Problem set 1: All problems are assigned from the 6 th edition of biochemistry by Stryer et al. Chapter 11: Carbohydrates: Page 324-325 1, 4, 7, 9, 12. For #4, prove it – remember your math for solving two variables. For #7, see page 309 and don’t forget your organic chemistry!!! Chapter 15: Metabolism and Thermodynamics Pg 431-432 1, 3, 5, 7, 8, 9, 12, 13. For 3a, just calculate G o’ . For #5, G o’ hydrolysis of ATP to AMP is –45.6 kJ/mole. G o’ hydrolysis of Acetyl CoA to acetate and CoASH (CoA) is –31.4 kJ/mole. For #12, G o’ hydrolysis of ATP to ADP is –30.5 kJ/mole. Also, try this: You’re a biochemist hired by NASA to study the results of a probe sent to Rhea, an earth sized planet several light years away. There is a large amount of excitement over Rhea as it contains several primitive life forms resembling plants that contain

Unformatted text preview: carbohydrates and proteins! It is currently hypothesized that these “plants” could provide a source of nutrients for any future manned missions to Rhea. The most recent “plant” data from the probe is listed below: Carbohydrates: Two disaccharides detected: α-L-glucopyranose linked to β-L-fructofuranose in an α1-β2 arrangement. β-L-galactopyranose linked to α-L-glucopyranose in an α1-4 arrangement. Protein amino acid composition: D-glycine 7.5% D-alanine 7.2% D-serine 5.7% … More data in next transmission. Armed with this, you dash into your supervisors’ office!!! What have you learned from this latest dataset from the probe? Why is it important?...
