What are carbohydrates primarily composed of?

Carbohydrates are primarily composed of carbon, hydrogen, and oxygen atoms. This composition gives carbohydrates their unique properties and plays a crucial role in their function within the body. The ratio of hydrogen to oxygen in carbohydrates typically mirrors that of water (2:1), which is important in cellular processes and energy production.

The distinctive structure of carbohydrates—ranging from simple sugars to complex molecules—derives from the arrangement of these atoms, allowing for various functions in energy storage and distribution. As the body breaks down carbohydrates, it converts them into glucose, which is a primary energy source for cells.

Understanding the composition of carbohydrates is fundamental in nutrition, as it helps in recognizing how they contribute to dietary needs and how varying types of carbohydrates can impact health. The other options include components that do not accurately represent the primary building blocks of carbohydrates, thus making them unsuitable choices.
