Individuals with a fatty-acid metabolism disorder are unable to metabolize this fat source for energy, halting bodily processes. [1] Most individuals with a fatty-acid metabolism disorder are able to live a normal active life with simple adjustments to diet and medications. If left undiagnosed many complications can arise.
Ectopic fat is the storage of triglycerides in tissues other than adipose tissue, that are supposed to contain only small amounts of fat, such as the liver, skeletal muscle, heart, and pancreas. [1] This can interfere with cellular functions and hence organ function and is associated with insulin resistance in type-2 diabetes. [ 46 ]
Hormonal disorder due to the body's inability to properly metabolize fat; Increase in fat cells ; Enzymatic defect or a change in the surface of the cells that could prevent the breakdown of fat; Poor lymphatic drainage; Defective regulation of mitochondria in brown fat. Brown fat is responsible for causing heat in times of stress or cold.
Many affected individuals also have heart disease, often involving enlarged or diseased heart valves. Another lysosomal storage disease often confused with the mucopolysaccharidoses is mucolipidosis. In this disorder, excessive amounts of fatty materials known as lipids (another principal component of living cells) are stored, in addition to ...
A typical fat cell is 0.1 mm in diameter [2] with some being twice that size, and others half that size. However, these numerical estimates of fat cell size depend largely on the measurement method and the location of the adipose tissue. [2] The fat stored is in a semi-liquid state, and is composed primarily of triglycerides, and cholesteryl ester.
One product of fatty acid metabolism are the prostaglandins, compounds having diverse hormone-like effects in animals. Prostaglandins have been found in almost every tissue in humans and other animals. They are enzymatically derived from arachidonic acid, a 20-carbon polyunsaturated fatty acid.
Ketogenesis pathway. The three ketone bodies (acetoacetate, acetone, and beta-hydroxy-butyrate) are marked within orange boxes. Ketogenesis is the biochemical process through which organisms produce ketone bodies by breaking down fatty acids and ketogenic amino acids.
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] Vertebrates (including humans) use both sources of fat to produce energy for organs such as the heart to function. [6]
