HUMAN NUTRITION

Detailed explanation-1: -Triglycerides, cholesterol and other essential fatty acids-the scientific term for fats the body can’t make on its own-store energy, insulate us and protect our vital organs. They act as messengers, helping proteins do their jobs.

Detailed explanation-2: -Fat is used for energy during exercise, especially after glycogen is depleted. Fats are packed together tightly without water and store far greater amounts of energy in a reduced space. A fat gram is densely concentrated with energy-it contains more than double the amount of energy than a gram of carbohydrate.
