| peroxy-Y-base | <chemical> Tricyclic imidazo derivative of guanine Chemical name: 1h-imidazo(1,2-a)purine-7-butanoic acid, 4,9-dihydro-beta-hydroperoxy-alpha-((methoxycarbonyl)amino)-4,6-dimethyl-9-oxo-, methyl ester (26 Jun 1999) |
|---|---|
| methamphetamine base | A form of methamphetamine that can be readily volatilised. (05 Mar 2000) |
| complementary base pairing | <molecular biology> The pairing of complementary nucleotide bases (adenine and thymine, guanine and cytosine) to each other via hydrogen bonds from opposite strands of a double stranded nucleic acid (such as DNA or RNA), thereby holding the double-stranded nucleic acid together. (09 Oct 1997) |
| complementary base pairs | <molecular biology> The crucial property of DNA is that the two strands are complementary: Guanine and cytosine are complementary and pair up through their hydrogen bonds, as are adenine and thymine that only form two hydrogen bonds. (adenine and uracil in RNA). (18 Nov 1997) |
| wobble base | The 3' codon base that is less strictly specified in the genetic code. See: wobble, wobble hypothesis. (05 Mar 2000) |
| cranial base | The sloping floor of the cranial cavity. It comprises both the external base of skull (external view) and the internal base of skull (internal view). See: internal base of skull. Synonym: basis cranii, cranial base. (05 Mar 2000) |
| cyanine green G base | <chemical> Pharmacological action: dye Synonym: d.c. Green no. 6, 1,4-di-4-toluidinoanthraquinone, solvent green 3 (26 Jun 1999) |
| pressor base | One of several products of intestinal putrefaction believed to cause functional hypertension when absorbed, any alkaline substance that raises blood pressure. Synonym: pressor amine, pressor substance. (05 Mar 2000) |
| Schiff base | The reaction of a primary amine with an aldehyde or ketone yields an imine sometimes called a Schiff base. When an arylamine is used the Schiff base may form an intermediate in a staining reaction, for example for polysaccharides. (18 Nov 1997) |
| purine base | A purine. (05 Mar 2000) |
| pyrimidine base | <biochemistry> A family of 6-membered heterocyclic compounds occurring in nature in a wide variety of forms. They are planar and aromatic in character and include several nucleic acid constituents (cytosine, thymine, and uracil) and form the basic structure of the barbiturates. It is the parent compound of the pyrimidine bases of nucleic acid. (21 Jun 2000) |
| shellac base | A resinous wafer adapted to maxillary or mandibular casts to form baseplates. (05 Mar 2000) |
| hydroxy-Y base | <chemical> Chemical name: 1h-imidazo(1,2-a)purine-7-butanoic acid, 4,9-dihydro-beta-hydroxy-alpha-((methoxycarbonyl)amino)-4,6-dimethyl-9-oxo-, methyl ester Synonym: alpha-(carboxyamino)-beta-hydroxy-4,9-dihydro-4,6- dimethyl-9-oxo-1h-imidazo(1,2-a)purine-7-butyric acid dimethyl ester (26 Jun 1999) |
| skull base | The internal and external base of the cranium: respectively the inner and outer surfaces of the inferior region of the skull. The internal base constitutes the floor of the cranial cavity. (12 Dec 1998) |
| skull base neoplasms | Neoplasms of the base of the skull specifically, differentiated from neoplasms of unspecified sites or bones of the skull (skull neoplasms). (12 Dec 1998) |
