
- Phosphoglycerolipids (lecithin)
- Sphingolipids (cerebrosides, gangliosides, sphingomyelins, ceramides)
