Hormones in the blood of humans are souble in water... but why?

Not all hormones are soluble in water. Some hormones require carrier protiens such as thyroid hormone. Some other hormone are steroid based and therefore lipophilic such as estrogen, testosterone and cortisol. These can easily diffuse through cell membranes (phospholipid bilayer) but there are also many hormones that are polypeptides and the majority of these are water soluble and polar compounds. Many hormones that are not soluble in water require a carrier protein to increase solubility.

They are soluble due to their shape and terminal OH groups.
The reason that they are water soluble is so they travel more quickly through tissue spaces, which are predominantly water based. Although they travel via the blood, their actions are predominantly on tissue and organs at the cellular level. So they need to get there via the interstitial spaces. Having them water soluble increases the speed of transfer. Fat soluble substances won't travel fast enough.

hormones are globular protein.
they have OH groups pointing outwards the molecules.
These OH groups will form hydrogen bonds with water.
Water molecules 'hold' these hormones molecules, so they dissolve.
