Purple stem experiences....?

I dont believe this unfortunatly, purple anthocyanin is a unison of sugar/glucose and cyanidin which produces purple anthocyanin. It is more related to the over abundance of sugar caused by lack of transportation. We might cite nutrient values or environmental stresses as a cause.

These are not areas i like.
I do not think you can correlate cyanin fraction with the amount of sugar in the plant. Enzymes mediate the reaction, and the control on them isn't quantity of starting material (like sugars) but hormonal enzyme up-and downregulation.

Cyanins and their cyanidin aglycones (non-sugar portions) are variable in color. This chart is in German but should illustrate structure v. color.
Flavylium cation form = red, pH below 3
(benzo)quinoid form not hydrated, purple
Ionic form not hydrated, dark blue
(naphtho)quinoid form dianion - blue-green
hydrated chromenone - colorless
Chalcone (benzalacetophenone) form, yellow at pH >11


Which would support what I am saying: That cyanidin is not colorless. And if I'm right about that, I'm pretty sure I'm right about the rest.

It's not so simple. Cyanidins and their cyanine glycosides span the rainbow and also have colorless-to-pale-yellow forms. Depending on pH and where the sugar portion attaches ... the color can be very different in the same compound(s).

But they aren't colorless, am I correct? And Cyanidin is a derivative within the class of anthocyanin, specifically the cyanidin attached to glucose being present in plants, am I right? Like I said, feel free to light me up if I'm wrong.

Cyanidin is made from a colourless precurssor, theres a lot of chem involved in its colour.
Cyanidin is a pigment. A fucking pigment. How the fuck can it be colorless? Maybe the "precursor" is colorless, but not cyanidin itself, which is what you've been saying all along.

They are typically colored, but not reliably.
Anthocyanins are a subset of cyanins.

Cyanins are cyanidins with attached sugar portions. These are "mostly" glucose, and I don't know what other simple sugars might be involved.

Here's one of those people we were discussing earlier. If you don't mind, help me sort out with him the misconception in his belief, and if it is me who is under the wrong impression, light me up.
This is above my pay grade. But I am very flattered you think well of me. I think @Singlemalt will be the definitive source. Let's see what he says.
Dude no ones supressing cyanidins, anthocyanins on the other hand ...

Whats funny is you just summoned a load of mods as your flaming me, good luck with that and those anthocyanins, or is it cyanidins that are giving you that purole stem :-)
Nah, we aren't mods and yes frustration can occur. But it seems to me the two of you are talking at cross purposes which can be very frustrating. Let's wait for SM to help. If he doesn't know then you both need to set up plants and start experimenting. LOL Welcome to science :D

Are cyanidins a subset of anthocyanins? Are they colored? Would it be beneficial to find a way to eliminate them or should they be left alone?
