Albumin binds with all except ?
Ans. is ' d' i.e., Thyroxine Albumin is involved in transpo of several substances because of its predominantly polar nature. Nearly 40% of plasma calcium is bound-up with albumin. Other substances which are Bound-up and/or tranpoed by albumin are :? Free fatty acids Bilirubin Steroids Many nonpolar drugs Coming back to question Thyroxine also binds to albumin, but it is not the major transpo protein for thyroxin. Most of the thyroxine is transpoed by globulin. Thyroxine binding plasma proteins are :- Thyroxine binding globulin Major thyroid hormone binding protein Thyroxine binding albumin Thyroxine binding pre-albumin Thus, among the given options, thyroxine is the best answer.
Steroid
Calcium
FFA
Thyroxine
