The two amino acids, glycine and alanine, can form two different dipeptides. Draw one of the possible dipeptides as it would appear at a pH of 7. Be sure to include any necessary nonzero formal charges in your drawing!

Both 1,2−dihydronaphthalene and 1,4−dihydronaphthalene may be selectively hydrogenated to 1,2,3,4−tetrahydronaphthalene. one of these isomers has a heat of hydrogenation of 101 kj/mol (24.1 kcal/mol), and the heat of hydrogenation of the other is 113 kj/mol (27.1 kcal/mol). match the heat of hydrogenation with the appropriate dihydronaphthalene.
