| amylo- | Starch, or polysaccharide nature or origin. Origin: G. Amylon, unmilled; starch, fr. A-+ myle, a mill (05 Mar 2000) |
| amylo-1,4:1,6-glucantransferase | 1,4-alpha-d-glucan branching enzyme |
| amylo-1,6-glucosidase | <enzyme> Catalyses endohydrolysis of 1,6-alpha-d-glucoside linkages at points of branching in chains of 1,4-linked alpha-d-glucose residues Registry number: EC 3.2.1.33 (26 Jun 1999) |
| amylobacter | <biology> A microorganism (Bacillus amylobacter) which develops in vegetable tissue during putrefaction. Origin: L. Amylum starch + NL. Bacterium. See Bacterium. Source: Websters Dictionary (01 Mar 1998) |
| amylocaine hydrochloride | 1-(Dimethylaminomethyl)-1-methylpropyl benzoate hydrochloride; benzoylethyldimethylaminopropanol hydrochloride;an early local anaesthetic once widely used but eventually abandoned because of side effects. (05 Mar 2000) |
| amyloclast | An obsolete term for amylase. Origin: amylo-+ G. Klastos, broken in pieces (05 Mar 2000) |
| amylodextrin | End product of hydrolysis of amylopectin by beta-amylase; further hydrolysis requires amylo-1,6-glucosidase, which attacks the branch points. Identified by its colour reaction with iodine (amylodextrin turns blue). Compare: achroodextrin, erythrodextrin. (05 Mar 2000) |
| amylogenesis | Biosynthesis of starch. Origin: amylo-+ G. Genesis, production (05 Mar 2000) |
| amylogenic | Relating to amylogenesis. (05 Mar 2000) |
| amylogenic body | A plant plastid involved in the synthesis and storage of starch. Found in many cell types, but particularly storage tissues. Characteristically has starch grains in the plastid stroma. (18 Nov 1997) |
| amyloglucosidase | A hydrolase removing terminal alpha-1,4-linked d-glucose residues from nonreducing ends of chains, with release of beta-d-glucose. Synonym: acid maltase, amyloglucosidase, gamma-amylase, glucoamylase. (05 Mar 2000) |
| amyloid | Glycoprotein deposited extracellularly in tissues in amyloidosis. The glycoprotein may either derive from light chain of immunoglobulin (AIO (amyloid of immune origin): 5-18 kD glycoprotein, product of a single clone of plasma cells, the N terminal part of lambda or kappa light chain) or, in what used to be referred to as AUO, amyloid of unknown origin, from serum amyloid A (SAA), one of the acute phase proteins that increases many fold in inflammation. The polypeptides are organised as a _ pleated sheet making the material rather inert and insoluble. Minor protein components are also found. Should be distinguished from _ amyloid deposited in the brain and that is derived from amyloid precursor protein (see amyloidogenic glycoprotein. (18 Nov 1997) |
| amyloid A-degrading serine protease | <enzyme> Reduced in amyloidosis associated with rheumatoid arthritis Registry number: EC 3.4.21.- Synonym: amyloid a-degrading activity, aad-protease (26 Jun 1999) |
| amyloid angiopathy | Deposition of acellular hyaline material in small arteries and arterioles of the leptomeninges and cerebral cortex in the elderly with resulting predilection for recurrent lobar intraparenchymal haematomas. (05 Mar 2000) |
