Schiff test - Wikipedia, the free encyclopedia The Schiff test is an early organic chemistry name reaction developed by Hugo Schiff,[1] and is a relatively general chemical test for detection of many organic aldehydes that has also found use in the staining of biological tissues.[2] The Schiff reagent
INTRODUCTION 1.1 General Introduction of Schiff bases 5 to give the secondary amines (R2NHR3). Because of the involvement of Schiff base hydrolysis in a number of enzyme mediated processes, the detailed mechanism of hydrolytic cleavage of carbon-nitrogen double bonds has been the subject of close scrutiny ..

20.3 the Pentose Phosphate Pathway Generates NADPH and Synthesizes Five-Carbon Sugars - Biochemistry The pentose phosphate pathway meets the need of all organisms for a source of NADPH to use in reductive biosynthesis (Table 20.2). This pathway consists of two phases: the oxidative generation of NADPH and the nonoxidative interconversion of sugars (Figur

Identification of an Unknown – Alcohols, Aldehydes, and Ketones 3 and not a ketone. Note that generally, more extended systems of conjugation lead to colored compounds. Whereas the Schiff reagent itself has a limited system of conjugation, the adduct with an aldehyde has an extended system of conjugation, resulting in
