The carboxylation of acetyl CoA to synthesize malonyl CoA by acetyl CoA carboxylase requires assistance from Vitamin K Vitamin D Vitamin B5 Vitamin 87
In type I diabetes mellitus, excessive production of acetyl-CoA may surpass the body’s capacity to oxidize it. As a result, acetoacetate, β-hydroxybutyrate, and acetone (ketone bodies) accumulate. When generated in large amounts, blood pH falls, thereby reducing the capacity of red blood cells to carry oxygen. Explain in general terms how high concentrations of ketone bodies may result in a fatal coma.
