Polyamine Compounds with many amino groups that are associated with nucleic acids. Related Terms: Nucleic acid A large molecule composed of nucleotide subunits.

[After the compounds are made]-often a dozen or so at a time-they then get sent to screening and they will be characterized for how tightly they bind. Oftentimes we're right that this one's the best one; this one's the worst one.

nucleosides - compound composed of a purine or pydimidine base linked to either a ribose or deoxyribose sugar. DNA and RNA are not polymers of nucleosides.

Vitamin An organic compound that is required in relatively small amounts for growth of an organism. Vitamins often function as coenzymes.

A class of natural and synthetic compounds that inhibit the growth of or kill other microorganisms. (See Antibiotic resistance, Bacteriocide, Bacteriostat.) Antibiotic resistance.

phosphorolysis Cleavage of a compound with phosphate as the attacking group: analogous to hydrolysis. phosphorylation Formation of a phosphate derivative of a biomolecule, most often by enzymatic transfer of a phosphate group from ATP.

This family is capable of oxidizing organic compounds including aromatic hydrocarbons to carbon dioxide with Fe(III) or other metals and metalloids including U(VI), Tc(VII), Co(III), Cr(IV), Au(III), Hg(II), ...
