Hormones within a chemical class have the same function, but act on different substrates.
Hormones are chemical substances secreted by endocrine glands
The endocrine system produces chemical messengers called hormones. Examples of hormones include thyroxine, adrenaline, and estrogen.
Endocrine glands release hormones. These chemical messengers control body processes.
As far as I am aware, dopamine is a brain chemical not a hormone. It has a different biological job to a hormone.
Hormones. Fool.
All hormones are blood-borne.All hormones are "chemical messengers."
Different chemical classes of hormones are made from different substrates and are soluble in different solvents. Steroid hormones are synthesized from cholesterol and include: testosterone, aldosterone, cortisol, estradiol and progesterone. They are soluble in lipids (fat-soluble) and can therefore be administered orally. Other kinds of hormones, eg: tyrosine-based hormones and protein hormones, are made from different substances (eg: amino acids) and may be water soluble and therefore cannot be administered orally.
