Additionally, RBP improves retinol function[11] and plays a crucial part in carbohydrate and lipid metabolism, metabolic syndrome, insulin resistance, vascular endothelial injury, atherosclerosis, and CHD.[12] Myocardial ischemia-modified albumin (IMA) is a biochemical index that reflects ischemia and hypoxia of cells in the body. This evidence concerns the gene ALB and coronary artery disorder.
