31. The ionized carboxyl groups coordinate as ligands to the chromium ( III ) centers of the oxo-hydroxide clusters. 32. In low-ester pectins, ionic bridges are formed between calcium ions and the ionised carboxyl groups of the galacturonic acid. 33. Carnitine binds to CRAT in a partially folded state, with its hydroxyl group and carboxyl group facing opposite directions. 34. A participating group, typically one with a carboxyl group present, will predominantly result in the formation of a ?-glycoside. 35. The amino acid is joined by its carboxyl group to the 3'OH of the tRNA by an ester bond. 36. Consequently, the methylene group ?-to the carboxyl group in the product is the methylene group from the diazomethane reagant. 37. The carboxyl group of Asp296, also coplanar with the substrate purine ring, forms hydrogen bond with N7 of the substrate. 38. With a hydroxyl group adjacent to the carboxyl group , lactic acid is classified as an alpha-hydroxy acid ( AHA ). 39. In the interaction of candesartan with AT 1 receptor the carboxyl group of the benzimidazole ring plays an important role. 40. To convert m-xylene on an industrial scale to isophthalic acid, the two methyl groups are both oxidized to carboxyl groups .
