Waxes; A second group of neutral lipids that are of very important in physiological roles
2. Waxes are minor components of biological systems,
3. They consist of a long-chain fatty acid linked through an ester oxygen to a long-chain alcohol.
4. They play many important biological functions like; Physical protection of mammalian ears, Waterproofing of feathers in shore birds, Prevention of water loss by leaves and Structural materials in beehives.
Section 3.2Primary Structure: Amino Acids Are Linked by Peptide Bonds to Form Polypeptide Chains. Proteins are linear polymers formed by linking the α-carboxyl group of one amino acid to the α-amino group of another amino acid with a peptide bond (also called an amide bond).
Nucleic acids are the biopolymers, or small biomolecules, essential to all known forms of life. The term nucleic acid is the overall name for DNA and RNA.
