| Ames test (A bioassay developed by Bruce N. Ames in 1974, performed on bacteria to assess the capability of environmental chemicals to cause mutations) | 埃姆斯实验 | |
| 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) | 氨类 | |
| 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) | 氨基酸 | |
| ammonia (A colorless gaseous alkaline compound that is very soluble in water, has a characteristic pungent odour, is lighter than air, and is formed as a result of the decomposition of most nitrogenous organic material, NH3) | 氨 | |
| ammonification (Addition of ammonia or ammonia compounds, especially to the soil) | 氨化 | |
| ammonium (The radical NH4+, NH4) | 铵 | |
