The coenzyme was first isolated from large quantities of pig liver extract as the factor required for the acetylation of sulfanilamide, the assay system used to track CoA during its purification. Coenzyme A (CoA) was discovered by Fritz Lipmann and his colleagues in the early 1950s. However, the effect of acetyl-CoA levels on histone acetylation status in plants remains unknown. Thus, although Lipmann was able to show that energy transfer between respiration and acetylation occurred by way of phosphate bonds, he was unable to prove the involvement of acetyl phosphate.
