Although the term "lipid" is sometimes used as a synonym for fats, fats are a subgroup of lipids called triglycerides. Lipids also encompass molecules such as fatty acids and their derivatives (including tri-, di-, monoglycerides, and phospholipids), as well as other sterol-containing metabolites such as cholesterol. [6]
Other types of lipids found in the body are fatty acids and membrane lipids. Lipid metabolism is often considered the digestion and absorption process of dietary fat; however, there are two sources of fats that organisms can use to obtain energy: from consumed dietary fats and from stored fat. [5]
The surface of a curved lipid bilayer. Lipidology is the scientific study of lipids. Lipids are a group of biological macromolecules that have a multitude of functions in the body. [1] [2] [3] Clinical studies on lipid metabolism in the body have led to developments in therapeutic lipidology for disorders such as cardiovascular disease. [4]
This can be done in terms of the chemical elements present, or by molecular structure e.g., water, protein, fats (or lipids), hydroxyapatite (in bones), carbohydrates (such as glycogen and glucose) and DNA. In terms of tissue type, the body may be analyzed into water, fat, connective tissue, muscle, bone, etc.
On Chen, director of the lipid management program at the Stony Brook Heart Institute. “Lipoprotein(a) is determined genetically, and there's almost nothing that we can do to modulate that,” he ...
Fats and other lipids are broken down in the body by enzymes called lipases produced in the pancreas. Many cell types can use either glucose or fatty acids as a source of energy for metabolism. In particular, heart and skeletal muscle prefer fatty acids.
These disorders may be described as fatty acid oxidation disorders or as a lipid storage disorders, and are any one of several inborn errors of metabolism that result from enzyme or transport protein defects affecting the ability of the body to oxidize fatty acids in order to produce energy within muscles, liver, and other cell types.
Statins act on the liver to prevent the body from overproducing cholesterol and triglycerides. They can reduce “bad” cholesterol by between 30% and 50% , and lower triglycerides by 10% to 50%.
