| umls-concept:C0023823 | skos:definition | MSH: A class of lipoproteins of small size (18-25 nm) and light (1.019-1.063 g/ml) particles with a core composed mainly of CHOLESTEROL ESTERS and smaller amounts of TRIGLYCERIDES. The surface monolayer consists mostly of PHOSPHOLIPIDS, a single copy of APOLIPOPROTEIN B-100, and free cholesterol molecules. The main LDL function is to transport cholesterol and cholesterol esters to extrahepatic tissues.,CSP: class of lipoproteins responsible for transport of cholesterol to extrahepatic tissues; they are formed in the circulation when very-low-density lipoproteins are degraded first to intermediate-density lipoproteins and then to LDL by the gain and loss of specific apolipoproteins and the loss of most of their triglycerides; LDL are taken up and catabolized by both the liver and extrahepatic tissues by specific receptor-mediated endocytosis.,NCI: A lipoprotein that carries cholesterol around the body, for use by various cells. LDL transports cholesterol to the arteries and increased levels are associated with | lld:umls |
