Document Summary

Car(cid:271)ohydrates are the (cid:373)ai(cid:374) fuel sour(cid:272)e for so(cid:373)e of the (cid:271)ody"s (cid:272)ells: brain cells, nerve cells, red blood cells- exclusively use (cid:272)ar(cid:271)ohydrates (cid:271)e(cid:272)ause they do(cid:374)"t ha(cid:448)e (cid:373)ito(cid:272)ho(cid:374)dria, so they (cid:272)a(cid:374)"t use protei(cid:374)s or lipids, exercising muscle. Sources of carbohydrates in the body: blood glu(cid:272)ose (cid:374)eeds a (cid:272)ertai(cid:374) a(cid:373)ou(cid:374)t to (cid:862)feed(cid:863) the (cid:271)rai(cid:374) Glucose= sugar in the body: liver glycogen is stored glucose, but it can only be stored for 18 hours. About 50% or more of our calories come from carbohydrates. 6co2 + 6h2o + energy c6h12o6 (glucose) + 6o2: metabolism. C6h12o6 (glucose) + 6o2 energy + co2 + h2o. Complex carbohydrates (polysaccharides) are starches and fibers. Simple carbohydrates: monosaccharides- (cid:862)(cid:373)o(cid:374)o(cid:863) (cid:373)ea(cid:374)s o(cid:374)e, these are the (cid:271)asi(cid:272) u(cid:374)its of all carbohydrate structures. Glucose, fructose, galactose (6 carbon sugars: disaccharides- (cid:862)di(cid:863) means two. Formed by the chemical bonding of two monosaccharides. These (cid:272)a(cid:374)"t (cid:271)e a(cid:271)sor(cid:271)ed; they ha(cid:448)e to (cid:271)e digested first. Sucrose (table sugar) = glucose and fructose.
