<prompt> First fatty acid to form in fatty acid synthesis:Palmitic acidStearic acidOleic acidPantothenic acid  <response>: Ans. A Palmitic acid Palmitic acid is the most common fatty acid found in animals, plant and microbes. Excess carbohydrates and proteins are converted to palmitic acid. Palmitic acid is the first fatty acid synthesized during fatty acid synthesis. Note: First step in fatty acid synthesis is transfer of acetate units from mitochondrial acetyl CoA to the cytosol.
