Notes:   - This post is a joke, admittedly a weird one, which is why it is labeled “humor” and is filed under “Abstract humor”.   - I apologize for this spoiler. Some people probably like humor posts better if they do not know what they are in advance, but several others may think that reading a post like this is a waste of their time. If you are in the latter category, move on to another post! If not, here it goes … *** Today I was spending some time under the sun, in one of the year’s 364 sunny days in Laredo, Texas. The goal was to see if I could obtain a precise count of the number of advanced glycation endproducts (a.k.a. AGEs) that would form as my skin was exposed to the sun’s damaging rays. Then I read a post by Peter at Hyperlipid, and inspiration consumed me. A new theory was born regarding the interplay of LDL, chylomicrons, HDL, and atherosclerosis. By the way, Peter is a fat genius, by which I mean a genius regarding all fat issues – who happens to be t...

High-density lipoprotein (HDL) is one of the five main types of lipoproteins found in circulation, together with very low-density lipoprotein (VLDL), intermediate-density lipoprotein (IDL), low-density lipoprotein (LDL), and chylomicrons. After a fatty meal, the blood is filled with chylomicrons, which carry triglycerides (TGAs). The TGAs are transferred to cells from chylomicrons via the activity of enzymes, in the form of free fatty acids (FFAs), which are used by those cells as sources of energy. After delivering FFAs to the cells, the chylomicrons progressively lose their TGA content and “shrink”, eventually being absorbed and recycled by the liver. The liver exports part of the TGAs that it gets from chylomicrons back to cells for use as energy as well, now in the form of VLDL. As VLDL particles deliver TGAs to the cells they shrink in size, similarly to chylomicrons. As they shrink, VLDL particles first become IDL and then LDL particles.
