| lactometer | Synonym: galactometer. Origin: Lacto-+ G. Metron, measure (05 Mar 2000) |
|---|---|
| lactonase | <enzyme> Aldonolactonase (formerly EC 3.1.1.18) was combined with this Registry number: EC 3.1.1.17 Synonym: aldonolactonase, gulonolactone hydrolase (26 Jun 1999) |
| lactone | <chemistry> One of a series of organic compounds, regarded as anhydrides of certain hydroxy acids. In general, they are colourless liquids, having a weak aromatic odour. They are so called because the typical lactone is derived from lactic acid. Source: Websters Dictionary (01 Mar 1998) |
| lactonic | <chemistry> Pertaining to, or designating, an acid obtained by the oxidation of milk sugar (lactose), or derived from, lactone. Origin: From Lactose. Source: Websters Dictionary (01 Mar 1998) |
| lactoperoxidase | <enzyme> Peroxidase enzyme from milk that finds an important use in generating active iodine as a nonpermeant radiolabel for membrane proteins. (18 Nov 1997) |
| lactoprotein | <physiology> A peculiar albuminous body considered a normal constituent of milk. Origin: L.lac, lactis,milk + E. Protein. Source: Websters Dictionary (01 Mar 1998) |
| lactorrhoea | Synonym: galactorrhoea. Origin: Lacto-+ G. Rhoia, a flow (05 Mar 2000) |
| lactory | Lactiferous. "Lactory or milky plants." Source: Websters Dictionary (01 Mar 1998) |
| lactoscope | <instrument> An instrument for estimating the amount of cream contained in milk by ascertaining its relative opacity. Origin: L. Lac, lactis + scope. Source: Websters Dictionary (01 Mar 1998) |
| lactose | The major sugar in human and bovine milk. Conversion of lactose to lactic acid by Lactobacilli etc. Is important in the production of yoghurt and cheese. (18 Nov 1997) |
| lactose carrier protein | <protein> The best known example is the product of the lacY gene, coded for in the lactose operon and responsible for the uptake of lactose by E. Coli. (18 Nov 1997) |
| lactose factors | Plasmids which determine the ability of a bacterium to ferment lactose. (12 Dec 1998) |
| lactose intolerance | A disorder characterised by abdominal cramps and diarrhoea after the consumption of food containing lactose (for example milk, ice cream), believed to occur due to a deficiency of intestinal lactase (enzyme that breaks down lactose), may appear first in young adults who have previously tolerated milk well as infants. (27 Sep 1997) |
| lactose operon | Group of adjacent and coordinately controlled genes concerned with the metabolism of lactose in E. Coli. The lac operon was the first example of a group of genes under the control of an operator region to which a lactose repressor binds. When the bacteria are transferred to lactose containing medium, allolactose (which forms by transglycosylation when lactose is present in the cell) binds to the repressor, inhibits the binding of the repressor to the operator and allows transcription of mRNA for enzymes involved in galactose metabolism and transport across the membrane (_ galactosidase, galactoside permease and thiogalactoside transacetylase). (18 Nov 1997) |
| lactose permease | <chemical> Chemical name: permease, lactose Synonym: lactose carrier protein, lactose permease m protein, lac permease, lactose transport protein, lactose transport system, lac carrier protein, lacs protein, lactose transport system, streptococcus thermophilus, lacy protein (26 Jun 1999) |
| lactic acidosis |
High levels of lactic acid in the blood, which is potentially fatal. Symptoms include nausea, vomiting, fatigue, and shortness of breath. The use of nucleoside analogs can contribute to lactic acidosis.
