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.
Like lysosomes, peroxisomes are membrane-bound organelles that contain enzymes. Peroxisome enzymes produce hydrogen peroxide as a by-product. Peroxisomes are involved in at least 50 different biochemical reactions in the body. They help to detoxify alcohol in the liver, form bile acid, and break down fats.
