Extensive Definition
A microbody is a cytoplasmic organelle of a more
or less globular shape that comprises degradative enzymes bound
within a single membrane. Microbodies are specialized as containers
for metabolic activity. Types include peroxisomes, lysosomes, glyoxisomes, glycosomes and Woronin
bodies.
Peroxisomes
contain enzymes of b-oxidation
(break down fats and produce Acetyl-CoA), as
well as enzymes of many other important pathways like amino acid
and bile acid metabolism, oxidation/detoxification of various
harmful compounds in the liver (ex. alcohol).
Glyoxysomes are
found in germinating seeds of plants as well as in filamentous
fungi. Glyoxysomes are peroxisomes with additional function -
glyoxylate
cycle.
Glycosomes,
besides peroxisomal enzymes, also possess glycolysis enzymes and
are found in kinetoplastida like
Tripanosoma.
Woronin
bodies are special organelles found only in filamentous fungi.
One established function of Woronin bodies is the plugging of the
septal pores after hyphal wounding, which restricts the loss of
cytoplasm to the sites of injury.
