Each sample is stained with an in-house generated HPA-antibody and counterstained with markers for microtubules, the endoplasmic reticulum and the nucleus. You will further uncover a bit about the function of coenzyme A . Thus, in vitamin B 12 deprivation propionyl-CoA competes with acetyl-CoA as substrate providing a mechanism for odd chain fatty acid production, and its product, methylmalonyl-CoA, may function as an inhibitor of the enzymes of fatty acid synthesis .
