What do carbohydrates change into inside the body?

Carbohydrates are primarily converted into glucose in the body through the process of digestion. Once glucose enters the bloodstream, it can be used immediately for energy or stored in the liver and muscles as glycogen for later use. If there is an excess of glucose, it can be converted into fat for long-term energy storage. Overall, carbohydrates serve as a crucial source of energy for the body's functions.
