Lipoprotein (a) - Lp(a)
Clinical Background:
Lipoprotein (a) is composed of an LDL‑like particle to which the lipoprotein (a)‑specific apolipoprotein (a) is bonded by a disulfide bridge. Apolipoprotein (a) is highly homologous to plasminogen....
Lipoprotein (a) is composed of an LDL‑like particle to which the lipoprotein (a)‑specific apolipoprotein (a) is bonded by a disulfide bridge. Apolipoprotein (a) is highly homologous to plasminogen. Lipoprotein (a) is a cholesterol‑rich lipoprotein which is synthesized in the liver independently of triglycerides and is not subject to the influence of age or diet.
Independent prospective risk factor for coronary heart disease.
