Biochemistry is the branch of chemistry with the study of all chemical reactions that occur in living organism
Size Exclusion Chromatography In size exclusion chromatography ( molecular or gel filtration or gel permeation chromatography), molecules, and particles are separated. Small molecules penetrate the pores of the stationary phase, but large molecules do not. Because small molecules must pass through an effectively larger volume, large molecules are eluted first. This technique is widely used…
The most important chemical reactions ofmonosaccharides are: Furfural formation: Sugar loses water when heated with acid substances (H2SO4 or HCl) and generates furfural derivatives. It is also known as the dehydration of monosaccharides. Thus hexose gives hydroxymethyl furfural while pentose gives furfural on dehydration. This furfural can condense with phenolic compounds (α- naphthol) to form…
What are Proteins? Proteins consist of linear sequences of amino acids that are connected by peptide bonds. The arrangement of these amino acids carries the information needed to a protein molecule with a distinctive three-dimensional structure. The 20 amino acids commonly found in proteins are connected together by peptide bonds. On a chemical basis: Proteins…
SCOPE OF CHEMISTRY Everything around us deals with chemistry. When we say a thing like a scope, we come to know that it’s a branch of science that is as old as mankind, and at the same time, it went through the evolution phases just like human beings. From the atmosphere to the sea, plants to…
Definition: Lipids are the organic compounds that can be obtained from cells and tissues by non-polar organic solvents. Lipids are not polymers. Lipids are insoluble in water but they are soluble in organic solvents like benzene, carbon tetrachloride, ether and acetone. Although they dissolve in all organic solvents; but highly soluble in non-polar organic solvents….
The compound has an identical molecular formula but It contains different structures is called isomerism. Here will discuss the isomerism of carbohydrates. Types of Isomerism: Ketose-aldose isomerism: Glucose and fructose are isomers of each other having the same chemical formula “C6H12O6, but they differ in structural formula concerning their functional groups. There is a keto…
Polysaccharides: Carbohydrates are composed of ten or more monosaccharides units held together by glycosidic bond is called polysaccharides. These are colloidal in size. It is known as “glycans” .These are classified in two groups Homo polysaccharides: These polysaccharides is made up of several units of one and same type of monosaccharides unit only …
