Summary
| Description |
Caption:(a) The primary structure is the sequence of amino acids that make up the
polypeptide chain. (b) The secondary structure, which can take the form of an alpha-helix or a beta-pleated sheet,
is maintained by hydrogen bonds between amino acids in different regions of the original polypeptide strand. (c) The
tertiary structure occurs as a result of further folding and bonding of the secondary structure. (d) The quaternary
structure occurs as a result of interactions between two or more tertiary subunits. The example shown here is
hemoglobin, a protein in red blood cells which transports oxygen to body tissues. |
