Triacylglycerols made up of large saturated fatty acids have high melting points and are solid in room temperature, vice versa 23.2A HYDROGENATION OF TRIACYLGLYCEROLS Solid commercial cooking fats are manufactured by partial hydrogenation of vegetable oils. Completed hydrogenation of the oil is very hard and brittle One commercial advantage of partial hydrogenation is to give the fat a longer shelf-life 23.2B BIOLOGICAL FUNCTION OF TRIACYLGLYCEROLS The primary function of triacylglycerols in animal is as an energy reserveTriacylglycerols made up of large saturated fatty acids have high melting points and are solid in room temperature, vice versa. 23.2A HYDROGENATION OF TRIACYLGLYCEROLS Solid commercial cooking fats are manufactured by partial hydrogenation of vegetable oils.
