Document Summary
Is a hydrate of carbon : manufactured by plants. 6co2 + 6h20 + energy > c6h22o6 + 6o2. Types of dietary carbohydrates: sugars, starch, fibre. Difference comes from how they are linked together; body reacts differently to what we eat. C6h12o6 > different structure but all simples have same formula. Monosaccharides: simplest form of cho: contains 3 to 9 carbon atoms looking for ones that contain 6: glucose*** (fuel), fructose, galactose. Disaccharides: sucrose (g&f) , lactose (g&g), maltose (2 glucose) ==> easily broken (infinity sign) - easily broken b/c clean fit into enzyme for fibre it is b-glycosidic bond and the bond goes into the page; enzyme there does not have spot for. Plants: starch (amylopectin - most of storage form of glucose in plants and amylose; So, why do we need to eat carbohydrates: energy needs -give them!!!, fuel source for neurons (only uses glucose except during starvation . can uptake protein. Usually by 2nd semester and then usually disappear.
