Catalase is an antioxidant enzyme commonly found in almost all living organisms. It is the hallmark enzyme of peroxisomes and accounts for about 40% of the total peroxisomal enzymes.
Catalase is found mainly in red blood cells and peroxisomes in certain tissues of the human body. For example, the liver has a high concentration of catalase, which helps the body convert hydrogen peroxide into water and oxygen, preventing the formation of carbon dioxide bubbles in the blood. In addition, catalase can break down substances such as ethanol, phenol, and formaldehyde.
Hydrogen peroxidase is produced by the body itself and is important for growth, development and metabolic activity. Sometimes in the white belt examination, there may be a positive result of catalase, usually due to the patient has vaginitis, resulting in the destruction of the vaginal flora and the positive results, the patient should consult the doctor in time for appropriate treatment.
The biological function of catalase is to promote the decomposition of hydrogen peroxide in cells, so that it will not produce further toxic hydroxyl radicals, thus protecting the functional role of the antioxidant enzyme system, which is also important for human growth and metabolic activities.
