How are bonds formed and broken
WebDisulfide bonds are covalent interactions formed between the sulfur atoms of two cysteine residues. As structural bonds in proteins, disulfide bonds stabilize monomeric and multisubunit proteins [1] constituting the only natural covalent link between polypeptide strands. Furthermore, disulfide bonds are involved in enzyme catalysis [2], regulate … WebEsters are formed in condensation reactions and broken by hydrolysis. Fats and oils, important compounds in our diet, are naturally occurring esters and their structure explains their properties.
