B TU. XX AD.A. E O T Normal No Spac. Heading 1 Heading 2 Title Font Paragraph Styles 18. The following amino acids are related in one way: five are related in another way, glu (E) his (H) leu (L.) gin(Q) pro (P) arg (R) Which of the following answer choices has the correct way they are all related (A): way one is different (B), and; the amino acid that is different (C! Answer All of them have (A) Only five of them (B) The odd one is (C) a) A five-carbon chain are linked via amide bonds in protein synthesis. b) A five-carbon chain may be made into a-ketoglutarate and are thus glucogenic. More than five carbons total are essential A five-carbon chain have a side chain that is branched or attached to the a-amino group. More than five carbons total have more than one amino and carboxyl group 19. Which of the following trivialities is NOT correct? a) L and K are the only amino acids that are strictly ketogenic because they cannot be made into glucose b) A, C, G, and T are the only amino acids that may be 100% glucogenic, i.e, all of their carbons may be made into glucose. c) All glucogenic amino acids require gluconeogenesis reactions and thus energy to be made into glucose. D and N are the most directly (and cheapest) to make into glucose. d) F, Y. 1, and Ware all: 1) aromatic/aliphatic; 2) partially glucogenic because some of the carbon skeleton may be made into pyruvate or some citric acid cycle intermediate; and 3) partially strictly ketogenic" as some of the carbon skeleton may only be metabolized to acetoacetyl-CoA/acetyl-CoA. e) E, H, Q. P, and R are considered glucogenic because 60% of their total carbons may be made into a-ketoglutarate and thus into glucose. 20. The choice above that is NOT correct, is not correct because: a) other amino acids are also completely strictly ketogenic. b) other amino acids also may be 100% glucogenic, Le all of their carbons may be made into glucose c) D and N have to go through many more reactions than other amino acids to be made into oxaloacetate to be gluconeogenic d) they are not all either aromatic or aliphatic amino acids. e) more of their total carbons may be made into a-ketoglutarate but only 60% of these carbons may be glucogenic

Answer 1

18 the answer will be option D as the proline dont have any side chain. and all of them atleat contain a fice carbon chain.
