BIOL 4087 : 4087 Exam 2 Notes Part 1
Document Summary
Fuel, carbon skeletons for synthesis, a part of rna and dna, cell-cell interactions in glycoproteins and glycolipids. Figure 7-1a left: has aldose (glyceraldehyde); right has ketose (dihydroxyacetone) Figure7-5 hemiacetal and hemiketal stable form in solution. Oh attacks: more beta conformations than alpha. Fig 7-6 glucose forms rings in solution (glucopyranose) cyclize to make hemiacetal: alpha configuration ~36% in solution and the beta is ~64% In configuration, oh is on opposite side of ring as ch2oh. In configuration, og is on the same side of ring as ch2oh. Figure 7-7: anomeric carbon can be in the hemiacetal or hemiketal. Figure 7-8: 6-membered ring favors chair configuration. Oh is more stable in the equatorial position than the axial position, that"s why the beta configuration is more stable. Figure 7-9 examples of modified carbohydrates" (hexose derivatives) don"t have to recognize. Just know names and abbreviations (abbreviations found in table 1 and below).
