Hill equation in Biochem

We are studying Myoglobin and Hemoglobin.

What do we use as "K" for the Myoglobin-Oxygen and Hemoglobin-Oxygen dissociation equations??

Does K change? I thought K was always constant. My book doesn't give a value for K and I can't find one on the internet. I'm obviously missing something in the concept.

Please help, thanks 🙂

Do you mean Kd ( the dissociation constant). This link may help:
