Chylo..wha? HDL, LDL and what are.

Science lesson time! Here's how you absorb lipids - and the end products.

Larger fat molecules are mixed with bile and become micelles. This allows fats to be moved to the intestinal cells. In intestinal cells, cholesterol and lipids are packed with protein. These are chylomicrons. Chylomicrons are released into the lymphatic system. They enter the bloodstream near the heart and then blood carries these lipids to the rest of your body for immediate use or storage.

As you know, fats and water don't mix. Because proteins are surrounding the structure, these chylomicrons allow fats to be transported through the watery blood.

As the chylomicron goes through the body cells snatch up triglycerides from the chylomicrons and as it floats around it gets smaller and smaller. Eventually it gets back to your liver.

Here lipids your liver has been assembling and ones collected from the smaller chilomicron are packaged with more proteins as VLDL or very low density lipoproteins. This configuration is then shipped through the body again and cells again remove triglycerides, causing it to shrink. As triglycerides are taken up, the VLDL becomes mostly cholesterol. Now this is LDL (low-density lipoprotein). This continues to float through your body and pieces are taken up by cells.

Your body makes HDL (high-density lipoproteins) to remove cholesterol from cells and bring it back to the liver to be either recycled or to be disposed of. If you read my previous post you can see an instance where your body would need to collect some cholesterol.
