Glycine is a sweet-tasting amino acid obtained from the hydrolysis of protein. It is a nonessential amino acid present in mammals. Mammals can synthesize glycine from the amino acids serine and threonine, and it is also present in certain animal … Read more
The mass spectrometer is generally designed to perform three basic functions, they are: Instrumentation of Mass Spectrometry (MS) Sample handling system The sample handling system is used to introduce the sample into the ion source at low pressure. Heating is … Read more
Polymer is composed of two Greek words (i.e., poly= many and mer= simple unit). So, polymers are large molecules (macromolecules) formed by the combination of simple units. The simple compounds from which polymers are formed are called monomers. Name of … Read more
Mass spectroscopy is the accurate method for determining of molecular mass of the compound and its elemental composition. Principle of Mass Spectroscopy When molecules are bombarded with an energetic electron beam, 1e- is removed from the molecule. The removal of … Read more
UV spectroscopy involves the promotion of electrons (n, σ, Ï€) from the ground state to a higher energy state. In U.V. spectroscopy, the excitation of the electron occurs in the range of 200-800 nm. Principle of UV Spectroscopy When the … Read more
Infrared spectroscopy is the measurement of the interaction of IR radiation with compounds. IR region involves the range between region 400-4000 cm-1. IR radiation causes the excitation of molecules from lower to higher vibrational levels. These vibrational levels are associated … Read more
Carboxylic acids are the organic compounds containing the carboxyl group (-COOH) as a functional group. The general formula is: The name carboxyl is obtained from carbonyl (-CHO) and hydroxyl (-OH) as in the carboxyl group carbonyl and hydroxyl group are … Read more
Esters are the derivatives of carboxylic acids containing -COOR as a functional group, in which the -OH group of a carboxylic acid is replaced by the -OR group. Esters are important derivatives of an acid. The ester of a carboxylic … Read more
Aldehyde and ketones are commonly known as carbonyl compounds. Both aldehyde and ketone consist of a carbon-oxygen double bond as a functional group. Which is known as the carbonyl group. The carbonyl group in an aldehyde is bonded to one … Read more
