Chylomicron remnants are catabolised in Liver. | The half-life of these lipoprotein particles in the serum was studied in a group of control subjects and a group of subjects with previous acute pancreatitis 1992 Nov;12(4):386-96. doi: 10.1055/s-2008-1040408. Chylomicrons are a class of lipoproteins formed in the small intestine during the absorption of exogenous lipids. Here, it may 1) be removed directly by LDL receptors; 2) acquire additional apoE that is secreted free into the space, and then be removed directly by the LDL receptor-related protein (LRP); or 3) it may be sequestered in the space.

Plasma clearance and liver uptake of chylomicron remnants generated by hepatic lipase lipolysis: evidence for a lactoferrin-sensitive and apolipoprotein E-independent pathway. CD36 is involved in the uptake of long-chain fatty acids (LCFAs) in muscles and small intestines. Apolipoprotein E: Apolipoprotein E is synthesized in many tissues but the liver and intestine are the primary source of circulating Apo E. Apo E exchanges between lipoprotein particles and is associated with chylomicrons, chylomicron remnants, VLDL, IDL, and a subgroup of HDL particles. Firstly the triglyceride moiety is hydrolized and tissues are supplied with the released fatty acids. 2. Epub 2020 Sep 2. USA.gov. First, chylomicron remnants are catabolized at a nearly normal rate in familial hypercholesterolemic (FH) subjects;5 these individuals have either no ap B.E(LDLo receptor) s or defective apo In hepatocytes, retinyl esters are rapidly hydrolyzed to retinol, which is transferred to the endoplasmic reticulum and then binds to retinol‐binding protein (RBP, also known as RBP4), an extracellular retinol transporter 8 , 9 . Although specific assays for chylomicron remnants do not exist, plasma remnants could be assessed by measuring apoC-III or remnant-like particle cholesterol levels . Emul- 2174 Journal of Lipid Research Volume 38, 1997 by guest, on November 6, 2017 Intestinally derived chylomicron remnants (CM-r) are also thought to contribute to atherogenic dyslipidemia during insulin resistance. Hepatic removal appears to be accomplished by several overlapping mechanisms. As a result, a new particle called a chylomicron remnant is formed. Welcome to Sarthaks eConnect: A unique platform where students can interact with teachers/experts/students to get solutions to their queries. Chylomicron remnants arise from the hydrolytic action of lipoprotein lipase on chylomicrons, triacylglycerol-rich lipoproteins which enter the blood from the intestine after a fat-enriched meal [9,10]. Chylomicrons are the largest form of lipoproteins, containing triglycerides absorbed by the small intestine. Genetic remnants are rapidly catabolized and they exist in plasma at basis of this extreme phenotype are not completely eluci- relatively low concentrations; and (3) remnants are heteroge- dated. Triglyceride-rich lipoproteins as very low density lipoproteins and chylomicrons are snythesized by liver and intestine. Remnants are extremely atherogenic lipoproteins (3, 4). Chylomicron remnants, which contain most of the absorbed retinol 6, are mainly endocytosed by hepatocytes 7.
