Carbohydrates: compounds of high importance, provide energy through oxidation, supply carbon for the synthesis of cell components, they serve as a form of stored energy, form part of the structures of some cells an tissues. Solids at room temperature: extremely soluble in water. Sugar chemist = carbohydrate, formula ch2o: many chemicals included in this category. Sugar consumer the specific sugar sucrose: 2 units (disaccharide): glucose-fructose, monosaccharides: glucose, fructose, note terminology can get confusing here mixture of chemical and colloquial terms, glucose = d-glucose = dextrose, glucose = c6h12o6. Sucrose: naturally occurring carbohydrate, fruits and vegetables, sugar cane and sugar beets, table sugar, does not occur in milk but may be used to sweeten milk products. Barley: germinating barley contains malt, comes from endosperm, almost pure maltose. Generalized sugar processing: collect plant sap directly or by crushing.
