Which statement correctly describes triglycerides?

Which statement correctly describes triglycerides?

• A. They are the primary protein in blood plasma.
• B. They are a storage form of carbohydrate.
• C. They are a type of cholesterol that clears arteries.
• D. They are the primary form of fat in the blood, derived from diet and liver synthesis, stored as energy in adipose tissue.

Answer: (D)

Triglycerides describe how the body stores and uses fat. They’re a type of lipid made of glycerol with three fatty acids and are carried in the blood within lipoproteins, coming from both the fats we eat and liver synthesis. They’re stored in adipose tissue as energy reserves that can be mobilized when needed. This makes the statement correct because it captures their role as the primary fat in circulation and in storage, plus their dietary and hepatic origins. They are not proteins (A), not a carbohydrate storage form (B), and not cholesterol (C).
