| carboxyl group | -COOH group. One of the oxygens is double-bonded to the carbon atom, making it a carbonyl group, and the other oxygen is single bonded to the carbon on one side, and single bonded to the hydrogen on the other. The remaining bond on the carbon atom is attached to the rest of the molecule. Organic molecules containing carboxyl groups are an important, major group of compounds studied in the field of organic chemistry. (09 Oct 1997) |
|---|---|
| carboxyl terminal | The end of a polypeptide chain with the unattached carboxyl group (a -COOH group). Each amino acid in the middle of the chain has an amino group (a -NH2 group) on one side (which is attached to the carboxyl group of the previous amino acid) and a carboxyl group on the other side (which is attached to the amino group of the next amino acid). The other end of the polypeptide chain is called the amino terminal. (09 Oct 1997) |
| carboxyl-terminal residue | This amino acid residue defines the carboxylterminus of the polypeptide, its the only residue with a free alpha-carboxyl group. (09 Oct 1997) |
| amalgam carrier | An instrument used to transport triturated amalgam to a cavity preparation and to deposit it therein. (05 Mar 2000) |
| galactose-diphosphoglycosyl carrier lipid synthetase | <enzyme> Catalyses synthesis of gcl-pp-gal from udp gal and p-gcl; also catalyses exchange between the uridylyl moiety of udpgal and ump Registry number: EC 2.4.1.- (26 Jun 1999) |
| manifesting carrier | An organism heterozygous for what is ordinarily a recessive condition which, as a result of special mechanisms (such as lyonization, allelic exclusion, or a deletion in the homologous chromosome), has phenotypic manifestations. Synonym: manifesting carrier. (05 Mar 2000) |
| genetic carrier | An unaffected heterozygote bearing a usually harmful recessive gene, a cancer that bears a dominant but latent age-dependent trait to have offspring with unbalanced karyotypes. (05 Mar 2000) |
| carrier | 1. <genetics, microbiology> An individual who does not display the symptoms of a disease, but harbors the pathogen which causes it, or has the gene (or genes) for it, and can transmit the disease to others either through interacting with other individuals, or by passing the disease-causing gene (or genes) to offspring. 2. <pharmacology> A substance which transports things, such as a carrier protein. (09 Oct 1997) |
| carrier cell | <cell biology> A cell that is capable of phagocytosis. The main mammalian phagocytes are neutrophils and macrophages. Origin: L. Phagedaena, Gr Phago, To eat. (18 Nov 1997) |
| carrier electrophoresis | Electrophoresis done on a carrier (such as paper, polyacrylamide gel, etc.). (05 Mar 2000) |
| carrier-free | A substance in which a radioactive or other tagged atom is found in every molecule; the highest possible specific activity. (05 Mar 2000) |
| carrier proteins | Transport proteins that carry specific substances in the blood or across cell membranes. (12 Dec 1998) |
| carrier screening | Indiscriminate examination of members of a population to detect heterozygotes for serious disorders and counsel about the risks of marriages with other carriers, and by antenatal diagnosis where a married couple are both carriers; often sacrifices precision to simplicity and is most effectively applied to populations known to be at high risk. (05 Mar 2000) |
| carrier state | A condition in which a human who is not himself sick harbors an infective organism which may cause disease in those to whom it is transmitted. (12 Dec 1998) |
| carrier strain | A bacterial strain that is contaminated with a bacteriophage of low infectivity. Synonym: pseudolysogenic strain. (05 Mar 2000) |
