fatty acids and 1 glycerol (triglycerides) 25-35% of total calorie intake
Saturated fat - Answer Solid at room temperature. Bonded to as many hydrogen atoms
as possible. Comes from animal products (meat, milk)
Unsaturated fat - Answer Liquid at room temperature. More common in plants. Carbon
atoms do not hold the maximum number of hydrogen atoms
Monounsaturated fat - Answer Contain fatty acids that only have one set of double-
