Lipids: Essential to Our Body

Lipids can be described as hydrophobic molecules soluble in organic solvents (Berg, Stryer, & Tymoczko, 2010). Lipids are important because lipids are used to store energy, act as a structural component of cell membranes, and play an important role in the signal transduction pathway. There are several classes of lipids - fatty acids, triacylglycerols, phospholipids, glycolipids and steroids. Many people are hearing about fatty acids such as omega 3 and omega 6 fatty acids, or 'essential fats'.

Lipids are essential components of human organisms, most of which are hydrophobic and amphiphilic. Some lipids are fatty acids, cholesterol, steroid hormones, eicosanoids, bile salts and glycerophospholipids in the human body. The synthesis of these lipids is very important in metabolism. The main catabolic pathway of lipids is fatty acid oxidation (β oxidation), where fatty acid chains are broken down to acetyl CoA. In this article, we clearly explain the normal metabolic pathway of lipids in human cells. Then, diseases related to metabolic abnormalities in newborn babies are mentioned. Throughout the article, I analyzed the disease and showed symptoms and treatment.

Cholesterol is an essential lipid for human health (see LIPID). Cholesterol is an important component of every cell membrane in the body. In addition, the liver uses cholesterol to make bile acids and help digestion. The body also uses cholesterol to produce certain hormones including vitamin D and sex hormones. Cholesterol and triglycerides (another lipid) are the two major fat substances in the blood (see TRIGLYCERIDE). Cells can use triglycerides as energy, or they can be saved for later use. Physicians often measure levels of cholesterol and triglycerides in the blood to help determine the overall health status of the patient. High levels of cholesterol, especially including high levels of triglycerides, increase the risk of heart disease

Dyslipidemia is the third cornerstone of metabolic syndrome. This is an interlace abnormality in blood lipid level. Lipids consist of cholesterol, lipoprotein, chylomicron, low density lipoprotein, high density lipoprotein and triglycerides. Cholesterol may be best known among lipid families. It is generally believed that not all cholesterol is bad. Cholesterol is actually an essential nutrient for the human body (Thatcher 289). Lipoprotein is a carrier of all lipids. It transports lipids through the blood. Chylomicron is the largest lipid. They were fat at the top (Thatcher 289). The next is high density and low density lipoprotein. Low density lipoprotein is considered "bad cholesterol", but high density lipoprotein is used in the body to remove excess cholesterol. Finally, there are also triglycerides. Triglyceride is the reason why fat cells are compiled. They are directly related to obesity
