Peroxisomes hold on to enzymes that require oxygen (oxidative enzymes). Lysosomes have enzymes that work in oxygen-poor areas and lower pH. Peroxisomes absorb nutrients that the cell has acquired. They are very well known for digesting fatty acids. They also play a part in the way organisms digest alcohol (ethanol). Because they do that job, you would expect liver cells to have more peroxisomes than most other cells in a human body. They also play a role in cholesterol synthesis and the digestion of amino acids. Creating Hydrogen Peroxide Peroxisomes work in a very specific way. Their enzymes attack complex molecules and break them down into smaller molecules.
The liver is central to the regulation of cholesterol levels in the body. Not only does it synthesize cholesterol for export to other cells, but it also removes cholesterol from the body by converting it to bile salts and putting it into the bile where it can be eliminated in the feces. Two types of lipoproteins are triglyceride-rich: the chylomicrons and VLDL. 2  Chylomicrons are synthesized by enterocytes from lipids absorbed in the small intestine. 3  VLDL is synthesized in the liver. 4  The function of these lipoproteins is to deliver energy-rich triacylglycerol (TAG) to cells in the body (pink pathway).
