| lactic acid fermentation | <biochemistry> A type of fermentation carried out by lactic acid bacteria in which sugar (for example lactose, glucose, pentose) are converted either entirely (or almost entirely) to lactic acid (homolactic fermentation) or to a mixture of lactic acid and other products (heterolactic fermentation). (09 Oct 1997) |

| lactic acid level | <investigation> A test that measures the amount of lactic acid in the blood. (25 Jun 1999) |
| lactic acid oxidative decarboxylase | A flavoprotein oxidoreductase catalyzing oxidation (with O2) of l-lactate to acetate plus CO2 and water. Synonym: lactic acid oxidative decarboxylase. (05 Mar 2000) |
| lactic acidemia | The presence of dextrorotatory lactic acid in the circulating blood. Synonym: lactacidemia. Origin: Lactic acid + G. Haima, blood (05 Mar 2000) |
| lactic acidosis | <biochemistry, physiology> Acidosis caused by accumulation of lactic acid more rapidly than it can be metabolised. It may occur spontaneously or in association with diseases such as diabetes mellitus, leukaemia, or liver failure. (25 Jun 1999) |
| lactic dehydrogenase | <enzyme> The enzyme that catalyses the formation and removal of lactate according to the equation: pyruvate + NADH = lactate NAD. <cell culture> The appearance of lactic dehydrogenase in the medium is often usedas an indication of cell death and the release of cytoplasmic constituents. Acronym: LDH (25 Jun 1999) |
| lactide | <chemistry> A white, crystalline substance, obtained from also, by extension, any similar substance. Origin: Lactic + anhydride. Source: Websters Dictionary (01 Mar 1998) |
| lactiferous | Bearing or containing milk or a milky fluid; as, the lactiferous vessels, cells, or tissue of various vascular plants. Origin: l. Lac, lactis, milk: cf. F. Lactifere. Source: Websters Dictionary (01 Mar 1998) |
| lactiferous ampulla | A circumscribed spindle-shaped dilation of the lactiferous duct just before it enters the nipple. In nursing mothers this dilatation stores a droplet of milk which is expressed by compression as the infant begins to suckle; this is thought to encourage continual suckling while the let-down reflex ensues. Synonym: sinus lactiferi, ampulla lactifera, ampulla of milk duct, lactiferous ampulla. (05 Mar 2000) |
| lactiferous ducts | The ducts, numbering 15 or 20, which drain the lobes of the mammary gland; they open at the nipple. Synonym: ductus lactiferi, canalicular ducts, galactophore, galactophorous canals, galactophorous ducts, mamillary ducts, mammary ducts, milk ducts, tubuli galactophori, tubuli lactiferi. (05 Mar 2000) |
| lactiferous gland | <anatomy> Milk producing gland of female mammals. An adapted sweat gland, it is made up of milk producing alveolar cells, surrounded by contractile myoepithelial cells, together with considerable numbers of fat cells. Milk production is hormonally controlled. (18 Nov 1997) |
| lactiferous sinus | A circumscribed spindle-shaped dilation of the lactiferous duct just before it enters the nipple. In nursing mothers this dilatation stores a droplet of milk which is expressed by compression as the infant begins to suckle; this is thought to encourage continual suckling while the let-down reflex ensues. Synonym: sinus lactiferi, ampulla lactifera, ampulla of milk duct, lactiferous ampulla. (05 Mar 2000) |
| lactifugal | <medicine> A medicine to check the secretion of milk, or to dispel a supposed accumulation of milk in any part of the body. Origin: L. Lac, lactis, milk + fugare to expel. Source: Websters Dictionary (01 Mar 1998) |
