What Is HDL Cholesterol?
1. Description
High density lipoprotein cholesterol (HDL-C) that consists of mainly cholesterol, protein, and phospholipid is both produced and secreted by the intestine and liver. HDL-C have multiple surface proteins. Those with Apo-A1 and Apo-A2 proteins are those secreted from the liver. The synthesis of Apo-A1 is required for the production of HDL-C. Being the smallest of the lipoprotein particles, it is also the densest.
Cholesterol is generally transported to the liver, ovary, testes, and adrenals via several pathways. This is important for the production of steroid hormones. HDL has been found to be biologically effective as it helps to inhibit the aggregation of platelets, inflammation, coagulation, and oxidation. All these attributes contribute to the protection from atherosclerosis.
