Question 1

Carbohydrate

Answer 1

Monomer: Monosaccharide
Polymer: Polysaccharide
Function: Short term energy storage

Elements: C,O,H
Functional Groups: Hydroxyl

Example: Starch

Question 2

Lipids

Answer 2

Monomer: Fatty acids
Polymer: Triglycerides, phospholipids.
Function: Long term energy storage

Elements: C,O,H (much higher H compared to carbohydrates)
Functional Groups: Carboxyl, Phosphate (if it is a phospholipid)

Example: Cholesterol

Question 3

Proteins

Answer 3

Monomer: Amino Acid
Polymer: Polypeptide
Function: Many (one example being enzymes to speed up reactions)

Elements: C,O,H,N, S* (not in every protein)
Functional Groups: Carboxyl, Amino.

Example: Hemoglobin

Question 4

Nucleic Acid

Answer 4

Monomer: Nucleotide
Polymer: Nucleic Acid (DNA or RNA)
Function: Genetic code

Elements: C,O,H,N,P
Functional Groups: Phosphate, Hydroxyl

Example: DNA

Question 5

Compare and contrast the structure of each of the biomolecule groups.

Answer 5

Proteins: Branch
Carbohydrates: Ring
Nucleic Acids: Ring
Lipids: Linear

Question 6

Compare and contrast the functions of each of the biomolecule groups.

Answer 6

The main comparisons are between lipids and carbohydrates as they both relate to energy. However, carbohydrates store energy short-term while lipids store energy long-term.
