Study Notes
Glucose
- Glucose is a type of simple sugar, also known as dextrose, with a molecular formula of C6H12O6.
- It is found in fruits and honey, and is the source of energy in cell function.
- Glucose is the main source of energy for the body, and is converted from carbohydrates.
Glucose Molecules
- Molecules of starch, a major energy-reserve carbohydrate in plants, consist of thousands of linear glucose units.
- Cellulose, another major compound composed of glucose, is also linear.
Blood Glucose Regulation
- Blood glucose regulation involves maintaining blood glucose levels at a constant range of 60-100 mg/dL in adults.
- Two main hormones, insulin and glucagon, control blood glucose levels.
- Insulin is released when there are high amounts of glucose in the blood stream, while glucagon is released when there are low levels of glucose.
- The brain requires a constant flow of glucose, using about 120 grams daily or 60% of total glucose used by the body at rest.
Blood Glucose Test
- A blood glucose test, also known as a Blood Sugar Fasting test, measures the amount of glucose in the blood.
- Proper blood glucose regulation is crucial to maintain the health of the human body, as the brain and other organs could starve without it, leading to death.
