What is the polyol pathway? | once inside of the cell, glucose that is not immediately needed for ATP production is moved down this metabolic pathway where glucose is converted to sorbitol and eventually fructose |
What causes over-activation of the polyol pathway? | hyperglycemia, which allows too much glucose into the cell |
What happens to the body of an overactive polyol pathway? | the accumulation of sorbitol increases the osmotic pressure of the cytoplasm which draws water into these cells; the consequence is cellular swelling, which leads to cell dysfunction/injury; it increases the susceptibility of the cell to oxidative stress |
