Carbohydrate (English version)

Carbohydrates are polyhydroxy aldehydes or polihidroksiketon and include the polymers formed condensate. Name of carbohydrates used in these compounds, given the empirical formula be CnH2nOn or approaching Cn (H2O)n, namely carbon which undergo hydration. However, this name is not appropriate because hydrate (H2O) which is attached to the carbon cluster is not as actual hydrate, for example, can not be separated or separate crystallized regardless of group.

In nature, carbohydrates are the synthesis of CO2 and H2O with the help of sunlight and green leaves (chlorophyll). The results of photosynthesis is then polymerized into starch and compounds other great molecule into plant food reserves. Organisms that can synthesize biomolecules for the purpose of his life from inorganic materials (such as CO2 and H2O) are called autotrophs organisms. While microorganisms in general, animals and humans are only able to use the results of the synthesis of autotrophs organisms for the purposes of his life called heterotroph organisms. Carbohydrates from the main source of calories or macronutrient heterotroph organisms. Some of them became the main ingredient of clothing (eg cotton fibers), Industry (hemp, roselle), building materials (wood, bamboo) or fuel (firewood, litter). Besides being a major source biokalori in foodstuffs, some types of carbohydrates and derivatives (derivatives) plays an important role in food technology eg gum (arabic, karaya, guar) as thickeners or CMC (carboxymethycellulose) as a stabilizer and many more as a sweetener (sucrose, glucose, fructose).
