Question 1: Why is there a color change when ferric iron is added to transferrin? I have read a few articles that state that there is a colour change when ferric iron (fe3+) is added to transferrin resulting in an absorbance maxima at 465nm. However they state that there is no colour change when ferrous iron (fe2+)is added. I was wondering why this is? Question 2: How do you determine if carbonate or bicarbonate is bound to transferrin? I have read a few articles that state that carbonate is bound to transferrin and others that state it is bicarbonate. How do you determine which it is or does it make a difference and I am being picky about somethin
