Document Summary
Burst of protein synthesis in the liver after a protein-rich meal. Mostly in muscles, but also in most tissues. Stored mostly in adipose, but also in other tissue and blood as triglycerides. Does not produce atp as fast as carbohydrates. Maintains blood glucose which is stored as glycogen in muscle and liver. Glucose can be used as energy in anaerobic or aerobic respiration. Not very much is stored in the body. Main function of our gastrointestinal tract digests and absorbs nutrients from foods. Small intestine is the main site of fat absorption, sugar, amino acids, vitamins and mineral absorptions. Intestinal cells package some lipids and lipid soluble vitamins into chylomicrons. These are processed by lymphatic system which eventually delivers them to the blood as dietary. Very regulated, especially compared to free fatty acids which range widely. Many cells and tissues use glucose and cannot really use free fatty acids as a fuel source.
