One of the most commonly cited studies on chitosan by the marketers and manufacturers of chitosan-based products is the 1994 ARS Medicina (Helsinki) Report. In this study, it was found out that test subjects lost eight percent of body fat and reduced cholesterol by thirty-two percent in four weeks. Secondly, there are various studies on chitosan which revealed that the substance lowers plasma cholesterol and triglycerides and improved the HDL cholesterol level. Working mechanism of this supplement is same as that of many other Chitosan containing products but differs in resulting effects. Obese people can get the most favorable and high rated results by making use of chitosan contrasting to its counterparts. Moreover, when overweight individuals take this supplement along with diet having lower calorie then it will surely lower the fat you intakes. At its most basic level, chitosan is a substance found in the shells of crustaceans, like crabs, lobsters and shrimps. It is extracted and taken in a form of supplement with meals and believed it encourages weight loss by binding to fat molecules, preventing the body from absorbing fat. However, whether chitosan is safe and helpful as a diet aid still remains controversial. After that, it was in 1878 while Ledderhose recognized chitin to be composed of glucosamine as well as acetic acid; it was not in fact until 1894 that Hoppe-Seyler identified the oriented chitin, chitosan. In the beginning of twentieth century, a number of inquiries and searches considered chitosan as their theme of schoolwork. The reason behind is that this Chitosan containing product offers 5-10 times greater effect on fat excretion in contrast to many other fat burning products. People who really want to improve their health profile need to control calorie rate in their daily diet plans. Chitosan plus is the best option they can bring into play for maintaining low-calorie along with high fiber diet. Chitosan chemistry involves numerous biomedical applications whenever it is going to be discussed. Following are some of the most common biomedical applications involving the use of Chitosan. Wound healing Tissue engineering Tissue repair Local delivery of cells etc Analysis of Chitosan chemistry revealed that it is made up of N-deacylation, which is a chitin molecule.
