Can this type of structure describe Reality? I think so.
Does anyone else?

In Reality, the central system in an Amino Acid is a Carbon Ion.
Not the reality that the rest of us live in.

Just for the record.
You have falsely attributed your nonsense to me

I didn't say that.
In reality we have a pretty good idea how proteins work.

AC/BC/PC/C2B/C .Five peas in a pod. Or maybe one?. Whatever, you five do a lot of Criticising without, imho, often persuading the reader of your rightness.

btw K(C)riptid (see Wiki and translate from Indonesian)

In cryptozoology and cryptobotany, cryptids (from Greek: κρύπτω, translit. Krypto, meaning "hide") is a creature or plant that supposedly exists but is unknown to the scientific consensus and is often very hard to believe. [1] Famous examples of cryptids include the Yeti in the Himalayas and the Loch Ness monster in Scotland. Sometimes cryptids are also called "UMA", an acronym for Unidentified Mysterious Animals. The affix "crypt-" comes from Greek meaning "hidden" or "secret".

Disagree strongly. Alan and Bored Chemist have both made a valiant effort to restore truth to this thread, alas in vain.

My favorite T-shirt slogan:

Every disaster movie begins with someone ignoring a scientist.

Returning to the question, for the last 60 years I have been well paid to measure the energy of photons, thousands of clients think I'm right, and their patients have for the most part survived and prospered because sensible people believe me.

I see you edited your post, when I looked at it there were just "two peas in the pod". There are plenty more peas available to fill the pod to bursting and nobody to back up your false ideas. Give it up and learn some real science.

This is New Theories. You, I am guessing, would have advised Einstein simarly when he proposed his Theory of RElativity.

Real science begins (or in the case of relativity and quantum mechanics, ends) with what we already know, not by asserting that we don't know it.

True, this is the "new theories" subforum. Unfortunately I have yet to see any new theory here, only repetitive gibberish born of a lack of comprehension and puerile egotism.

Yet you keep on reading my posts. This is the definition of insanity.

I would have thought real science begins where mathemtics ends and computer science starts.The mathematics of quantum mechancs for example  has limitations that are transcended by quantum computing.

Alas, to wear the mantle of Galileo it is not enough that you be persecuted by an unkind establishment, you must also be right.

While I'm a bit younger than Alan, and the photons I measured were typically about a thousand times less energetic, I too made a career from measuring them.

Forty years ago I was handsomely paid to spray the environment with photons in the range of ~4 nano eV to ~4 micro eV. No measurement of photon energy, alas.

All sources were either xtal controlled directly or indirectly by pll. Of course the frequencies were measured, Alan, but I did not measure energies directly like BC and yourself. I still have the bk precision frequency counter from that era but it has become a bit erratic in operation despite my best efforts to extend it's useful life.

E = hν.

I rarely measured the energy of single photons directly and I rather think BC invoked hc/λ in his spectroscopy, so if anything you were probably closer to a direct measurement than either of us.

Indeed whilst I could produce a spectrum from infrared to, say, 300 ? 0.05 keV with a very precise x-ray generator, it was a continuum with a few fluorescent spikes, whilst your output was probably a pure sine wave!
