Which type of fat is primarily stored as reserves in the body?

• A. Phospholipids
• B. Saturated fats
• C. Triglycerides
• D. Trans fats

Answer: (C)

Triglycerides are the primary form of fat that the body stores as reserves. They consist of three fatty acid molecules attached to a glycerol backbone. This structure makes triglycerides an efficient way for the body to store energy because they can be packed densely and are a concentrated source of calories. When the body requires energy, particularly during times of fasting or extended physical activity, triglycerides can be broken down into fatty acids and glycerol to provide fuel. In contrast, phospholipids are predominantly used in cell membrane structure rather than energy storage. Saturated fats and trans fats are types of fatty acids but are not the primary storage form of fat in the body. While they can be present in stored fat, they do not represent the main component of fat reserves. Therefore, triglycerides are the preferred form for energy storage due to their composition and the body's metabolic processes.
