Q. The characteristic strong absorbance of 280nm of proteins is due to
- All amino acids can absorb at 280nm
- Only Tryptophan and tyrosine can absorb at 280 nm
- Tryptophan is responsible for the absorbance
- Tryptophan, tyrosine and phenylalanine can absorb at 280 nm
Answer: Tryptophan, tyrosine and phenylalanine can absorb at 280 nm
