Cellular Respiration- Definition, Equations, Types, Steps, Products

Cellular Respiration

Cellular Respiration Definition Cellular respiration is a metabolic process consisting of a series of steps to convert chemical energy (sugar) into a usable form of energy (ATP) in the cell. The reactions involved in cellular respiration are catabolic reactions that involve the breakdown of larger organic molecules into smaller forms. The overall process of cellular respiration takes place in a …

Xanthoproteic Test- Definition, Principle, Procedure, Result, Uses

Xanthoproteic Test

Xanthoproteic Test Definition Xanthoproteic test is a biochemical test for the detection of amino acids containing phenolic or indolic groups like phenylalanine, tyrosine, and tryptophan (aromatic amino acids). The test is named Xanthoproteic test due to the formation of a yellow precipitate of xanthoproteic acid. The term ‘Xantho’ refers to ‘yellow’, so the test is often termed as the Yellow …

Sullivan and McCarthy’s Test- Definition, Principle, Procedure, Result, Uses

Sullivan and McCarthy’s Test

Sullivan and McCarthy’s Test Definition Sullivan and McCarthy’s test is a biochemical test for the detection of the amino acid methionine or methionine-containing proteins. The test is a specific test for methionine which has a high degree of specificity towards methionine as it gives negative results with all other amino acids. The test, however, gives a positive result with glycylmethionine. …

Solubility Tests of Proteins- Definition, Principle, Procedure, Result, Uses

Solubility Tests of Proteins

Solubility Tests of Proteins Definition Solubility tests are tests performed to determine the ability of compounds to dissolve in a solvent, which is usually a liquid. These tests are essential to determine the size and polarity of unknown compounds and the presence of acidic and basic functional groups. Solubility tests for proteins and amino acids are qualitative tests that determine …

Salt Saturation Test- Definition, Principle, Procedure, Result, Uses

Salt Saturation Test

Salt Saturation Test Definition Salt Saturation Test is a test for the precipitation of proteins and their differentiation from other proteins by using the salting-out technique. Salting out is the process of precipitation of proteins by increasing the concentration of salt in the solution. The salts used in this technique are mostly neutral mineral salts like MgSO4, Na2SO4, and (NH)2SO4. …

Pauly’s Test- Definition, Principle, Procedure, Result, Uses

Pauly’s Test

Pauly’s Test Definition Pauly’s test is a biochemical test for the detection of tyrosine and histidine where the reagent couples with amines, phenols, and imidazole groups. The test was discovered by and is named after the German Chemist Hermann Pauly. Pauly’s test is a specific test for proteins containing tyrosine and histidine as the reagent undergoes diazotization with aromatic groups. …

Nitroprusside Test

Nitroprusside Test Definition Nitroprusside test is a biochemical test used for the detection of the free –SH groups in amino acids or the cysteine amino acid in a protein. The test is a specific test for cysteine as it is the only amino acid with a free –SH group in the structure. The test, however, is not specific to proteins …

Millon's Test

Millon’s Test Definition Millon’s test is an analytical test used for the detection of the amino acid tyrosine, which is the only amino acid containing the phenol group. Millon’s test is a specific test for tyrosine, but it is not a specific test for protein as it also detects the phenolic group present in other compounds as well. Therefore, while …
