Have only two fatty acids
Have a phosphocholine group instead of a third fatty acids
Consist of hydrophilic head and hydrophobic tail
Result in a bilayer arrangement found in cell membrane

Question 12

Amino groups:

Answer 12

Are organic molecules possessing both carboxyl and amino groups

cellulose

Question 26

aldehyde is :

Answer 26

An organic molecule with at least one functional group made up of a carbon double bonded to oxygen and the same carbon bonded to hydrogen and to a second
carbon

Question 27

cellulose:

Answer 27

Linear polysaccharide of hundreds to thousands of beta glucose monomers linked by a 1–4 glycosidic linkage. Make up cell walls in plants; a structural polysaccharide.

Question 28

glycemic index

Answer 28

A measure of how quickly levels of glucose in the blood rise after eating a particular type of food.

Question 29

glycogen

Answer 29

Storage polysaccharide made of α-glucose monomers in a highly branched helical form; found in the liver and muscle cells of animals and fungi

Question 30

amphipathic

Answer 30

A molecule that is hydrophobic at one end and hydrophilic at the other.

Question 31

phospholipids

Answer 31

Lipid made of two fatty acids, one glycerol, and one phosphate group; commonly associated with cell membranes.

Question 32

saturated fatty acids

Answer 32

Fatty acid containing no double bonds between carbon atoms in the carbon skeleton; hydrocarbon tail is straight in form.

Question 33

unsaturated fatty acids

Answer 33

Fatty acid containing one or more double bonds between carbon atoms in the carbon skeleton; hydrocarbon tail is kinked if the double bond is in the cis form.
