Proteins are synthesized by ribosomes translating mRNA into polypeptide chains, which may then undergo PTM to form the mature protein product. A covalent bond is a chemical bond that involves the sharing of electrons to form electron pairs between atoms.These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding. Hence, the electron pair is not equally shared in hybridized disulfide orbital and shifted to the more electronegative atom. Disulfide Bridges.
