Consider the structures of arabinose and ri-bose. Explain why nucleotide derivatives of arabinose, such as ara-C and ara-A, are effective metabolic poisons.
Answer to relevant QuestionsConvert the following Haworth projections to a Fischer projection. Name the monosaccharides you have drawn. Draw Haworth projection formulas for dimers of glucose with the following types of glycosidic linkages: (a) A β(1 → 4) linkage (both molecules of glucose in the β form) (b) An a,a(1 → 1) linkage (c) A β(1 → 6) ...Based on what you know about glycosidic bonds, propose a scheme for formation of covalent bonds between the carbohydrate and protein portions of glycoproteins. The M and H subunits of lactate dehydrogenase have very similar sizes and shapes but differ in amino acid composition. If the only difference between the two were that the H subunit had a glutamic acid in a position where ...Show, by a series of equations, the energetics of phosphorylation of ADP by phosphoenolpyruvate.
