Why carbohydrates are stored as glycogen?

Carbohydrates are stored as glycogen because glycogen serves as a readily accessible source of energy for the body. It is a highly branched polymer of glucose, allowing for rapid mobilization of glucose when energy is needed, such as during exercise or fasting. Storing carbohydrates as glycogen also helps to maintain blood sugar levels, ensuring a consistent energy supply for vital organs. Additionally, glycogen storage minimizes osmotic pressure compared to storing glucose directly, making it more efficient for the body.
