Endocrinology/Carrier proteins
From PhysioWiki
Mostly see lecture 7 objectives for coverage of the carrier proteins.
The gist is that lipid-soluble hormones tend to be bound to carrier proteins to increase their solubility in plasma and prolong their half-lives. Most hormones have their own carrier proteins. Those that don't are bound to other, perhaps unexpected, carriers such as albumin.
Hormones that bind albumin:
- aldosterone (50% bound)
- testosterone (also binds TeBG)
- retinoic acid
- estrone
Hormones that bind TeBG:
- estradiol
Hormones that bind CBG:
- cortisol
- progesterone
