Which of the structures below represents a fat?

The right answer is A glycerol molecule with three fatty acid chains attached to it.

This structure is called triglycerides (glycerol + 3 fatty acids).

Triglycerides are part of the cholesterol of lipid compounds or fats of the body. They are the main energy reserve of the body and are therefore beneficial for staying in shape, provided that the blood levels are in the normal range. When triglyceride levels are high, cardiovascular risk increases.

Prokaryotic cells have entirely different structures for organizing their DNA, the prokaryotic chromosome equivalent is called a genophore and is localized within the nucleoid region... The structure of chromatin networks is currently poorly understood and remains an active area of research in molecular biology.
