Document Summary

Midterm is 2 hours long; no lecture on february 23rd. Lab on tuesday and lab quiz in tutorial on thursday. Midterm will be on biological macromolecules to metabolism and enzymes. Final will be on information from cellular respiration onwards. Covalent bonds are very strong compared to other bonds which is why macromolecules are composed of them. He asks many questions on the exam involving the differences between two related concepts. Enzymes take the linear structures in monosaccharides and transform them into ring structures: glucose and glucose (maltose) undergoes dehydration and is joined by the glycosidic linkage. Amylose is a linear structure unlike amylopectin. Difference between alpha glucose and beta glucose monomer: positioning of hydroxyl group (alpha glucose is the down position and beta glucose is in the up position) For cellulose the alternating positioning of the hydroxyl group is because it puts less strain on the molecule.
