What are the primary components of fats?
Fats are primarily composed of carbon, hydrogen, and oxygen atoms.
What is the most common form of fat in the diet?
Triglycerides, consisting of three fatty acid molecules bound to a glycerol molecule.
How do saturated and unsaturated fats differ in terms of physical state at room temperature?
Saturated fats tend to be solid at room temperature, while unsaturated fats are usually liquid.
What role do phospholipids play in the body?
Phospholipids are crucial for maintaining cellular structure and function, as they are a major component of cell membranes.
How much energy does 1 gram of fat provide?
1 gram of fat provides 9 kcal of energy.
What is the function of bile in fat digestion?
Bile emulsifies fats in the small intestine, breaking large fat globules into smaller droplets to increase surface area for enzyme action.
