Document Summary
Amino acid, nucleotide, monosaccharide = monomer polypeptide, nucleic acid, polysaccharide = polymer. Fischer projection - horizontal out of plane, vertical into plane epimers: sugars that differ at a single asymmetric c. D-glucose nomenclature (length): triose (c3) tetrose (c4), pentose (c5), hexose (c6) numbered from aldehyde or ketone reaction of aldehyde or ketone with a hydroxyl on another c can cyclize tetrose and larger. Chen3701_biomolecularengineering page 2 ring can be in chair form or boat form boat form is less common than chair form. Amino sugars - hydroxyl replaced amino (often acetylated) glucose-6-phosphate beta-acetylglucosamine. Reduction disaccharide - two monosaccharides linked by a glycosidic bond there isn"t additional ch2 group, but just to show direction that bonds go (galactose) (glucose) lactose molecule above polysaccharides. Starch: fuel storage in plants, glucose polymer (amylose (unbranched), amylopectin (branched)) Glycogen: fuel storage in animals; extensively branched glucose polymer.
