| adenine arabinoside | Misnomer for arabinosyladenine. (05 Mar 2000) |
| adenine deaminase | <enzyme> An enzyme that catalyses the hydrolysis of adenine to ammonia and hypoxanthine. A part of purine degradation. (05 Mar 2000) |
| adenine deoxyribonucleotide | Deoxyadenosine monophosphate, a hydrolysis product of DNA, differing from adenylic acid in containing deoxyribose in place of ribose. Synonym: adenine deoxyribonucleotide. (05 Mar 2000) |
| adenine nucleotide | A condensation product of adenosine and phosphoric acid; a nucleotide found among the hydrolysis products of all nucleic acids. 3'-Adenylic acid (adenosine 3'-monophosphate) and 5'-adenylic acid (adenosine 5'-monophosphate) differ in the place of attachment of the phosphoric acid to the d-ribose; deoxyadenylic acid differs in having H instead of OH at the 2' position of d-ribose. See: AMP. Synonym: adenine nucleotide. (05 Mar 2000) |

| adeno-associated virus | <virology> A genus of viruses in the family Parvoviridae which are all defective viruses (unable to replicate by themselves) and depend on the co-infection of their host cell by other, nondefective viruses to help them replicate. (09 Oct 1997) |
| adenoacanthoma | <tumour> A malignant neoplasm consisting chiefly of glandular epithelium (adenocarcinoma), usually well differentiated, with foci of metaplasia to squamous (or epidermoid) neoplastic cells. Synonym: adenoid squamous cell carcinoma. (05 Mar 2000) |
| adenoameloblastoma | A benign epithelial odontogenic tumour appearing radiographically as a well-circumscribed radiolucent-radiopaque lesion usually surrounding the crown of an impacted tooth in an adolescent or young adult; characterised histologically by columnar cells organised in a duct-like configuration interspersed with spindle-shaped cells and amyloid-like deposition that gradually undergoes dystrophic calcification. Synonym: adenoameloblastoma, ameloblastic adenomatoid tumour. (05 Mar 2000) |
| adenoblast | A proliferating embryonic cell with the potential to form glandular parenchyma. Origin: adeno-+ G. Blastos, germ (05 Mar 2000) |
