Document Summary
Carbs are c-based molecules that are rich in hydroxyl groups (-oh) Empirical formula for many carbs is (ch2o)n carbon hydrate. Polysaccharides polymers of covalently linked monosaccharides; complex carbs. Can be very simple or very complex. Variety of monosaccharides and the multiplicity of linkages mean that carbs provide cells w/ a vast array of 3d structures that can be used for a variety of purposes energy storage, cell recognition signals, etc. Carbonyl group: c double bonded to o. Ketone: c double bonded to o, anywhere in molecule. Aldehyde: c double bonded to o, at one end of the molecule. Monosaccharieds serve as fuel molecules, but are also fundamental constituents of living systems. Dna"s backbone consists of deoxyribose cyclic 5-c sugar. Monosaccharides are aldehydes or ketones that have 2 or more hydroxyl groups. Smallest monosaccharides are composed of 3 c atoms, and are thus called trioses: D-glyceraldehyde (aldose) oh on the right. L-glyceraldehyde (aldose) oh on the left.
