Question 14

can serve as a protein on its own

Answer 14

polypeptide

Question 15

Protein synthesis is only possible if you have all of the amino acids necessary, and there are 9 of them

Answer 15

• Histidine
• Isoleucine
• Leucine
• Lysine
• Methionine
• Phenylalanine
• Threonine
• Tryptophan
• Valine

Question 16

Give at least one types of protein and their functions

Answer 16

• Structural proteins (Support)
• Storage protein (Storage of amino acids)
• Defensive proteins (Protection against diseases)

Question 17

Bonds are more polar when there is great electronegativity difference between the atoms. Function group such as acids, amides, alcohols, and amines exhibit this property; thus they impart polarity to the amino acid.

Answer 17

Polar side Chains

Question 18

These side chains have pure hydrocarbon alkyl or aromatic groups. The number of alkyl groups affect the polarity of the amino acid.

Answer 18

Nonpolar side chains

Question 19

One acidic functional group is enough to make an entire amino acid acidic

Answer 19

Acidic side chains
