Question 5

Beta structure creates what?

Answer 5

Stacks.

Question 6

Describe primary structure

Answer 6

The sequence of amino acids.

Question 6

Secondary structure.

Answer 6

Hydrogen bonds between hydrogens and oxygens in the polypeptide backbone

Question 7

Tertiary structure.

Answer 7

Folds into a 3D shape, determined by interactions with R groups.

Question 8

Quaternary structure.

Answer 8

2 or more polypeptides assemble to form larger protein molecules.

Question 9

Which polysaccharide allows for the most storage?

Answer 9

Glycogen.

Question 10

Describe saturated fatty acids.

Answer 10

No double bonds between carbons, it’s saturated with H atoms. Ex: animal fats, and they’re solid at room temp. Packed together tightly.

Question 11

Unsaturated fatty acids.

Answer 11

One or more double bonds in the carbon chain which means that it prevents it being packed together. Ex: plant oils.
