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.
Detailed explanation-3: -Long-term energy.As mentioned prior, fats function as the body’s primary long-term energy storage molecule. They are an efficient way to store energy due to their compact molecular structure.
Detailed explanation-4: -Triglycerides are the primary form of long-term energy storage in plants and animals. Fatty acids are long chains of 12 to 24 hydrocarbons with a carboxyl group at the end. Bonding within fatty acid chains gives fats and oils their characteristics.
Detailed explanation-5: -Adipose (fat) cells are specialized for the storage of energy in the form of triglycerides, but research in the last few decades has shown that fat cells also play a critical role in sensing and responding to changes in systemic energy balance.
