This video tutorial reviews the four levels of protein structure: primary, secondary, tertiary, and quaternary. It explains how amino acid sequences form the primary structure, while secondary structures involve backbone interactions like beta-pleated sheets and alpha helices. Tertiary structure focuses on side chain interactions, including hydrophobic and hydrophilic effects, ionic bonds, and disulfide linkages. Finally, quaternary structure involves the assembly of multiple polypeptide chains, highlighting the complexity and functionality of proteins in biological processes.
