| aluminium |
aluminium (A light white metal, ductile and malleable, and a good conductor of electricity. It occurs widely in nature in clays and is the third most abundant element in the Earth's crust. It is extracted mainly from bauxite by electrolysis of a molten mixture of purified bauxite and cryolite. The metal and its alloys are used for aircraft, cooking utensils, electrical apparatus, and for many other purposes where its light weight is an advantage. Aluminium became implicated as an environmental health hazard in the 1980s on two counts. Biomedical scientists looking for possible causes of Alzheimer's disease, the premature senility indicated by loss of memory and confusion, found a circumstantial link with aluminium. The theory is a controversial one, Al) |

amine (One of a class of organic compounds which can be considered to be derived from ammonia by replacement of one or more hydrogens by organic radicals) |
|
| aminosyre |
amino acid (Organic compounds containing a carboxyl group (-COOH) and an amino group (-NH2). About 30 amino acids are known. They are fundamental constituents of living matter because protein molecules are made up of many amino acid molecules combined together. Amino acids are synthesized by green plants and some bacteria, but some (arginine, histidine, lysine. threonine, methionine, isoleucine, leucine, valine, phenylalanine, tryptophane) cannot be synthesized by animals and therefore are essential constituents of their diet. Proteins from specific plants may lack certain amino acids, so a vegetarian diet must include a wide range of plant products) |
