Primary, Secondary, Tertiary And Quaternary Structure Flashcards
1
Q
Define: secondary structure
A
The shape that amino acid chains turn into due to hydrogen bonding between individual amino acids Alpha helices (spirals) Beta sheets (s shape) Random coils
2
Q
Define: primary structure
A
The amino acid sequence of a peptide
3
Q
Define: tertiary structure
A
The way that secondary structures join to form a protein
Held in place by peptide bonds
4
Q
Define: quaternary structure
A
When tertiary structures combine to form a more complex protein
5
Q
Do all proteins have a quaternary structure?
A
No
6
Q
Are all parts of the quaternary structure necessarily proteic?
A
No
