Why do you suppose the monosaccharide glucose is circulated in the blood of humans rather than a disaccharide such as sucrose which is the transport sugar found in plants?

Glucose is circulated in the blood of humans because it is a monosaccharide that can be rapidly and easily utilized by cells for energy. Its simple structure allows for quick absorption and immediate use, which is essential for maintaining blood sugar levels and providing energy to tissues. In contrast, sucrose, a disaccharide, must be broken down into monosaccharides before it can be utilized by cells, making it less efficient for rapid energy needs in humans. Additionally, glucose plays a critical role in regulating metabolism and hormonal responses in the human body.
