Reaction with alcohol. The glycosidic OH group of mutarotating sugars react with alcohols to form αand βglycosides or acetals. Thus, glucose forms glucosides and fructose forms fructosides. The glucosides, or glycosides in general, do not exhibit mutarotation as the aldehyde group in them is converted to the acetal group. A number of glycosides occur in nature, e.g., phlorhizin (glucose + phlor...

Cyanide is highly toxic Cyanide is one of the most toxic chemical substances on Earth. Cyanide is toxic to most aquatic life and humans, even at low concentrations. Its use in gold mining is controversial. The extreme toxicity of cyanide arises from its readiness to react with other elements and hence interfere with normal biological processes. Cyanide gas is a biological weapon and was used in...

Material and Methods Specific IgE for 20 common foods in 432 Romanian adults were evaluatted by MAST in sera. The patients were submited to our allergy department for urticaria (278 pts) and respiratory allergy (rhinits and/or asthma) (154 pts). We evaluated the presence of specific IgE to 20 foods. The foods evaluated were: hazelnuts, peanuts, walnuts, almonds, cow’s milk protein (casein and l...
