Metabolism of carbohydrates

Carbohydrate metabolism is how your body processes sugars and starches from food. When you eat carbs, your digestive system breaks them down into simple sugars like glucose, which enters your bloodstream. Your body then uses insulin to help cells absorb glucose for energy. Excess glucose can be stored in the liver and muscles as glycogen or converted into fat for long-term storage. During periods of fasting or energy demand, stored glycogen is broken down back into glucose to provide fuel. Overall, carbohydrate metabolism balances energy production and storage, ensuring your body has the necessary fuel to function efficiently.
