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 (from Greek Î¼ÏÎºÎ·Ï (mykes, mukos) fungus and ÏÎ¿Î¾Î¹ÎºÏÎ½ (toxikon) poison) is a toxic secondary metabolite produced by organisms of the fungi kingdom, commonly known as molds. 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 the same mycotoxin may be produced by several species.flatoxins are a type of mycotoxin produced by Aspergillus species of fungi, such as A. flavus and A. parasiticus. The umbrella term aflatoxin refers to four different types of mycotoxins produced, which are B 1, B 2, G 1, and G 2.
