protein molecular weight determination

Proteins - Proteins are the chief body builders of the body. They are complex molecules made up of carbon, hydrogen, oxygen and nitrogen (sometimes sulphur and phosphorus). Proteins are used to synthesize enzymes (e.g., pepsin, trypsin), hormones (e.g., insulin, adrena..

Proteins are made up of amino acids. Proteins are in the form of one or more chain called polypeptide chains. Within the polypeptide chains, the amino acids and amides are linked through peptide bonds, involving the carboxyl group of one amino acid and the amino group of the nex..

Proteins - Introduction - Proteins are the high molecular mass complex biopolymers of amino acids and organic compounds that are most important to life. They are essential for growth and maintenance of life. They are high molecular weight, nitrogen ..

In order to determine the molecular mass of unknown non volatile compound, a known mass (say w g) of the compound is dissolved to prepare a known volume (say v liters) of solution. The osmotic pressure of the solution is determined and the molar mass is calculated as f..

Gram molecular weight (GMW) or mole is the relative molecular mass of a substance expressed in grams. It is also called gram molecular weight of that element. Gram molecular volume (GMV) or molar volume is the volume occupied by one-gram h..

Gram molecular weight (GMW) is the relative molecular mass of a substance expressed in grams. It is also called gram molecule of that element. Gram molecular volume (GMV) or molar volume, is the volume occupied by one gram molecular weight..

The molecular mass of a compound is essential to determine its molecular formula. Molecular mass of an organic compound is determined by a number of metho..

Avagadro's law helps us to determine the molecular formula of gases like ammonia, carbon dioxide, sulphur dioxide etc. Exampl..

Silver salt method is used for determining the molecular masses of carboxylic acids. This method is based on the fact that they form insoluble silver salts, which upon heating decompose to leave a residue of metallic silve..

Example: 21 - An organic compound has the following percentage composition: C= 40%, H = 6.66%, O = 53.33%. Find its molecular formula (Relative atomic mass of C=12, H=1, O=16 and Relative molecular mass of the compound = 18..
