In order to define cholesterol metabolism we ougth to explain several notions for a better understanding. The effects, causes and possible problems that may be related to cholesterol require special attention. What do we understand by cholesterol? Medical dictionaries explain that this fat normally found in blood, results from eating animal-based foods. This substance is processed by the liver and it is an essential building block for healthy cells and nerves while it also serves to producing some hormones. However, the growth of the cholesterol level above the normal level presents high health risks for the heart and the circulatory system. Thus, this body fat is useful in moderate concentrations. The other notion to present in connection with cholesterol metabolism is obviously metabolism. All the chemical reactions that happen in the body are known as metabolism. To get into more detail, there are two types of metabolism: building up – anabolism, and breaking down – catabolism. With anabolism, small molecules create large ones, amino acids turn into protein. Obviously catabolism involves the reversed process, larger molecules (for example glycogen) get broken down into smaller ones (like glucose). Cholesterol metabolism is the sum of the catabolic and anabolic processes involved in synthesizing and degrading the cholesterol in the body. Serum cholesterol level increases when it is ingested and very quickly absorbed. Besides the liver, the ability to synthesize cholesterol is specific to all the body tissues. The more cholesterol you consume, the less it is processed by the body. The cholesterol removal from the body is done by bile excretion after it is broken down in the liver. There is a combination of factors that lead to increased cholesterol levels. Thus, A sedentary life style, an improper diet, a genetic predisposition, topped by weight gain become an extreme drawback for cholesterol metabolism. High blood pressure, diabetes, hypothyroidism and other health problems can also be a cause for high cholesterol levels. In some cases it is simply the liver which cannot accomplish its tasks. If you have a family history of high cholesterol, watch your health more carefully. Unfortunately for those who are predisposed genetically to elevated cholesterol levels, even the toughest low-fat or no-fat diets are of no much use. Medication can surely help. In other situations, a proper diet and a lot of physical activity can do much good. How to Boost Metabolism? Resell Ebook Ebooks Resell Metoblika#@34 Related posts:
