Vegetable oils and fish meat: lipid rich foods
What are lipids
Lipids, also called fats, are organic biomolecules composed mainly of hydrogen, oxygen, carbon molecules. Lipid composition also includes other elements, such as phosphorus.
Lipids have the characteristic of being insoluble in water. However, they are soluble in organic solvents (alcohol, ether, benzine, etc.).
Lipids have four basic functions in organisms:
- Power supply to the cells. However, they prefer to use the energy supplied by glycids first.
- Some types of lipids participate in the composition of cell membranes.
- In endodermic animals, act as thermal insulators.
- Facilitation of certain chemical reactions that occur in the body of living beings. This function has the following lipids: sex hormones, fat-soluble vitamins (vitamins A, K, D and E) and prostaglandins.
Main sources of lipids (food):
- Whole wheat
- Canola oil
