Proteins Flashcards
1
Q
Some roles of proteins in the body include:
A
- Hormones that control biological processes
- Structural components in cell membranes, muscles, hair
- Antibody molecules of the immune system
- Transport of substances across cell membranes/around the body
- Enzymes that catalyse specific biochemical reactions
2
Q
Primary structure can be described as:
A
- The sequence of amino acids
3
Q
What type of bonding is involved in the primary structure?
A
- Covalent bonding between C and N of carboxyl and anime to form amide/peptide link
4
Q
Secondary structure can be described as:
A
- Coiling and pleating of sections of a protein
5
Q
What type of bonding is involved in the secondary structure?
A
- Hydrogen bonds between -C=O and -N-H on different peptide links
~ Specifically the O and the H
6
Q
Tertiary structure can be described as:
A
- The overall 3D shape of a protein caused by bonds between R groups
7
Q
What types of bonding are involved in the tertiary structure?
A
- Hydrogen bonds
- Covalent bonds
- Ion-Dipole bonds
- Dipole-Dipole bonds
- Dispersion Forces
8
Q
Quaternary structure can be described as:
A
- Proteins comprised of two or more polypeptide chains
9
Q
What type of bonding is present in quaternary structures?
A
- Dispersion or other bonds between molecules
