Protien Structure Flashcards
(4 cards)
1
Q
Can alpha - helixes be found in hydrophobic environments like membrane protiens
A
Yes
As the side chains of the amino acids forming the helix are pointing outwards away from the helix, and they determine the hydrophobic or hydrophilic nature
2
Q
What are the chemical bonds involved in a beta pleated sheet
A
Hydrogen bonds between CO- and NH- group
Between non-adjacent polypeptide backbones
3
Q
Can alpha helix’s interact with each other
A
Yes
Two or more can wind to form a super helix/ coil-coiled structure
4
Q
What bonds stabilise the alpha helix in a protein
A
