QUÉ SIGNIFICA CYANOGENESIS EN INGLÉS
Cianuro
Un cianuro es cualquier compuesto químico que contiene el grupo de combinación monovalente CN. Este grupo, conocido como el grupo ciano, consiste en un átomo de carbono unido triples a un átomo de nitrógeno. En cianuros inorgánicos, tales como cianuro sódico, NaCN, este grupo está presente como el ion cianuro poliatómico cargado negativamente; Estos compuestos, que se consideran sales del ácido cianhídrico, son altamente tóxicos. El ion cianuro es isoelectrónico con monóxido de carbono y con nitrógeno molecular. La mayoría de los cianuros son altamente tóxicos. Los cianuros orgánicos se llaman generalmente nitrilos; En éstos, el grupo CN está unido por un enlace covalente a un grupo que contiene carbono, tal como metilo en cianuro de metilo. El ácido cianhídrico, también conocido como cianuro de hidrógeno o HCN, es un líquido muy volátil utilizado para preparar acrilonitrilo, que se utiliza en la producción de fibras acrílicas, caucho sintético y plásticos. Los cianuros se emplean en una serie de procesos químicos, incluyendo fumigación, endurecimiento de hierro y acero, galvanoplastia y concentración de minerales. En la naturaleza, las sustancias que producen cianuro están presentes en ciertas semillas, como el pozo de la cereza silvestre.
definición de cyanogenesis en el diccionario inglés
La definición de cianogénesis en el diccionario es la liberación de ciertas plantas, como el laurel de cereza, el cianuro de hidrógeno, especialmente después de heridas o la invasión de patógenos.

Cyanide Compounds in Biology
The polymorphism for cyanogenesis in Lotus corniculatus and Trifolium repens
provides ample evidence that cyanogenesis has an important role in plant
defence. This herbivore-plant interaction is, however, far from simple: the degree
of ...

Plant Variation and Evolution
It is not possible to summarise all the results discovered in experiments, but they
suggest that a number of interacting factors may influence patterns of
cyanogenesis, for there is evidence that water stress, mammal grazing, trampling,
insect ...

Toxic Plants of North America
several species of Trifolium are reported to be cyanogenic (Table 35.13),
cyanogenesis is a rare consequence of ruminants grazing T. repens late in a
growing season when rainfall has been poor or erratic (Coop 1949; Vickery et al.

Bioactive Compounds from Plants
In herbs, variations in the palatability of leaves are also apparent, notably in the
case of cyanogenesis. Cyanogenic glycosides are bitter tasting and such plants
are normally rejected, quite apart from their poisonous nature. The expression of

Herbivores: Their Interactions with Secondary Plant ...
As early as 1966, Jones (1966) indicated that cyanogenesis polymorphisms in
legumes may be useful in determining the importance of herbivores as selective
agents on plant chemistry and in ascertaining the significance of plant chemistry
in ...

Plant Secondary Metabolism
The ability to produce cyanide or Cyanogenesis has long been recognized in
plants. At least 2650 species, from more than 550 genera, and 1 30 families
possess the ability to make Cyanogenic glycosides (Hegnauer, 1986; Seigler,
1991).

Introduction to Ecological Biochemistry
The reason why cyanogenesis is high in British populations is probably because
the high winter isotherm means that predators like slugs and snails are active all
the year round. When clover and the trefoil start germinating in the spring, the ...

Genetic and Evolutionary Diversity: The Sport of Nature
9.3 CYANOGENESIS IN PLANTS The Victorian hero General Charles Gordon
was besieged in Khartoum by the Mahdi in 1884/85. As if there were not enough
other problems, his horses began to die with symptoms of cyanide poisoning.

Annual Plant Reviews, Biochemistry of Plant Secondary Metabolism
Many publications report that this enzyme is involved in cyanogenesis upon
tissue disruption (Kojima et al., 1979; Conn, 1981), but, in contrast to the
intensive investigation of B-glucosidases, only a few papers have dealt with
HNLs. This may ...
