Document Summary
Oligosaccharides - a carbohydrate whose molecules are composed of a relatively small number of monosaccharide units. Polysaccharides - plant starch and animal glycogen. Carbohydrates are our main source of energy. Energy in carbohydrates originally came from the sun via photosynthesis: simple sugars. A hexose sugar found especially in honey and fruit. A syrup containing glucose and other sugars, made by hydrolysis of starch. Even though they are both a combination of glucose and fructose. In terms of chemical structure, the fructose and glucose in high fructose corn syrup are not bound together like in granulated sugar (sucrose). : oligosaccharides = 3-10 monosaccharide units linked together in a chain. We do not have the enzymes to digest their beta-glycosidic bonds (harder to digest) They are fermented by the bacteria in the colon. These gut bacteria produce short-chain fatty acids and some b-vitamins (providing a benefit to us). Helps shape a healthy intestinal microbe population in infant: polysaccharides =
