Carbohydrates are primarily found in the body in the form of glucose, glycogen, and as part of various biomolecules. Glucose is the simplest form of carbohydrate and is absorbed directly into the bloodstream after consuming carbohydrate-rich foods.
Once in the bloodstream, glucose can be utilized by cells for energy or stored for later use. The body stores excess glucose as glycogen, primarily in the liver and muscles. Glycogen serves as a readily available energy reserve, which can be broken down into glucose when needed, such as during physical activity or between meals.
In addition to glucose and glycogen, carbohydrates also play crucial roles in various biological molecules. For example, they are components of DNA and RNA and are involved in cell signaling. Overall, carbohydrates are vital for energy production and numerous physiological functions within the body.
