Examples of drug being bound to lipoprotein
Plasma protein binding refers to the degree to which medications attach to proteins within the blood. A drug's efficiency may be affected by the degree to which it binds. The less bound a drug is, the more efficiently it can traverse or diffuse through cell membranes. Common blood proteins that drugs bind to are human serum albumin, lipoprotein, glycoprotein, and α, β‚ and γ globulins. WebMar 22, 2024 · Lp(a) is a type of low-density lipoprotein in which a large glycoprotein, apolipoprotein(a) (apo(a)), is covalently bound to apolipoprotein B by a disulfide bridge . …

Lipid transport. Absorbed lipids are transported in chylomicrons via the lymphatic system into the bloodstream, where they reach the liver, peripheral tissues (which have LDL receptors) and adipose tissue (storage).
WebThe binding of drugs to proteins is an important pharmacokinetic parameter. Many methods are available for the study of drug protein binding phenomena and there are also many ways to interpret the binding data. Although much emphasis has been placed on the binding of drugs in the plasma, binding also takes place in the tissues. WebAug 23, 2024 · By Dr. Liji Thomas, MD.

WebMar 22, 2024 · Lp(a) is a type of low-density lipoprotein in which a large glycoprotein, apolipoprotein(a) (apo(a)), is covalently bound to apolipoprotein B by a disulfide bridge . The apo(a) chain contains five cysteine-rich domains known as "kringles" . The fourth kringle is homologous with the fibrin-binding domain of plasminogen, a plasma protein that ... WebThe logic is as follows: Coadministration of drugs can result in a highly bound drug displacing a less avidly bound drug from its binding sites. This leads to greater amounts of free, nonprotein-bound, drug available for distribution to the sites of action. ... There are few examples where the above events have been documented to occur with ...
