BIOL 1107 Lecture Notes - Lecture 5: Linear Form, Oligosaccharide, Glycogen
Document Summary
Chapter 5 lecture notes: carbohydrates, monosaccharides and polysaccharides. Pentose (five: hexose (six, aldose vs ketose. Aldose = carbonyl group at end of carbon chain. Ketose = carbonyl group in middle of chain: spatial arrangement of their atoms, different arrangement of hydroxyl groups, linear and alternative ring forms. Potential that there is a difference in polarity and the cell picks up on the difference. Bring in an enzyme, enzymes are specific to each structure, so it can easily differentiate between the different structures: linear form of glucose, added to an aqueous solution forms a ring structure. Alpha - bond formation is like a v. Beta-bound formation is like an upside down v (glucose is flipped: plants store sugar as starch, animals store sugar as glycogen, starch - not as many branches, can form much more rigid structure without as many helices.
