41. An acetyl group is then added by LPC acetyltransferase ( LPCAT ) to produce PAF. 42. The aroma is caused by the evaporation of 2-Acetyl -1-pyrroline. 43. Where the acetyl group displaces the hydrogen atom in the central hydroxyl group of carnitine. 44. Many organisms have the capacity to produce butanol utilizing an acetyl -CoA dependent pathway. 45. TunH then catalyzes the hydrolysis of UDP from UDP-N-acetyl -tunicamine. 46. Thus, the two products are pyruvate dehydrogenase ( acetyl -transferring ) and phosphate. 47. ACO stands for acetyl -CoA, which is shown in its bent J configuration. 48. But there is loss to remove acetyl . 49. Homocitrate is initially synthesised from acetyl -CoA and 2-oxoglutarate by homocitrate synthase. 50. It consists of ferrocene substituted by an acetyl group on one of the cyclopentadienyl rings.
