Final answer:
The lipoprotein that forms when chylomicrons lose most of their triglycerides is Low Density Lipoprotein (LDL).
Step-by-step explanation:
The lipoprotein formed when muscle and adipose tissue remove most of the triglycerides from chylomicrons is Low Density Lipoproteins (LDL). After chylomicrons transport dietary triacylglycerols through the bloodstream, the enzyme lipoprotein lipase hydrolyzes the triacylglycerols into free fatty acids and glycerol, which can be used by cells for energy or stored in adipose tissue as fat.
The remaining chylomicron remnants, which are now depleted of much of their triglyceride content, are taken up by the liver cells and recombined with proteins to form LDLs. LDLs carry cholesterol and phospholipids to various tissues throughout the body and are crucial for cellular functions.
