Describe the primary, secondary, tertiary, and quaternary structure of a protein
The primary structure of a protein is the amino acid sequence of the polypeptide. The secondary structure is determined by weak electrical forces between the amino acids, folding the peptide sequence into helixes and pleated sheets. The tertiary structure is the more complex three-dimensional shape based on the amino acid composition, positioning amino acids with hydrophobic amino acids on the inside and amino acids with hydrophilic side chains on the outside of the structure. Disulfide bonds between amino acids also contribute to the tertiary structure. Quaternary structure is determined by the association of individual polypeptides with each other, forming a larger complex of multiple polypeptide chains.
