Question 1

The functional groups of amino acids include:

Answer 1

amino and carboxyl groups

Question 2

The inherited absence of lipoprotein lipase causes hyperchylomicronemia

Answer 2

Frederickson‘s type 1 hyperlipoproteinemia.

Question 3

contain principally triglycerides, but have a greater protein, phospholipid, and cholesterol content than chylomicrons

Answer 3

Very low-density lipoproteins (VLDL)

Question 4

protein and phospholipid content makes them charged so that they migrate just before the Bglobulins in electrophoresis

Answer 4

pre-B Lipoproteins

Question 5

markedly elevated in type IV hyperlipoproteinemia.

Answer 5

VLDL fraction

Question 6

contain mainly cholesterol, in contrast to the content of chylomicrons and VLDL, which is mainly triglyceride

Answer 6

Low-density lipoproteins (LDL)

Question 7

markedly elevated in type II hyperlipoproteinemia and is associated with a high incidence of atherosclerosis.

Answer 7

LDL fraction

Question 8

> contain mainly protein and phospholipid

> contain significant amounts of cholesterol, but have little triglyceride

Answer 8

High-density lipoproteins (HDL)

Question 9

The high protein, low triglyceride content makes them very dense

Answer 9

alpha-Lipoproteins

Question 10

Three main classes of lipids are found in biological membranes

Answer 10

Phospholipids
– glycolipids
– Cholesterol
