Question
The primary function of VLDL particles is to carry these compounds from the liver to the peripheral tissues. For 10 points each:
[10e] Name this class of lipids, which consist of three fatty acid chains linked to a three-carbon backbone.
ANSWER: tri·glycerides [or triacylglycerols]
[10h] Triglycerides in VLDL particles are exchanged with these lipids by a namesake “transfer protein.” These very hydrophobic lipids are synthesized by an enzyme called either PCAT (“P-cat”) or LCAT (“L-cat”).
ANSWER: cholesteryl esters [accept answers referring to esterified cholesterol or esters of cholesterol; prompt on esters; reject “cholesterol” alone]
[10m] The surfaces of nascent VLDL particles express the “B-100” subtype of these proteins, which have many uses in lipid transport and metabolism. A polymorphism in the “E” subtype of these proteins has been correlated with increased risk of Alzheimer's disease.
ANSWER: apo·lipo·proteins [prompt on ApoE4; reject “lipoproteins”]
