<prompt> The human plasma lipoprotein containing the highest percentage of triacylglycerol by weight is?LDLChylomicronsVLDLHDL  <response>: Ans. is b i.e., ChylomicronesoMaximum triglyceride content - ChylomicronsoMaximum exogenous triglyceride - ChylomicronsoMaximum endogenous triglyceride - VLDLoMaximum cholesterol content - LDLLipoproteinsoLipoproteins serve to transport the lipid in circulation. As the name suggests, lipoproteins contain lipids and protein. Lipid contents are cholesterol ester, cholesterol, phospholipid and triacylglycerol triglyceride. Protein moiety of a lipoprotein is known as apolipoprotein or apoprotein designated as apo -oFour major types of lipoproteins are:-1 Chylomicrons:-These are principal form in which dietary lipids exogenous lipids are carried from intestine to liver.2 Very low density lipoproteins VLDL:-These are triglyceride rich particles and transport endogenous triglyceride from liver to peripheral tissue.3 Low density lipoprotein LDL:-These are cholesterol rich particles and are the major source of cholesterol to peripheral tissues.4 High density lipoprotein HDL:-They transport cholesterol from peripheral tissues back to liver reverse cholesterol transportComposition of plasma lipoproteins ChylomicronVLDLLDLHDL1.
