DIET 4475 Lecture Notes - Lecture 9: Ketosis, Glycogen, Blood Sugar
Document Summary
Lecture 9: functions of carbohydrates and glucose regulation. Glucose for energy: primary function of carbohydrates is to provide energy for cells, red blood cells, the brain, and nerve tissue primarily rely on glucose for energy, spares protein and prevent ketosis, using glucose to make other compounds. ~100g of the body"s glycogen reserve is in the liver, remainder is in muscle 300- 400g (more in some athletes: protein sparing: nonessential amino acids. In a 70-kg healthy man, the liver contains approximately 100 g of glycogen, which has the potential to provide~400 kcal of energy. Insulin: -released from pancreas beta cells so that glucose can be taken into cells to lower glucose concentrations back to fasting levels, glycogenic, antigluconeogenic, antilipolytic, and antiketotic in its actions. It favors storage of absorbed nutrients and is, therefore, an anabolic hormone: insulin stimulated the liver and muscles to store excess glucose as glycogen.
