50

What compound is used to synthesize cholesterol

Acetyl coA

51

Where is cholesterol made

Liver

52

Where is excess cholesterol not needed by the body transported

Gallbladder

53

This excess cholesterol might accidentally precipitate out as what

Gall stones

54

Aldosterone

55

What steroid hormones regulates the conversion of proteins to carbohydrates

Cortisone
Cortisol

56

Emulsifier found in egg yolk

Lecithin

57

What kinds of lipids are found in the cell membrane

Phospholipid
Glycolipid
Cholesterol

58

Products of saponification of a fat

Glycerol
3 salts of fatty acids

59

Cholesterol is used to synthesize what three types of compounds

Steroid hormones
Vitamin D
Bile salts

60

What general structural feature do phosphatides share with soaps

Ionic end
Hydrophilic

61

What structural feature Is found in most prostaglandins

5 carbon ring

62

Functional group found in a saponifiable lipid which is not found in a nonsaponifiable lipid

Ester linkage

63

Lack of an enzyme to metabolize glycolipids may cause what diseases

Niemann pick

Gauchers

Tay-Sachs

64

Functions of fat in the body

Energy

Insulation

Protection of vital organs

65

Can wax be converted to soap

Yes but difficult

66

Difference between fat and oil

Oil is unsaturated fatty acid

67

Why do unsaturated fatty acids have lower melting points than saturated fats

Cis double bonds cause "bonds" = do not stack well

68

How do products of the acid hydrolysis and base hydrolysis of fat differ

Acid hydrolysis = fatty acids

Base hydrolysis =salt of fatty acid

69

Why does coconut oil (veggie oil) have a melting point similar to fats from animal sources

It has very few double bonds
