Structure This is in reference to the fold like structure of a polypeptide chain that gives the protein a 3d like shape. There is 2 types of secondary structure which are: Alpha Helix This would resemble a coiled spring which is secured by hydrogen bonding in a polypeptide chain. Beta Pleated Sheet This would resemble folds/pleats that is held together again by a hydrogen bond between a polypeptide of the folded chain that lie next to each other. 3) Tertiary
