Agree entirely that all answers should be carefully checked before putting any weight on them.
With that said, I asked it about myself and got what might be described as a glowing obituary. Aw, gee.
But then I asked it a random question I'd never specifically thought of before:
"does any molecule naturally found in humans contain a benzene ring?"
(Brief pause)
"Yes, several molecules naturally found in the human body contain a benzene ring. Here are some key examples:
Amino Acids
Two essential amino acids found in humans contain a benzene ring: Phenylalanine: This amino acid features a benzene ring attached to an alanine side chain. It's crucial for the synthesis of other important molecules in the body. Tyrosine: Derived from phenylalanine, tyrosine has a benzene ring with an additional hydroxyl group. It's a precursor for several neurotransmitters and hormones.
Neurotransmitters
Several neurotransmitters in the human body incorporate a benzene ring: Dopamine: This important neurotransmitter contains a catechol group, which is essentially a benzene ring with two adjacent hydroxyl groups. Norepinephrine and Epinephrine: Both of these catecholamine neurotransmitters/hormones feature a benzene ring in their structure. Serotonin: This neurotransmitter, crucial for mood regulation, contains an indole group which includes a benzene ring fused to a pyrrole ring.
Other Biomolecules
Estrogen: The female sex hormone estrogen contains a benzene ring as part of its steroid structure. Thyroid Hormones: Both thyroxine (T4) and triiodothyronine (T3) contain benzene rings in their molecular structure.
It's important to note that while these molecules contain benzene rings, they are not the same as the toxic compound benzene itself. The benzene ring is a fundamental structural unit in organic chemistry, and its presence in a molecule doesn't necessarily imply the same properties or toxicity as pure benzene. These naturally occurring molecules play crucial roles in various physiological processes in the human body.
Accurate, as far as I recall (I would especially need to cross-check the neurotransmitter structures, but the rest are correct iirc.)
But it's as if you took put three or four top medical students in a room for ten minutes, and even then I'm not sure they would come up with all of these.
Just wow. Head and shoulders above the multiple sites of widely-varying quality that DuckDuckGo / Google would serve up.
(And the footnotes!)
Thanks again, Jim.
