B1.2 Proteins - tertiary structure and polarity Flashcards
1
Q
Hydrophilic (easily interact with water)
A
Polar
2
Q
Hydrophobic (repel water)
A
Non-polar
3
Q
Contain polar R-groups that can form hydrogen bonds
A
Polar
4
Q
Contain non-polar R-groups made of hydrocarbons
A
Non-polar
5
Q
Typically found on the surface of proteins (polar/non-polar amino acids)
A
Polar amino acids
6
Q
Typically found on the inside of a protein
A
Non-polar amino acids
7
Q
Describe globular proteins
A
Polar amino acids on the outside, non-polar on the inside
8
Q
Describe integral proteins (embedded in the cell membrane)
A
-non-polar inside the membrane as phospholipid tails are also non-polar so they attract each other
-polar inside and outside the membrane as cytoplasm (inside) and extracellular fluid (outside) both contain water
