Triglycerides, Serum/Plasma


Triglycerides are part of the major forms of lipids found in plasma. They are formed in the intestinal mucosa by the esterification of glycerol and free fatty acids. They are then released into the mesenteric lymphatics and distributed to most tissues for storage. Triglycerides are the major constituents of stored lipids and make up to 95% of adipose tissue in humans.


Elevated levels of triglycerides are associated with a higher risk for atherosclerosis. High triglyceride levels and hyperlipidaemia can be inherited traits. In addition, elevations in triglyceride levels can be secondary to disorders such as diabetes, nephrosis, biliary obstruction and metabolic disorders associated with endocrine disturbances.
