Carbohydrates H2SO4 acts as dehydrating agent forming furfural derivatives which interact with alpha-naphthol librating a violet layered compound Test | Molisch test | Objective | A general test for all carbohydrates. Monosaccharides give a rapid positive test. Disaccharides and polysaccharides react slower. | Principle involved | Dehydration of the carbohydrate by concentrated sulfuric acid to produce an aldehyde | Reagent | H2SO4 | Positive results | a purple-black layer/violet ring

January 1999 B io Factsheet Example glucose fructose galactose Number 39 Carbohydrates: Revision Summary Carbohydrates contain 3 elements: Carbon (C)‚ Hydrogen (H) and Oxygen (O). Thus‚ if we remove water from carbohydrates‚ all that remains is carbon. Carbohydrates can be divided into 3 categories; monosaccharides‚ disaccharides and polysaccharides (Table 1). Table 1. Structure of monosaccharides‚ disaccharides and polysaccharides Category Monosaccharide (made of 1 sugar molecule)

Intro: Carbohydrate‚ any of a large group of compounds in which hydrogen and oxygen‚ in the proportions in which they exist in water‚ are combined with carbon; the formula of most of these compounds may be expressed as Cn(H2O)n. Structurally‚ however‚ these compounds are not hydrates of carbon‚ as the formula would seem to indicate. Carbohydrates‚ as a class‚ are the most abundant organic compounds found in nature. They are produced by green plants and by bacteria using the process known as photosynthesis

The structural features of carbohydrates account for the fact that a wide variety of polysaccharides exist is pentoses and hexoses. The examples of pentose are ribose‚ deoxyribose‚ ribulose and xylulose. The examples of hexose are glucose which is found in fruits‚ fructose which is found in milk and galactose which is found in honey. Both pentoses and hexoses are mostly found in monosaccharides. They are the most simplest sugar which cannot be futher hydrolysed into smaller units. They contain
