Scientists have discovered a new form of ‘ultra-bad’ cholesterol that increases the risk of heart disease. It was found to be present in the elderly and type 2 diabetes sufferers. Metformin might help.
Seriously?!? LDL and HDL are not even cholesterol but "Lipoproteins" which transport cholesterol around the body. And they do not "stick to the artery walls" but rather the plaques are found INSIDE the layers of the artery walls.The fatty material is stickier than the common form of ‘bad’ cholesterol, making it more likely to attach to artery walls.
In organisms, methylglyoxal is formed as a side-product of several metabolic pathways. It may form from 3-amino acetone, which is an intermediate of threonine catabolism, as well as through lipid peroxidation. However, the most important source is glycolysis.
