Catalase is an antioxidant enzyme commonly found in almost all living organisms, mainly in chloroplasts, mitochondria, endoplasmic reticulum of plants, liver and red blood cells of animals. It is the marker enzyme of the peroxisome, accounting for about 40% of the total peroxisomal enzymes. Catalase is a homotetramer composed of four polypeptide chains, each containing more than 500 amino acid ...
Some substances can easily interact with the oxygen in the air when exposed to the air, causing chemical changes in the substance. This is the process of oxidation. Sun exposure, air pollution, radiation, etc. will cause the human skin to produce a large amount of superoxide free radicals, and its strong oxidizing ability will accelerate the speed of skin oxidation, and may even cause serious ...
A team of international researchers, led by Professor Zhu Yongguan of the Institute of Urban Environment, Chinese Academy of Sciences, said the estuaries — areas where land, fresh water, and seawater meet — contained both antibiotic agents and antibiotic-resistance genes, which entered the waterways via human activity. Water along roughly 4,000 kilometers (about ...
As regulators focus in on the critical quality attributes (CQAs) of biotherapeutics, what can biopharmaceutical labs in late development or QC do to increase confidence in their bioseparations assays – other than to run additional orthogonal assays? Many labs are finding the answer in mass detection, specifically with the ACQUITY QDa Detector from Waters. Here are three ways that mass ...
Because children have more delicate immune systems than adults, water contaminants pose a more serious threat to the young. Drinking only the highest quality water is one way that parents can contribute to keeping their children healthy, even before they are born. Pregnant women need to be especially careful of the water they drink. Certain levels of some water contaminants such as lead, nitrate ...
