| iron-storage disease | The storage of excess iron in the parenchyma of many organs, as in idiopathic haemochromatosis or transfusion haemosiderosis. (05 Mar 2000) |
|---|---|
| iron-storage protein | <chemical> Soluble iron storage protein from e coli; different from ferritin and haemosiderin (05 Dec 1998) |
| iron succinyl milk protein complex | <chemical> Soluble iron complex with 5% iron content produced by reacting succinylated milk protein and ferric chloride Synonym: iron succinyl protein complex, itf 282, itf-282 (05 Dec 1998) |
| iron sulfate | A soluble iron salt frequently used as an iron supplement in tablets and liquid preparations. Synonym: ferrous sulfate. (05 Mar 2000) |
| iron-sulfur proteins | A group of proteins possessing only the iron-sulfur complex as the prosthetic group. These proteins participate in all major pathways of electron transport: photosynthesis, respiration, hydroxylation and bacterial hydrogen and nitrogen fixation. (12 Dec 1998) |
| total iron binding capacity | <biochemistry, haematology> A test that measures indirectly the transferrin level in the bloodstream. Transferrin is a protein that carries iron in the body. Normal values are 240 to 450 mcg/dl. This test is used to evaluate anaemia. Greater than normal total iron binding capacity can be seen in: iron deficiency anaemia, late pregnancy and polycythaemia vera. Lower than normal total iron binding capacity can be seen in cirrhosis, sickle cell anaemia, hypoproteinaemia, pernicious anaemia and haemolytic anaemia. The use of birth control pills can lead to increased total iron binding capacity measurements. Acronym: TIBC (12 Jan 1998) |
| ferric citrate iron reductase | <enzyme> Requires fmn, uses NADH; fre1 and fre2 provide membrane-associated ferric reductase activity for saccharomyces cerevisiae Registry number: EC 1.6.99.- Synonym: ferric iron reductase, iron reductase, ferric reductase, NADH-dependent, ferrireductase, iron (iii) reductase, ferric reductase, fre1 gene product, fre2 gene product, ferric-chelate reductase, NADH-dependent ferric-chelate reductase, NADH-dependent iron(iii)-chelate reductase, fecitr, NADH-fe(iii)-chelate reductase, nfr enzyme (26 Jun 1999) |
| Lillie's ferrous iron stain | <technique> A method using potassium ferrocyanide in acetic acid which demonstrates melanins as a deep green colour; lipofuscins and haem pigments are unreactive. (05 Mar 2000) |
| amino- | <prefix> Prefix denoting a compound containing the radical, -NH2. Origin: an(monia) + in(e) + -o- (05 Mar 2000) |
| amino acids | Organic compounds that generally contain an amino (-nh2) and a carboxyl (-cooh) group. Twenty alpha-amino acids are the subunits which are polymerised to form proteins. (12 Dec 1998) |
| amino acids, branched-chain | Amino acids which have a branched carbon chain. (12 Dec 1998) |
| amino acids, cyclic | A class of amino acids characterised by a closed ring structure. (12 Dec 1998) |
| amino acids, peptides, and proteins | Amino acids and chains of amino acids connected by peptide linkages. (12 Dec 1998) |
| amino acyl-tRNA ligases | <enzyme> Any of the group of ligases that catalyses the ATP-driven formation of a bond between an amino acid and a trna, activating the amino acids as a step in protein synthesis. Individual enzymes are highly specific for one amino acid and for any trna corresponding to that amino acid. Registry number: EC 6.1.1. (12 Dec 1998) |
| amino alcohols | Compounds possessing both a hydroxyl (-oh) and an amino group (-nh2). (12 Dec 1998) |
