What is Lipid Metabolism?

Metabolism is the sum of chemical reactions/processes which occur in living bodies and whose aim is to maintain life; this means growing, reproduction, maintaining the organisms’ structures and responding to their environments adequately. There are two main metabolic stages: anabolism on the one hand uses energy to make up cell components such as proteins and nucleic acids; on the other hand there is catabolism through which organic matter is broken down. The metabolic rate, or the speed at which metabolism performs its duties, is an important factor for determining the amount of food necessary to the body in terms of substances, while it also eliminates those that are not good for the system. Living organisms are made up of three main types of molecules: lipids or fats, amino acids and carbohydrates. The lipid metabolism is relevant for the health condition of the system.

Lipids or fats are the most diversified group of molecules or biochemicals. The lipids’ main uses are both as part of biological membranes (for example the cell membranes) and as source of energy. They usually dissolve in organic solvents (such as benzene and chloroform). They contain fatty acids and glycerol. Steroids such as cholesterol are also a major group of lipids that are produced in the cells. Metabolism in general and lipid metabolism as well, is carried out by means of the chemicals called enzymes, which are created by the body. Genetic abnormalities may cause some problems in the function of enzymes, which means that the ability to break down fat will be impaired.

One serious set of disorders caused by weak enzyme activity is that manifested in lipid metabolism. The fat that accumulates in the body is under constant transformation under the action of enzymes. The purpose is to balance the energy needs of the body with the available food. When the enzymes specialized in breaking down the fatty substances in the body do not work well any more, then, the toxins or residues that accumulate put an immense pressure on the system. These lipid metabolism disorders are called lipidoses. Other abnormalities which don’t allow the body from turning fats into energy lead to ailments that are called fatty acid oxidation disorders. Obesity or the excessive fat accumulation in the tissues is one condition caused by a deficient lipid metabolism. Excessive caloric intake may be the root of the problem or just the tip of the iceberg for such situations. Anyway, there are ways of tackling with lipid metabolism disorders withing reach. You only have fight against the condition.
