The primary structure of a protein is determined by the sequence of amino acids. This sequence is crucial because it dictates:
- AThe solubility of the protein in water.
- BThe formation of disulfide bridges only.
- CThe higher-order structures (secondary, tertiary, quaternary) and ultimately the protein's function.
- DThe rate at which the protein is degraded in the cell.
