Hormones, Vitamins and Enzymes role in health

Enzymes : Kirchoff first discovered enzyme in 1815. The term enzyme coined by Kuhne (1878). Enzyme may be defined as complex organic catalysts produced by the living cells for carrying out various reactions. Their action is highly specific i.e., a particular enzyme brings about a particular reaction only. Enzymes are proteins. Most active enzymes are associated with some non-protein component required for their activity. These are metal ions or smaller organic molecules called co-enzymes. The metal ions involved are Zn, Mg, Mn, Fe, Cu, K and Na.
