GLUCOSIDE [8 records]

Record 1 2025-04-22

English

Subject field(s)
  • Chemical Elements and Compounds
  • Plant and Crop Production
  • Biochemistry
CONT

cyanogenic: [Said of] compounds able to produce cyanide; examples are the cyanogenic glycosides such as amygdalin in peach and apricot stones.

CONT

Cyanogenic glycosides are present in a number of food plants and seeds. Hydrogen cyanide is released from the cyanogenic glycosides when fresh plant material is macerated as in chewing, which allows enzymes and cyanogenic glycosides to come together, releasing hydrogen cyanide.

OBS

glycoside: Any of a class of compounds, many of which are present in plants, which on hydrolysis give a sugar and one or more other compounds, one of which is usu. an alcohol or a phenol.

OBS

glucoside: One of a class of vegetable substances which being treated with dilute acids or alkalis, or subjected to the action of ferments, are resolved into a sugar and some other substance. Now usually restricted to mean a glycoside which on hydrolysis gives glucose.

Key term(s)

DEF

Glycoside qui libère du cyanure d'hydrogène.

CONT

cyanogène; cyanogénique : [Se dit d'un] composé capable de produire du cyanure; par exemple, les glycosides cyanogènes, telle que l'amygdaline des noyaux de pêche et d'abricot.

CONT

Les racines de manioc (Manihot esculenta) contiennent en effet des quantités plus ou moins importantes, selon les variétés, de glycosides cyanogénétiques - linamarine et lautostraline -, qui sont des substances toxiques puisqu'elles libèrent de l'acide cyanhydrique.

CONT

La linamarine est un glucoside cyanogénétique qui est transformé en acide cyanhydrique toxique ou acide prussique lorsqu'il entre en contact avec la linamarase, une enzyme qui est libérée quand les cellules des racines de manioc se rompent.

English

Subject field(s)
  • Chemical Elements and Compounds
  • Biochemistry
DEF

One of a group of organic compounds, of abundant occurrence in plants which can be resolved by hydrolysis into sugars and other organic substances known as aglycones.

OBS

glycoside: This term is considered by some authors a synonym for "heteroside", defined as a "glycoside which, on hydrolysis, yields a noncarbohydrate as well as a glycose." By comparison, a "glycoside" is an acetal derivative of sugar which on hydrolysis (as by the action of enzymes or dilute acids) yields one or more molecules of a sugar and OFTEN a noncarbohydrate.

OBS

Specifically glycosides are acetals which are derived from a combination of various hydroxy compounds with various sugars. They are designated individually as glucosides, mannosides, galactosides, etc. Glycosides were formerly called "glucosides", but the latter term now refers to any glycoside having glucose as its sugar constituent.

The drug St. John's wort consists of the dried above-ground part of "Hypericum perforatum L", collected shortly before or during the flowering period. It contains not less than 0.04% naphthodianthrones of the hypericin group (so-called total hypericin). ... Other possible active ingredients are polymerization products of hypericin, the flavonoids quercetin, hyperoside, quercitrin, isoquercitrin, rutin, campherol, luteolin, and 13-118-biapigenin, the total concentration of which can amount to 2% to 4%.

CONT

... we have compared the bioactivities of the two most abundant flavonoid glycosides that we have purified from onions (quercetin-3,4'-diglucoside and quercetin-4'-glucoside) to the quercetin aglycone, and also to the more commonly studied commercially-available flavonoid glycosides, rutin (quercetin-3-rutinoside) and isoquercitrin (quercetin-3-glucoside).

English

Subject field(s)
  • Medication
DEF

Drug which increases the contractility of the heart muscle. The most commonly used glycosides acting on the heart are obtained from the leaves of Digitalis purpurea and lanata, from the seeds of Strophantus kombé and gratus, and also from the squill. Cardiac glycosides act by raising the concentration of calcium ions available intracellularly for electromechanical coupling. They thus exert a positive inotropic effect on the healthy, the hypertrophied, the still adequate, and the failing heart.
