crystalloid core in the center. -this is not always present and if it is absent makes identification of peroxisomes difficult. peroxisomes are mainly identified by their chemical composition, they are full of this enzyme.
All animal cells (except erythrocytes) and many plant cells contain peroxisomes, a class of small organelles (â0.2 â 1 Î¼m in diameter) bounded by a single membrane (see Figure 5-25c). (Glyoxisomes are similar organelles found in plant seeds that oxidize stored lipids as a source of carbon and energy for growth. They contain many of the same types of enzymes as peroxisomes as well as additional ones used to convert fatty acids to glucose precursors.)
