A triglyceride is made up of a three-carbon molecule called glycerol, and of three fatty acid tails attached to the glycerol. Method for producing fatty alcohols includes splitting vegetable oils and animal fats under pressure into fatty acids and glycerol in counterflow to steam. Explain how the fatty acid composition of the triglycerides determines whether a substance is a fat or oil. Vitamins A, C, D3, and zinc are the top-rated formula.
