Amygdalin (Figure 1.13(A)) is present in the almond fruits of Prunus dulcis. Its name is derived from the ancient Greek word for “almond.” There are two varieties of almonds, one that tastes sweet (variety dulcis) and one that is bitter (variety amara, also called bitter almond). In...
Toxicological analysis of cyanide and interpretation of cyanide concentrations in blood and other tissues is fraught with difficulty. Not only are small concentrations of cyanide present in normal blood but cyanide can accumulate in stored samples of blood. However, even in ideal storage situations, cy...
In the present theoretical study, we identified two prominent precursors for the building up of RNA and DNA nucleobases under prebiotic conditions: (a) 1,2-diaminomaleonitrile (DAMN), which is a tetramer of hydrogen cyanide (HCN), ... YA Jeilani,PN Williams,S Walton,... - 《Physical Chemi...
A volumetric procedure is described for the micro-determination of cyanide. Small amounts of cyanide can be estimated even in presence of chloride if it is present in the electrolytic bath. N-Bromosuccinimide (NBS) is used to quantitatively oxidized cyanide to cyanate. The end point is reached ...
is somewhat reduced if alcohol and sugar are present simultaneously with the cyanide. The reason is that the cyanide ion can react with the sugars to form amygdalin. This compound is not very stable and decomposes in water to reform cyanides and sugar. (Hydrolysis). Anecdotally, when attempts...
Cyanide is commonly found in soils and groundwater complexed with iron as ferro- and ferri-cyanide. It is evident that plants are capable of tolerating, transporting, and assimilating iron cyanides. The objectives of this study were to investigate the influence of temperatures on the removal and...
Cyanide from the cyanogenic glucoside linamarin is associated with the toxicity of cassava. Adverse effects from cyanide under acute conditions are well known, but reports of chronic toxicity have dealt mainly with tobacco amblyopia. Observations were made on the effects of dietary cyanide on urinary ...
Biological treatment of cyanide is a well-established process and has been commercially used at gold mining operations in North America. Biological treatment processes facilitate growth of microorganisms that are essential for the treatment. The present review describes the advances in the use of ...
