Clinical Biology

The following are the functions of cholesterol EXCEPT

• Bile acid synthesis

• Steroid hormone synthesis

• Membrane fluidity

• Thyroid hormone synthesis

Bile acid is derived from

• Cholesterol

• Amino acids

• Fatty acids

• Bilirubin

The following are plasma lipoproteins EXCEPT:

• Chylomicrons

• Very low density lipoproteins (VLDL)

• Low density lipoproteins (LDL)

• Very high density lipoproteins (VHDL)

• High density lipoproteins (HDL)

Triglyceride is

• Water soluble

• Water insoluble

• Soluble in water at elevated temperature

• Partially soluble in water

Draw a structure of triglycerides

Functions of lipids in the diet are to:

• Provide fat essential for the body function

• Transport water-soluble vitamins

• Promote growth and repair of tissues

• Maintain fluid balance

Lipids are supplied in large quantities in the diet by

• Fats, oils, meats, and nuts

• Cereals, fruits, vegetables, and breads

• Deep green and orange vegetables

• Green pepper, broccoli, and citrus fruits

The class of lipoproteins that is beneficial to atherosclerosis is:

• Low density of lipoproteins

• Very low density of lipoproteins

• High density of lipoproteins

• Chylomicron

High content of triglycerides are seen in

• LDL

• HDL

• VLDL

• Chylomicrons

Dietary fats after absorption appear in the circulation as

• HDL

• VLDL

• LDL

• Chylomicrons
