Sol. Zinc most likely functions as a Cofactor necessary for enzyme activity.
The carboxypeptidase is Synthesized in human body by the pancreas and secreted into the small intestine. Zinc is know to be cofactor for the enzyme of carboxypeptidase. The enzyme contains zinc(II) ions as a metal ion cofactor which is at the heart of the active site.

Electron configurations of transition metal ions Zinc is an essential mineral of great biological and health importance. In fact, it is the second most abundant transition metal after iron in our body. Most exists as Zn2+ ion in active site of enzymes, and they (more than 300) perform an array of functions. a. What is the electronic configuration of the Zn atom. b. Here comes the irritating part in chemistry. Although the 3d orbitals are placed higher in energy than...
