Document Summary
Lecture notes/narrated video slides: carbohydrates, or sugars, are one of the 4 main classes of compounds in living cells. If this group is at the end of the molecule aldose (has aldehyde group) Convert a cyclized monosaccharide b/w fischer and haworth projections. Instead, they"re found in chair or boat conformations: the chair conformation is more energetically favourable. Describe how monosaccharides are joined to make polysaccharides: 2 monosaccharides can join together in a condensation reaction (atoms of water are removed) to make a disaccharide, e. g. lactose. Biochem section 2, topic 7 notes carbohydrate structure. Compare the structures of polysaccharides used for energy storage. Describe the difference b/w dietary fibre and carbohydrates used for energy metabolism. Important energy currency and for dna and rna: linked to lipids or proteins on the surface of cells to protect the cells, make them slippery, and for recognition purposes.
