Cell membranes · large biomolecule · many high energy bonds · nonpolar covalent bonds · includes waxes and steroids · consists mainly of carbon and hydrogen · more energy per gram than other biomolecules the biomolecule described is a a) carbohydrate. b) lipid. c) monosaccharide. d) protein.

The right answer is B) lipid

Name given to animal and vegetable fats, lipids or fats are molecules insoluble in water, but soluble in organic solvents. Living cells produce many of these compounds, most of which contain fatty acids or fatty acid derivatives.

Essential notions about their chemical structure

There are two families of lipids:

- Simple lipids composed only of carbon atoms, hydrogen and oxygen.

About 98% of edible lipids are triglycerides, products of the esterification of an alcohol, glycerol by fatty acids.

- Complex lipids:

Complex lipids are single lipids linked to sugar molecules, amino acids or radicals containing phosphorus or sulfur.

*Lipids also provide various other biological functions, including cell signaling (lipid signaling) and storage of metabolic energy by lipogenesis, energy released subsequently including β-oxidation.
