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.
There is a good and very readable article entitled âParsing Peroxisomesâ, about Lorenzoâs oil and peroxisomes in the Bulletin of the Howard Hughes Medical Institute (HHMI) at the following website: http://www.hhmi.org/bulletin/feb2008/features/parsing.html If this URL does not connect properly go to basic URL and then look in HHMI Bulletin, February 2008 issue for article entitled âParsing Peroxisomesâ.
