What's the difference between hormones and proteins? I read somewhere that hormones can be derived from a protein, lipid or amino acids? I thought hormones were a type of protein though...

I know that insulin is a hormone but ti is also a globular protein. Can someone please help me make sense of this, I'm starting to burn out! Thanks

Hormones are chemical messengers in the body. Yes insulin is a peptide hormone meaning is a hormone derived from a protein. However other hormones are derived from other substances so not all hormones are protein. For example, testosterone is a steroid hormone meaning it is derived from cholesterol. I’m only an A-level student so I’m not entirely sure why different hormones are derived from different types of molecules, i just know that some hormones are proteins but others are derived from the types of molecules you have mentioned.

proteins are a type of hormone, there's also lipid hormones etc. i think it just depends on where they're produced. like insulin is a protein hormone because it's produced in the pancreas

Hi Bob (?),

Hormones are chemicals secreted by endocrine glands that are secreted DIRECTLY into the bloodstream and exert their effects in [mostly] sites remote from the gland.

Hormones are EITHER proteins/peptides OR steroids, NOTHIONG ELSE.

Protein hormones include [as already mentioned] insulin [a 56 amino acid peptide] and growth hormone - insulin, you might know, tends to lower blood glucose levels by:-
a) increasing glucose entry into cells
b) reducing gluconeogenesis [Greek neo = new; genesis = creation [as in bible] so production of new glucose, mainly from amino acids]
c) increasing glycogenesis [conversion of glucose to glycogen [stored in the liver and in muscles]
etc etc

Steroid hormones include the sex hormones [e.g. oestrogen and testosterone] and the adrenocorticosteroids. [hormones secreted by the adrenal gland [like a cap-shaped organ above each kidney] e.g. cortisol, which mediates the "biological clock" in our bodies.

Hope this helps!
Be safe!
