did you know that amino acids are the building blocks of proteins and the diversity in amino acid content and sequence is the source of the range in protein structures and functions?

There are 20 different, commonly found R groups in Amino acids. Cysteine makes disulfide bridges and are important in maintaining a 3-D shape of some protein molecules. Glycine is found in corners, while Proline is found in bends and loops of proteins. The basic structure of amino acids are A) Amino group B) Carboxyl Group C) Alpha carbon D) H E) R side chain

Monomers are formed with covalent bonding, one that requires energy, by condensation. This results in an H20 forming. Polymers are broken into monomers by hydrolysis, in which water is added to the system.

There are four major types of biological macromolecules - proteins, carbohydrates, lipids, and nucleic acids.

Peptide linkages are covalent bonds between two amino acids, formed by condensation (loss of H2O).

Amino Acids with electrically charged side chains:
