Lipids Definition

Smith, Janice Gorzynski. General, Organic, & Biological Chemistry 2nd Ed. 3

•Lipids are biomolecules that are soluble in organic solvents and insoluble in water.

•They are not defined by a particular functional group, thus they have a variety of structures and functions.

•They contain many nonpolar C—C and C—H bonds and few polar bonds resulting in their water insolubility.

Lipids Waxes

Smith, Janice Gorzynski. General, Organic, & Biological Chemistry 2nd Ed. 9

Hydrolysis of a wax can occur with acids, bases, or enzyme catalyzed, reforming the fatty acid and alcohol.
