The enzyme trypsin hydrolyses proteins to amino acids. Trypsin does not function when the pH is very low as its 3D shape would be changed.
What explains this change in 3D shape?
Hydrogen ions attach themselves to negatively charged R groups.
2 )
Hydrogen ions disrupt disulfide bonds.
3 )
Hydrogen ions increase hydrogen bonding between amino acids.
4 )
Hydrogen ions reduce the affinity of hydrophilic R groups for water.
