Glukosequellen

Glukosequellen refers to the sources from which glucose, a simple sugar and a primary source of energy for living organisms, is obtained. In the human body, glucose is mainly derived from the digestion of carbohydrates consumed in the diet. These carbohydrates can be simple sugars like those found in fruits and honey, or complex carbohydrates such as starches present in grains, potatoes, and legumes.

When these carbohydrate-rich foods are eaten, digestive enzymes break them down into glucose, which is then absorbed into the bloodstream. This process leads to an increase in blood glucose levels, signaling the pancreas to release insulin. Insulin helps transport glucose from the blood into cells for energy production or storage as glycogen in the liver and muscles.

Besides dietary intake, the human body can also synthesize glucose through a process called gluconeogenesis. This occurs primarily in the liver and kidneys, especially during periods of fasting or low carbohydrate availability. Gluconeogenesis uses non-carbohydrate precursors, such as amino acids, lactate, and glycerol, to create glucose, ensuring a stable supply for vital organs like the brain, which relies heavily on glucose for its function. Photosynthesis in plants is the ultimate natural source of glucose, as plants use sunlight, water, and carbon dioxide to produce glucose, forming the base of many food chains.
