Biological Molecules

Question 1

What bonds do carbohydrates form?

Answer 1

Peptide bonds

Question 2

What are the monomers of carbohydrates?

Answer 2

Monosaccharides

Question 3

What are two monomers called when they join together?

Answer 3

Disaccharides.

Question 4

Glucose + glucose =

Answer 4

Maltose.

Question 5

Glucose + fructose =

Answer 5

Sucrose

Question 6

Glucose + galactose =

Answer 6

Lactose.

Question 7

What bonds do starch molecules form? What structure do they then form?

Answer 7

Alpha 1, 4 glycosidic bonds
Alpha 1, 6 glycosidic bonds
They form branched structures which allows hydrolysis of glucose.

Question 8

What bonds does glycogen form? What structure does this then form?

Answer 8

A 1, 4 glycosidic bonds and 1, 6.
Highly branched structure which allows the rapid hydrolysis of glucose.

Question 9

What bonds do cellulose form? What structure does this then form?

Answer 9

Cellulose forms Beta 1, 4 glycosidic bonds which leads to straight chains running parallel to each-other and forms hydrogen bonds between adjacent chains. These form microfibrils.

Question 10

What are triglycerides made of?

Answer 10

One glycerol and three fatty acid molecules.

Question 11

What bonds do lipids form and during what type of reaction?

Answer 11

Ester bonds during condensation reactions.
