History and Uses: Although calcium is the fifth most abundant element in the earth's crust, it is never found free in nature since it easily forms compounds by reacting with oxygen and water.Metallic calcium was first isolated by Sir Humphry Davy in 1808 through the electrolysis of a mixture of lime (CaO) and mercuric oxide (HgO).ther common compounds of calcium include: calcium sulfate (CaSO 4), also known as gypsum, which is used to make dry wall and plaster of Paris, calcium nitrate (Ca(NO 3) 2), a naturally occurring fertilizer and calcium phosphate (Ca 3 (PO 4) 2), the main material found in bones and teeth.
incretin: A gastrointestinal hormone causing an increase in the amount of insulin released from the beta cells of the islets of Langerhans after eating, even before blood glucose levels become elevated.
A mycotoxin is a toxic secondary metabolite produced by organisms of the fungus kingdom and is capable of causing disease and death in both humans and other animals. The term 'mycotoxin' is usually reserved for the toxic chemical products produced by fungi that readily colonize crops. One mold species may produce many different mycotoxins, and several species may produce the same mycotoxin.
