Microbodies, also called peroxisomes, are organelles found in the cytoplasm of eukaryotic cells. They are bound by a single membrane and contain proteins that are critical for various functions. Peroxisomes participate in the metabolism of fatty acids and other metabolites, and harbor enzymes that break down toxic peroxides. They also play a role in the production of bile acids and proteins. Certain diseases, such as adrenoleukodystrophy and Zellweger syndrome, can result from malfunctions of peroxisomes.
