| bromosuccinimide | <chemical> A brominating agent that replaces hydrogen atoms in benzylic or allylic positions. It is used in the oxidation of secondary alcohols to ketones and in controlled low-energy brominations. Chemical name: 2,5-Pyrrolidinedione, bromo- (12 Dec 1998) |

| bromosulfophthalein | A triphenylmethane derivative excreted by the liver, used in testing hepatic function, particularly of the reticuloendothelial cells. Synonym: bromosulfophthalein, bromsulfophthalein. (05 Mar 2000) |
| bromotrichloromethane | <chemical> A potent liver poison. In rats, bromotrichloromethane produces about three times the degree of liver microsomal lipid peroxidation as does carbon tetrachloride. Chemical name: Methane, bromotrichloro- (12 Dec 1998) |
| bromouracil | <chemical> 5-bromo-2,4(1h,3h)-pyrimidinedione. Brominated derivative of uracil that acts as an antimetabolite, substituting for thymine in DNA. It is used mainly as an experimental mutagen, but its deoxyriboside (bromodeoxyuridine) is used to treat neoplasms. Pharmacological action: antimetabolites, mutagens. Chemical name: 2,4(1H,3H)-Pyrimidinedione, 5-bromo- (12 Dec 1998) |
| bromoviridae | A family of RNA plant viruses with a wide host range in crops and horticultural species. All viruses are readily transmitted by mechanical means and some by insects and pollen. There are four genera: alfamovirus, bromovirus, cucumovirus, and ilarvirus. (12 Dec 1998) |
| bromovirus | A genus of tripartite plant viruses in the family bromoviridae. Transmission is by beetles. (12 Dec 1998) |
| Bromoviruses | <plant biology, virology> Plant viruses with a genome of three linear, positive sense ssRNA molecules. Named originally after brome grass. (13 Nov 1997) |
