match the following fat carriers with their descriptions:
made in intestinal cells after fats have been absorbed, released to lacteals
LDL
made by the liver, carry cholesterol to cells of the body, considered "bad" if there are too many
HDL
made by the liver, carry cholesterol back to the liver, considered "good"
all lipoproteins (chylomicrons, HDLs, LDLs, VLDLs)
composed of phospholipids and proteins arranged in a sphere, which trap fat-soluble substances inside for transport through the blood
chylomicron
Homework Answers
- made in intestinal cells after fats have been absorbed, released to lacteals - chylomicron
Explanation: The chylomicron is synthesized in the intestinal cells whereas other lipoproteins, HDLs, LDLs, VLDLs are synthesized in liver. Chylomicron functions to carry the lipids from the intestine to other part of the body.
- made by the liver, carry cholesterol to cells of the body, considered "bad" if there are too many - LDL
Explanation: The low density lipoprotein or LDL is considered as 'bad' if the concentration is high in the blood. They are synthesized in liver and the key function is to carry cholesterol from liver to other parts of the body through blood.
- made by the liver, carry cholesterol back to the liver, considered "good" - HDL
Explanation: HDL or high density lipoprotein is referred to 'good' cholesterol and the key function of it is to carry cholesterol molecules from different parts of the body to the liver.
- composed of phospholipids and proteins arranged in a sphere, which trap fat-soluble substances inside for transport through the blood - all lipoproteins (chylomicrons, HDLs, LDLs, VLDLs)
Explanation: The lipoproteins are composed of lipids and protein and the primary function is to transport the cholesterol molecules via blood, plasma or extracellular fluid. Lipoproteins has a single phospholipid layer arranged as a sphere and inside the sphere the hydrophobic lipids are enclosed. The protein called apolipoproteins re embedded within the phospholipid layer.

Which one of the following statements about chylomicrons is correct? a. Chylomicrons are made inside intestinal cells and secreted into lymph. b. The core of chylomicrons contains triacylglycerol and phospholipids. c. Chylomicron remnants differ from chylomicrons in that they are smaller and contain a lower proportion of triacylglycerol and a higher proportion of cholesterol. d. Chylomicrons are taken up by the liver.
