ubiquitous organelles in eukaryotes that participate in the
metabolism of fatty acids and other metabolites. Peroxisomes
have enzymes that rid the cell of toxic peroxides. They have a
single lipid bilayer membrane that separates their contents from
the cytosol (the internal fluid of the cell) and contain
membrane proteins critical for various functions, such as
importing proteins into the organelles and aiding in
proliferation. Like lysosomes, peroxisomes are part of the
secretory pathway of a cell, but they are much more dynamic and
can replicate by enlarging and then dividing. Peroxisomes were
identified as cellular organelles by the Belgian cytologist
Christian de Duve in 1967 after they had been first
