13 Μαΐ 2024 · The principle of Nylander’s Test revolves around the inherent chemical properties of certain carbohydrates, specifically those possessing an aldehyde group or a free ketone. In the realm of biochemistry, these functional groups play a pivotal role in the reaction mechanism of the test.
28 Φεβ 2020 · Take 5 ml sample solution in a test tube, add 5–8 drops of Nylander’s reagent, boil for 3 min on water bath, and cool. Observation. Black precipitates develop after a few minutes (bismuth subnitrate reduced to black bismuth).
Nylander's test is a chemical test used for detecting the presence of reducing sugars. Glucose or fructose reduces bismuth oxynitrate to bismuth under alkaline conditions.
