Peroxisome it is a term that is not part of the dictionary of the Royal Spanish Academy (RAE ). The concept is used to name a cytoplasm organelle which houses various oxidative enzymes as the peroxidase and the catalase .
Peroxisomes are surrounded by a membrane and are present in all eukaryotic cells . They were discovered by the English Christian de Duve (1917 -2013 ) and his team.
The oxidation from amino acids and fatty acids It is part of the functions of peroxisomes, which can have crystalline structures that are called crystalloids or nucleoids inside. They also take care of catabolize purines and remove hydrogen peroxide , a secondary product that originates when certain toxic substances are degraded (so it is said that peroxisomes, in the kidneys and in the liver, are involved in detoxification reactions ).
Spherically, the peroxisome does not have ribosomes attached to its structure or its own genome. Around it there is a single membrane, unlike what happens with chloroplasts and with the mitochondria .
Another interesting fact about peroxisomes is that they are able to change your enzyme composition according to various factors , such as environmental conditions or cell type. This makes a wide variety of these organelles exist.
A yeast which develops in an environment with a high level of fatty acids, to mention a case, presents peroxisomes larger than another yeast located next to carbohydrates. This is due to different oxidation needs.
