11. In biochemistry, the acetyl group , derived from acetic acid, is fundamental to all forms of life. 12. The hydroxyl groups in locations C2 and C3 in mannose are partially substituted by acetyl groups . 13. Histone Deacetylases ( HDACs ) are a class of enzymes that remove acetyl groups from histones. 14. Pyruvate is made from glucose during the glycolysis and transformed to an acetyl group during transition reaction. 15. There is one picture included in the article, but is only a picture of an acetyl group . 16. However, removal of the acetyl group by histone deacetylases ( HDACs ) condenses DNA structure, thereby preventing transcription. 17. The acetyl group is used in the Krebs cycle and the phase ends with the electron transport chain. 18. CoA is acetylated during breakdown of carbohydrates through glycolysis, as well as by the GTP per acetyl group . 19. In the next two steps, the benzyl protecting group in compound "'41 "'was replaced by an acetyl group . 20. Both of these products resulted from the loss of the acetyl group from the inferred ethyl 2-aminoacetoacetate intermediate.
