In chemistry, cyanide (from Greek kyanos 'dark blue') is a chemical compound that contains a C≡N functional group. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom. [1] In inorganic cyanides, the cyanide group is present as the cyanide anion − C≡N. This anion is extremely poisonous.
The blood of people killed by blood agents is bright red, because the agents inhibit the use of the oxygen in it by the body's cells. [2] Cyanide poisoning can be detected by the presence of thiocyanate or cyanide in the blood, a smell of bitter almonds, or respiratory tract inflammations and congestions in the case of cyanogen chloride ...
A blood type (also known as a blood group) is a classification of blood, based on the presence and absence of antibodies and inherited antigenic substances on the surface of red blood cells (RBCs). These antigens may be proteins , carbohydrates , glycoproteins , or glycolipids , depending on the blood group system.
Cyanogen is typically generated from cyanide compounds. One laboratory method entails thermal decomposition of mercuric cyanide: . 2 Hg(CN) 2 → (CN) 2 + Hg 2 (CN) 2 Or, one can combine solutions of copper(II) salts (such as copper(II) sulfate) with cyanides; an unstable copper(II) cyanide is formed which rapidly decomposes into copper(I) cyanide and cyanogen.
Hydrogen cyanide (formerly known as prussic acid) is a chemical compound with the formula HCN and structural formula H−C≡N.It is a highly toxic and flammable liquid that boils slightly above room temperature, at 25.6 °C (78.1 °F).
Based on this he classified human blood into three groups, namely group A, group B, and group C. He defined that group A blood agglutinates with group B, but never with its own type. Similarly, group B blood agglutinates with group A. Group C blood is different in that it agglutinates with both A and B. [9]
Doctors explain which blood type is more susceptible to norovirus, also known as the 24-hour flu and stomach bug. Plus, how one gene mutation helps protect from it. ... “Blood group and secretor ...
A blood diagnostic reported a lethal level of cyanide in his blood, but the body did not display any classic symptoms of cyanide poisoning, and no link to cyanide could be found in Urooj's social circle. The diagnostic method used was the Conway diffusion method, prone to false positives with artifacts of heart attack and kidney failure.
