Document Summary
Origin of the name: c6h12o6 = c6(h2o)6 hydrates of carbon. Plants produce glucose from carbon dioxide and water by using sunlight. Our body utilize the stored energy by demolition the compounds into co2. In the name, the suffix ose is used. Classification of carbohydrates: the compound can be aldose or ketose, the number of carbons is marked: tri-, tetr-, pent-, hex- or hept-. It has one chirality center a pair of enantiomer exists. One of the enantiomers rotate the plane-polarized light in the clockwise direction (+) or dextrorotatory (d). The other enantiomer rotate the plane-polarized light in the counterclockwise direction (-) or levorotatory (l). Naturally occurring carbohydrates can be decomposed into d-glyceraldehyde. D-sugars: carbohydrate enantiomer that occurs in nature. The oh group on the chirality center that is the farthest from carbonyl group is on the right in fisher projection. Have two chirality centers two pairs of enantiomers: d-erythrose, l-erythrose and.
