Degradation of Protein/Amino Acids/Vitamins

I have been trying to search around and find some information on how fast degradation of certain supplements happen when stored in water. From what I can gather degradation happens primarily from oxidation or contact with oxygen. So what if a mixture that contains protein/amino acids/vitamins etc. is stored in water but sealed shut? Would degradation happen at a much slower pace?

I am struggling to really find any definitive answers so any help would be appreciated.
