Chapter 3, Problem 43P

Interpretation Introduction

Interpretation:

When ${\text{O}}_{\text{2}}$ binds to the Fe centre, it does so in an ‘end-on’ manner and give rise to a band in the IR spectrum at 1107 ${\text{cm}}^{\text{-1}}$, no absorption is present in the IR spectrum of gaseous ${\text{O}}_{\text{2}}$, these observations are to be rationalized.

Concept Introduction:

Haemoglobin is iron containing metalloprotein responsible for transporting ${\text{O}}_{\text{2}}$ in the bloodstream of mammals and is stored in the tissues in myoglobin.

Both haemoglobin and myoglobin are haem-iron proteins.
