How are lipids carried - on lipoproteins in the blood because they are insoluble in water Proteins found on lipoproteins - apolipoproteins Density of lipoprotein with less lipid and greater protein - more dense Density of lipoprotein with more lipids and less protein - less dense Major bloodstream lipoproteins - chylomicrons, vLDL, LDL, HDL Chylomicrons - least dense of the lipoproteins and are triglyceride-rich particles that are formed in the intestine Function of Chylomicrons and where...

The cellular uptake of LDL increase intracellular cholesterol levels. This has which of the following impacts on de novo cholesterol synthesis? - Increases degradation of HMG-CoA reductase Dietary cholesterol is primarily transported in the body by which of the following lipoproteins? - Chylomicrons. Cholesterol and TG from diet are transported from intestine to liver via chylomicrons. The LDL receptor is also highly regulated in the cell. Which of the following proteins targets t...

4 principle avenues of communication in the body - 1. gap junctions (cytoplasm to cytoplasm) 2. neurotransmitter (synaptic cleft) 3. paracrines 4. hormones absorption of fats - 1. enter brush border cells through diffusion 2. enter the ER and recombined into triglycerides 3. in the golgi, triglycerides, cholesterol and phospholipids are packaged into protein coated chylomicrons 4. chylomicrons are released by exocytosis and enter lacteal (lymphatic capillary) acromegaly - a pituitary di...

chylomicrons produced in intestinal epithelial cells from dietary fat and carry triacylglycerol in blood VLDL produced in liver mainly from dietary carbohydrate and carry triacylglycerol in blood IDL Produced in blood from degradation of VLDL and is endocytose by liver or converted into LDL LDL Produced as remnant of IDL/VLDL and contains high concentration of cholesterol and cholesterol esters HDL Produced in liver and intestine, exchanges proteins and lipids wi...
