Metals. Electropositive chemical elements characterized by ductility, malleability, luster, and conductance of heat and electricity. They can replace the hydrogen of an acid and form bases with hydroxyl radicals. (Grant & Hackh's Chemical Dictionary, 5th ed) . 0.73
Metals, Heavy. Heavy Metals . Metallic Pollutants . Toxic Metals . Metals with high specific gravity, typically larger than 5. They have complex spectra, form colored salts and double salts, have a low electrode potential, are mainly amphoteric, yield weak bases and weak acids, and are oxidizing or reducing agents (From Grant & Hackh's Chemical Dictionary, 5th ed) . 0.58
Trace Elements. Biometal . Biometals . Trace Element . Trace Mineral . Trace Minerals . Element, Trace . Elements, Trace . Mineral, Trace . Minerals, Trace . A group of chemical elements that are needed in minute quantities for the proper growth, development, and physiology of an organism. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed) . 0.54
RNA, Transfer, Met. tRNA(Met) . Met Transfer RNA . Methionine Specific tRNA . Methionine Specific tRNAm . RNA, Met Transfer . tRNA, Initiator . tRNA, Methionine-Specific . tRNAm, Methionine-Specific . Initiator tRNA . Methionine-Specific tRNA . Methionine-Specific tRNAm . RNA, Transfer, Initiator . tRNA(m)Met . tRNAMet . tRNA(f)Met . tRNA(i)Met . Transfer RNA, Met . A transfer RNA which is specific for carrying methionine to sites on the ribosomes. During initiation of protein synthesis, tRNA(f)Met in prokaryotic cells and tRNA(i)Met in eukaryotic cells binds to the start codon (CODON, INITIATOR). . 0.52
Metalloids. Intermediate Metals . Semi-Metals . Metals, Intermediate . Semi Metals . A class of nonmetals such as arsenic that have some of the chemical properties of a metal. . 0.49
