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.

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.

DEF

A chemical compound having the formula CHN or HCN or HNC which appears under the form of a flammable, toxic water-white liquid at temperatures below 26.5°C, with a faint odour of bitter almonds, which occurs naturally in some plants (almond, oleander), usually combined as glycosides (as amygdalin) and also in coke-oven gas, which can be synthesized from ammonia and carbon monoxide, and which is used in the manufacture of acrylonitrile, acrylates, adiponitrile, cyanide salts, dyes, chelates, rodenticides and pesticides.

CONT

The metabolism of sugars and starch, in plant development and growth via the phytohormones-glucoconjugated forms, the regulation of the structure/organization of membranes, in defensive metabolism against herbivorous pathogens, via the release of a respiratory poison from the hydrolysis of ß-glucosides of cyanogenic acids, hydroxamic acids, steroïds, isoflavonoïds, saponins, homoterpenes and indo-alkaloids, in secondary metabolism of flavonoïds, lignins and stilbenes, and in circadian rate/rhythm of leaves movements ...

Liquide incolore, très volatil et possédant une odeur caractéristique dite prussique d'amandes amères.

CONT

Les rôles physiologiques des ß-glucosidases sont nombreux et sont liés à la nature et à la fonction des aglycones qu'elles libèrent. En effet, certains aglycones devenus actifs après hydrolyse de leurs glucosides conjugués jouent un rôle important dans divers mécanismes métaboliques : [...] (4) dans le métabolisme de défense contre les pathogènes et herbivores, via la libération d'un poison respiratoire à partir de l'hydrolyse des ß-glucosides des acides cyanogéniques, des acides hydroxamiques, stéroïdiens, d'isoflavonoïdes, de saponines, d'homoterpènes et d'indo-alcaloïdes.

Approach used for the laboratory preparation of immobilized enzyme derivatives as well as for insoluble adsorbents for affinity chromatography. It is based on the activation of water-insoluble polysaccharides, cellulose, cross-linked dextran, and agarose, with cyanogen bromide.... The polysaccharide is activated with cyanogen bromide at high pH (10-11.5). Compounds containing free amino groups, including peptides and proteins, can then be attached covalently to the activated polymer at mildly alkaline pH values.
