RB011 - Benedict's qualitative reagent
Click to download Document.
Guidance on how to prepare Benedict’s qualitative solution. This is used to qualitatively test for reducing sugars e.g. glucose, via a colour change.

PP011 - Testing for carbonyl compounds with Fehling's solution
Click to download Document.
Although both aldehydes and ketones contain the carbonyl functional group (-C=O), only aldehydes give a positive test (formation of an orange to brick-red precipitate of copper(I) oxide) with Fehling’.. more

PP157 - Investigating aspects of carbohydrate structure through selective enzyme action
Click to download Document.
This protocol explores the effects of different carbohydrase enzymes on a range of carbohydrates of varying molecular size by measuring the resulting concentrations of reducing sugars using a colorime.. more

PP158 - Visking tubing model of the gut using starch and amylase
Click to download Document.
This protocol uses starch and amylase, contained within Visking tubing, to model the action of the gut. It includes both a simplified method, which demonstrates starch digestion and the production of .. more

RB076 - Sandell's solution
Click to download Document.
Guidance on how to prepare Sandell's solution. This reagent may be used to test for aldehydes and is a safer alternative to Fehling's for testing for reducing sugars.

PP012 - Testing for carbonyl compounds with Tollen's reagent
Click to download Document.
Although both aldehydes and ketones contain the carbonyl functional group (-C=O), only aldehydes (or reducing sugars) give a positive ‘silver mirror’ test result with Tollen’s reagent. This small-scal.. more

PP150 - Paper chromatography of reducing sugars
Click to download Document.
A simple method for identifying reducing sugars using chromatography. The reducing sugars need to be stained with Benedict’s reagent to reveal the spots after the run.
