Chylomicron remnants are small particles formed in the bloodstream after chylomicrons have delivered dietary fats to tissues. Chylomicrons are lipoproteins that transport fats from the intestines to various parts of the body. Once they release their fat content, the remaining particles, known as chylomicron remnants, are taken up by the liver. These remnants are rich in cholesterol and other lipids. The liver processes them, which helps regulate lipid levels in the body. Proper handling of chylomicron remnants is important for maintaining healthy cholesterol levels and preventing conditions like atherosclerosis.
