glyoxysome

a type of organelle (microbody) containing ENZYMES of the GLYOXYLATE CYCLE. It is found in plants, particularly in germinating seeds.

In addition, peroxisomes and glyoxysomes, collectively referred to as micro bodies, are sub-cellular organelles that do not have an energy-coupled electron transport system, but instead contain flavine oxidases, which catalyse the substrate-dependent reduction of oxygen to [H.sub.2][O.sub.2].
Lipids can also serve as a source for the formation of membrane systems, such as those of the glyoxysomes, which require non polar lipids and phospholipids for their enlargement during seed germination (Chapman and Trelease, 1991).

These metabolites are normal products of natural redox reactions in mitochondrial respiratory and photosynthetic electron transport chains, peroxisomes and glyoxysomes. They degrade large macromolecules such as nucleic acid, proteins, lipids and chloroplast pigments.
