Q

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

A
  • Histidine
  • Isoleucine
  • Leucine
  • Lysine
  • Methionine
  • Phenylalanine
  • Threonine
  • Tryptophan
  • Valine
16
Q

Give at least one types of protein and their functions

A
  • Structural proteins (Support)
  • Storage protein (Storage of amino acids)
  • Defensive proteins (Protection against diseases)
17
Q

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.

A

Polar side Chains

18
Q

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

A

Nonpolar side chains

19
Q

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

A

Acidic side chains

20
Q

An amine functional group produces a _____

A

Basic side chains

21
Q

An amino acid that has both amine and acidic functional groups has _____

A

Neutral side chains

22
Q

There are 20 types of amino acids, give one

V L G S T

A
  • Valine
  • Lysine
  • Glycine
  • Serine
  • Tyrosine
23
Q

Amino acid link to one another to form protein through

A

polymerization

24
Q

There are 4 levels of protein structure, what are these?

A
  • Primary
  • Secondary
  • Tertiary
  • Quaternary
