So the logic below is apparently where my research has taken me. Someone please point out which reasoning step is false or reconcile the paradox.
1. Peptide hormones are water-soluble and diffuse through blood.
2. T3 and T4 are peptide hormones (synthesized from the amino acid tyrosine).
3. But, T3 and T4 require transport proteins to dissolve through blood.
My guess is that #1 is wrong. In other words, peptide hormones (like amino acids) are not necessarily polar. I'm just confused because I have heard #1 from numerous sources (including a Kaplan teacher).
Anyways, thanks in advance
