The ninhydrin and biuret reactions are used to detect amino acids and peptides. These reactions are experimentally effective, because vivid color changes are observed in short times. Accordingly, we ...

Two simple and sensitive spectrophotometric methods are described for the determination of lisinopril in pure form and pharmaceutical preparations. The first method is based on the reaction of the ...

A new class of fluorescent dyes can instantly visualise hidden fingerprints at crime scenes. Compared with traditional chemical reagents used for detecting latent fingerprints, the fluorescent dyes ...

We used a chemical called ninhydrin to chop off and isolate the carbon atom we wanted from each amino acid. We then sent these carbon atoms – from a very metabolically active part of the amino acid ...

Ninhydrin, 2,2-dihydroxyindane-1,3-dione (Figure 1b) is a known chromogen, that reacts with primary amines or amino compounds - this includes amino acids, peptides, proteins, and even ammonia ...

HYDERABAD: The CBI on Wednesday got the nod from the CBI court, Hyderabad, to proceed further in conducting ninhydrin test on the letter written by Y.S. Vivekananda Reddy, before his death. The ...

HYDERABAD: The CBI, which is probing the murder of Y.S. Vivekananda Reddy, approached the CBI court here on Friday seeking the court’s nod to run a ninhydrin test on the letter retrieved from ...

ABSTRACT: A simple, precise, inexpensive and reproducible spectrophotometric method was investigated for the determination of chromium ion (III) in aqueous media, this method based on the formation of ...
