Organic Compounds - Lipids

Question 1

Define Lipids

Answer 1

Lipids are non polar organic compound that contains carbon, hydrogen and oxygen atoms.
Molecular formula C15H31COOH
Non polar- hydrophobic

High ratio of hydrogen to oxygen

Question 2

What do lipids do for other nonpolar compounds?

Answer 2

Acts like a solvent.

Question 3

What is a basic monomer in lipids?

Answer 3

Fatty Acids

Question 4

What is a fatty acid?

Answer 4

Fatty acids are a lipid with hydrocarbon chains bound to a Carboxylic Acid group (COOH).
Can have 4-20 more carbon atoms.

Question 5

Define the structure of Saturated fatty acids

Answer 5

Saturated fatty acids don’t have any double bonds between any of its carbon atoms,. Carbon atoms are more saturated with hydrogen atoms. Found in ANIMAL fats.

Question 6

Define the structure for Monosaturated fatty acids

Answer 6

Monosaturated fatty acids have double bond between two carbons in its hydrocarbon chain, causes it to bend. (can’t pack together as tightly lower melting point.)

Question 7

Polyunsaturacted fatty acids

Answer 7

2 or more double bonds between carbon atoms. Lowest melting point.

Question 8

Triglycerides

Answer 8

A lipid consisting of other hydrocarbon rings attached to chemical groups.

Question 9

What are Steroids’

Answer 9

A lipid consisting of other 4 hy

Question 10
