WebFirst of all, I think this video was a bit misleading in describing the structure of the chylomicron, which is only about 1-2% protein. Most of it is made of triglycerides, phospholipids, and cholesterol. Still though, the idea is that the outside of the chylomicron is polar, which allows it to be soluble in polar substances like plasma and lymph. WebHigh-density lipoprotein, or HDL: Made from a high proportion of protein with minimal triglycerides and cholesterol. When you eat, the small intestine takes the cholesterol and triglycerides from your food and packages them using chylomicrons to transport lipids into your bloodstream, and ultimately to your cell tissues.
