A glükózzá, or glucose, is a simple sugar that serves as a primary source of energy for the body's cells. It is a monosaccharide, meaning it consists of a single sugar molecule. Glucose is found in various foods, especially in carbohydrates like fruits, vegetables, and grains. When consumed, the body breaks down these carbohydrates into glucose, which is then used for energy or stored for later use. In the bloodstream, glucose levels are regulated by hormones such as insulin and glucagon. Insulin helps cells absorb glucose, lowering blood sugar levels, while glucagon raises blood sugar levels when needed. Maintaining balanced glucose levels is crucial for overall health, as imbalances can lead to conditions like diabetes.
