41. Compared to Metol, glycin has a carboxyl group attached to the methyl group of the Metol. 42. When ATP is not present, the negative charge of the E501 carboxyl group balances this charge. 43. Instead, it has a carboxyl terminal end that shows no sequence homologies to any other proteins. 44. Amine-modified oligonucleotide probes attached to carboxyl groups on quantum dots show sequence-specific hybridization. 45. Elongation of the polypeptide chain involves addition of amino acids to the carboxyl end of the growing chain. 46. The hCPT s hydroxyl has less inductive effect on the carboxyl group which makes the lactone very reactive. 47. Acylphosphatase is a small cytosolic enzyme that catalyzes the hydrolysis of the carboxyl -phosphate bond of acylphosphates. 48. "' Thiosalicylic acid "'is an organosulfur compound containing carboxyl and sulfhydryl functional groups. 49. The peptides are 81 % identical, with the carboxyl terminal sequence 14 amino acids longer in rattin. 50. Its surface is covered with epoxy, hydroxyl, and carboxyl groups that interact with cations and anions.
