Disulfide bonds

The video tutorial introduces disulfide bonds, also known as SS bonds or disulfide bridges, and their importance in protein structure. It begins by explaining cysteine, a non-essential amino acid that contains sulfur and a thiol group, which is crucial for forming disulfide bonds. These bonds are covalent and form between two cysteine molecules, contributing to the protein's tertiary structure. The tutorial highlights the strength and significance of disulfide bonds in stabilizing proteins.
