What is the structure of and function of lipids?

• They have an amino acid and sequence that is programmed by a unit of inheritance known as a gene; thus, they can store and transmit hereditary information.

• They have many structures, resulting in a wide range of functions; thus they serve as structures for support, storage, transport, and cellular signaling; and defense against foreign substance.

• They are assembled from smaller molecules such as glycerol by dehydration reactions; thus, they cam store large amount of energy.
