Document Summary

Carbohydrates account for 40-80% of an individual"s energy intake. Primary role: provide energy to all the cells in the body. Brain cells require energy in the form of glucose. Average minimum amount of glucose used by the brain determines the human requirement for carbohydrates. Rda is 130 g/day (increases for pregnancy and lactation), both men and women. Carbohydrates are a string of beads, and the individual bead is a monomer (a sugar unit) Examples are sucrose (table sugar- glucose + fructose), lactose (milk sugar- glucose+ galactose) and maltose (glucose+ glucose). Oligosaccharides 3 to 10 sugar units and may be produced by the breakdown of polysaccharides. Raffinose is trisaccharide of galactose-glucose-fructose, while stachyose is a tetrasaccharide of galactose-galactose- glucose-fructose. The different kind of linkages between the sugar units in these oligosaccharides make them undigestible by enzymes in any animal system. Some of the gut bacteria can digest them partially and they in turn produce gas.
