Carbohydrates are the most abundant biological molecules, and are widely distributed in nature.They can be isolated from plants, animals, bacteria and fungus as molecules of low molecular weight, oligosaccharides or as polymers.Knowledge of the qualitative and quantitative distribution of sugars in natural materials, specially the related with food chain and human health, is extremely important because sugars are one of principal food constituents: they are involved in food authenticity, nutritional characteristics (as flavor and sensory) and, for example, they are constituents of natural antibiotics (like streptomycin and puromycin).Carbohydrates and their derivatives are also important as biological keys in all metabolisms of living organisms, in the storage and transport of energy, and are present as structural components.
