HECO 1322 Exam 2 Questions with Correct
Answers
A low risk of cardiovascular disease correlates with high blood levels of
High-density lipoproteins (HDL)
A common feature of the plant sterols is they
inhibit absorption of dietary cholesterol
A major cause of rancidity of lipids in foods is exposure to
heat and oxygen
According to the Dietary Guidelines, what should be the maximum daily intake of
cholesterol on a 2500-kcalorie diet
300 mg
According to the DRI, what is the upper limit of fat (g) that may be consumed by a
healthy person requiring 3000 kcalories per day
117
Which dietary fatty acid has been found to raise blood cholesterol level by the least
amount
stearic
In comparison to a low-density lipoprotein, a high-density lipoprotein contains
less lipid/more protein
The oils found in walnuts, soybeans, flaxseed, and wheat germ represent a good source
of preformed
, linolenic acid
What information about the fat content is contained on a food label?
Total fat, saturated fat, trans fat, and cholesterol..... Compare products..... % Daily Value vs.
% kcalories from fat
What is the function of lipoprotein lipase?
Hydrolyzes blood triglycerides for uptake into cells
What are the methods used by food processors to stabilize the lipids in food products?
Refrigeration
What is the function of adipose cell hormone-sensitive lipase?
hydrolyzes triglycerides to provide fatty acids for other cells
What is an example of enterohepatic circulation?
Recycling of bile from the intestine to the liver
What are the features of cis-fatty acids and trans-fatty acids?
A cis-fatty acid has its hydrogens on the same side of the double bond; cis molecules bend
into a U-like formation. Most naturally occurring unsaturated fatty acids in foods are cis./A
trans-fatty acid has its hydrogens on the opposite sides of the double bond; trans molecules
are more linear. The trans form typically occurs in partially hydrogenated foods when
hydrogen atoms shift around some double bonds and change the configuration from cis to
trans.
What tissue contains special receptors for removing low-density lipoproteins from the
circulation?
