Document Summary
Fat burns in the fires of carbohydrate. When little cho coming from the diet and glycogen stores are low the liver uses amino acids to make glucose. Sufficient dietary cho spares the breakdown of body proteins. Rda for cho is 130 g/day for adults. Prevent ketosis and minimize amino acid use for glucose synthesis. Important for those on a low-calorie diet to consume this amount. Low cho diets promote ketosis, but it is important to get enough protein in the diet. Protein transporter is required for uptake for all cells. The amount of functional transporters on cell membranes is controlled in some cells- but not all-by insulin. Cells relying on blood concentration regulation can be damaged by poor control. Neurons with poor control can lead to neuropathy. Takes up glucose from the blood when concentration is high. Delivers glucose to the bloodstream when concentration is low. Take up lots of glucose in response to insulin.
