Lipids
Definition
•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.
