WebBond cleavage. In chemistry, bond cleavage, or bond fission, is the splitting of chemical bonds. This can be generally referred to as dissociation when a molecule is cleaved into two or more fragments. [1] In general, there are two classifications for bond cleavage: homo lytic and hetero lytic, depending on the nature of the process. WebThe most frequently found metal-binding sites in proteins are for iron, copper, zinc, and calcium. All but Ca + belong to the first transition series, beginning with Sc (Z = 21) and including Ti, V, Cr, Mn, Fe, Co, Ni, Cu, and Zn (Z = 30). In addition to calcium, Mg 2+ (a group IIa element) is frequently found bound to proteins.
