Antibiotics: History, mechanism, and Uses
Antibiotics, popularly known as antibacterials are used to treat or prevent some types of bacterial infections. However, it doesn’t work for viral infections like cold and flu, sore throat, etc. Penicillin, the first ever accidentally discovered antibiotic brings a new revolution to the field of medicine. Various types of antibiotics classes are: Among all the […]
Banana peels: A waste treasure for Humans
Banana peels, the outer covering of bananas though being discarded as waste, are very useful in terms of purification of water, food for animals, ingredients for gardening, cosmetics, cooking, household cleaning, and so on. Every time we peel a banana and discard the skin, we are throwing away delicious food that is packed with nutrients […]
Chemistry of e-waste: Bad effects
This post is related to the e-wastes generated from different electrical devices and technologies, and their adverse effect on human health and environments. Chemistry of e-waste With the rapid advancement of technology, electronic appliances have become an inseparable part of daily life. Their use is increasing day by day. But what happens to those electronic […]
Osazone Formation Mechanism
Osazone is the derivative of carbohydrates that are formed by the reaction of carbohydrates with phenylhydrazine. As aldehyde, aldoses react with phenylhydrazine to form phenylhydrazones. In 1875, Emil Fischer found that reducing benzene diazonium chloride by sulfur dioxide yields phenylhydrazine. Fischer reported that the phenylhydrazine he had discovered could be used as a powerful tool […]
Detection of Carbohydrates and glycosides: Detection of functional group
The word carbohydrates are derived historically from the idea of “hydrates of carbon,” the general formula Cn(H20)n; for example, glucose has the formula C6H1206. Sucrose (common table sugar) isconsistent with another general formula, Cn(H20)m, because it has the formula C12(H20)11. Glucose, cellulose, starch, and glycogen all belong to the class of organic compounds known as […]
Detection of Ketones: Detection of functional group
Ketones are organic molecule that contains a functional group with the formula RCOR. These are neutral compound contain reactive carbonyl compound. In most reaction aldehydes are more reactive than ketones. Test for Ketones Many of the same reactions that are described in the classification of aldehydes can also be used to classify ketones. Iodoform test […]
Detection of Aldehyde: Detection of functional group
An aldehyde is an organic molecule that contains a functional group with the formula RCH=O. These are neutral compound contain reactive carbonyl compound. In most reaction aldehydes are more reactive than ketones. Test for Aldehydes Schiff’s reagent test Add 2 ml schiff’s reagent (Rosaniline hydrochloride decolorised with SO2) to 2 ml of liquid substance or […]
Detection of Carboxylic acid; Functional group detection
An organic acid with a carboxyl group (C(=O)OH) linked to an R-group is known as a carboxylic acid. A carboxylic acid has the general formula RCOOH or RCO2H, where R refers to the alkyl, alkenyl, aryl, or other group. Amino acids and fatty acids are two important examples of carboxylic acid. Test for carboxylic acid Carboxylic […]
Detection of foreign elements
Detection of foreign elements is important for locating the class of organic compounds. Organic compounds have been classified into various types, depending upon the elements present in them. All organic compounds are expected to contain carbon and hydrogen, so it is not necessary to test for the presence of these elements. Detection of Nitrogen, Sulphur, […]
Chemistry of vision
Chemistry of vision is something beautiful that occurs in presence of light and human eyes can detect a very low amount of light absorbed by rod cells. The retina of a mammal contains rod cells. In rod cells, a conjugated protein is present, known as rhodopsin. The rhodopsin has a prosthetic group called 11-cis retinal. […]
