UseUses: Used as an analytical reagent to identify amino acids, proteins, peptides, vitamin C, etc. It can also be used in organic synthesis. Avoid contact with skin to avoid skin redness. Ninhydrin test solution(ChP) -Uses and synthesis methods ...
Triketohydrindene Clinical toxicology An oxidizing reagent that reacts with amino acids and proteins, used to screen urine specimens for presence of, and semiquantify, α-amino acids, as it changes colors McGraw-Hill Concise Dictionary of Modern Medicine. © 2002 by The McGraw-Hill Companies, ...
SINCE the work of Berg 1 , the ninhydrin reaction has been commonly used as a histochemical test for the 伪-amino-acid groupings of proteins. The reaction of proteins with alloxan, giving rise to murexide, has already been criticized by Romieu 2 for lack of specificity and by Giroud 3 ...
A lithium acetate-dimethyl sulfoxide ninhydrin reagent was shown to be useful for reaction of amino groups in a series of structurally diverse food proteins and flours of variable lysine content. The proteins were bovine serum albumin, casein, hemoglobin, lactalbumin, lysozyme, soybean protein, soybea...
Ninhydrin can be used as a chromogenic analytical probe for the quantification of amino acids and proteins. Names Nameninhydrin SynonymMore Synonyms Ninhydrin Biological Activity DescriptionNinhydrin can be used as a chromogenic analytical probe for the quantification of amino acids and proteins. ...
A ninhydrin histochemical test specific for hair keratin The reaction of ninhvdrin with 伪-amino groups of amino acids and proteins results in deamination of the amino acid or protein to form a nitrogen-containing blue dye complex. This molecule is small and highly diffusible, a property which....
Ninhydrin test isused to detect the presence of amino acids in unknown samples. This test is also used in solid-phase peptide synthesis to monitor the protection for amino acid analysis of proteins. As the ninhydrin test is quite sensitive, it is commonly used to detect fingerprints. ...
is the primary means of quantitative identification of amino groups in colorimetry and spectrophotometry. The ninhydrin reaction is also used to detect secondary amino groups (> NH) in imino acids (proline and hydroxyproline); a bright yellow product is obtained as a result of the test. ...
Polypeptides and proteins did not produce a yellow chromophore. Evidence is provided for a reaction sequence in which peptides first react with Cu 2+ to form a complex which then reacts with ninhydrin to give the yellow chromophore. These results and also studies with several peptides having N...
The analysis of ninhydrin reactive nitrogen (NRN: ammonium and organic amines) is helpful in the investigation of the decomposition process, because such products may result from degradation of proteins and amino acids. During this research a new application form of the well known ninhydrin reagent ...
