- •
Tyrosine photolysis proceeds through deamination, hydroxylation and dimerization.
- •
Dimerization could be linked to the photoinduced formation of tyrosyl radicals.
- •
New protogenic sites are formed by irradiation, compared to the parent amino acid.
- •
The irradiated material has higher copper complexation capacity than tyrosine.
- •
Humic-like substances derived from tyrosine could complex Cu in surface waters.
