|Lipids and carbohydrates are the energetic molecules and one of the main components of the metabolic system. These molecules circulate in the blood stream and between the metabolic tissues and transfer energy throughout the body. They are degraded and release their energy in the form of Adenosine Triphosphate (ATP) to be used in anabolic reactions. Anabolic reactions are the energy consumer reactions for synthesis of molecules or energy storage. These include glycogenolysis, glycolysis, Tricarboxylic Acid (TCA, citric acid or the Krebs) cycle, electron transfer chain, and fatty acid beta oxidation and protein breakdown. Carbohydrates are the main energetic molecules that are consumed by active tissues like muscles. In excess consumption of carbohydrates, they are converted to lipid molecules to be stored in the adipose tissue for the time of starvation. This matter is one of the most important functions of the body in energy homeostasis. Lipid-carbohydrate interaction is one of the fundamental parameters in regulation of the energy metabolic system. Disturbance in the function of the adipose tissue as the main fat storage organ of the body leads to FAID and consequently metabolic disorders. In this review, the biochemical pathways of the main energetic molecule of the body (lipids) are summarized in such a way that researchers can follow the association between these pathways easily. Understanding these biochemical pathways will help biologists to comprehend the pathophysiology of metabolic diseases properly.
Scientific journal is a periodical publication intended to further progress of science, usually by reporting novel research. There are thousands of scientific journals in publication, and many more have been published at various points in the past. Most journals are highly specialized, although some of the oldest journals publish articles and scientific papers across a wide range of scientific fields. Scientific journals contain articles that are peer reviewed, to ensure that articles meet the journal's standards of quality, and scientific validity. The publication of the results of research is an essential part of the scientific method. If they are describing experiments or calculations, they must supply enough details that an independent researcher could repeat the experiment or calculation to verify the results. Each such journal article becomes part of the permanent scientific record.
