    I never knew that estrogen and testosterone are so similar. I also didn’t know that there is not one estrogen molecule, but that estrogens are a molecule class.

    Thanks, OP!

      I think it’s saying that estrogen has more double carbon bonds, so it’s more stable as a molecule

        It has basically an entire benzene ring, one of the most stable structures in chemistry.

        That’s an overstatement, but it is extremely stable compared to most things in solution.

          It’s been a while since I took organic chemistry, but isn’t that literally just a benzene ring?

            Meh, it’s a benzene ring but with the hydroxyl and other groups on, it is a diminished benzene ring, the inter-ring bonds aren’t quite as stable as a pure aromatic ring.

            Has to do with the electron bonds having slightly longer lengths than in their 1.5 configuration. The difference is prety minor.

        Not quite. The other person is right about the benzene ring, but also testosterone has a non-aromatic double bond, making it less stable because in organic compounds double bonds are more reactive than single bonds.

      In organic chemistry, there’s a concept called delocalized pi orbitals. The exact reason why it works is complicated and outside the scope of organic chemistry, so I’m not sure if I can really explain it anyways. But the takeaway is that when you see a double bond, single bond, double bond pattern, that generally indicates that the bonds are actually being shared across the entire motif. ie, it’s not really a double bond, it’s more like… a 1.5-bond.

      Having the bonds be shared across multiple atoms gives that region of the molecule special properties, the primary of which is that it tends to be really stable. The reason for that is that any disruption toward that region (eg, adding an electron) gets distributed across the motif, so that each atom is only minorly disturbed.

      And the bigger the motif is, the more stable the region is because it’s able to distribute disturbances better.

      Benzene (the hexagon motif circled) is made exclusively of this double bond, single bond, double bond motif. And as a result, it’s well known for being extremely difficult to modify or destroy. You really have to jump through hoops to do any sort of organic chemistry with benzenes. The motif circled in testosterone still has delocalized pi orbitals, but it’s not as extensive as a benzene, and so it’s less stable

      Oh man, the lower half of this image was everywhere ten odd years ago. Or maybe longer. Shit.

      It’s just “Oooooh, burn!” in a sarcastically distant tone. Almost like it’s a daily occurrence.

      I never quite liked it even if it looks very fake. The particular stab at humor it went for didn’t really do it for me.

    Cold water is the opposite of what you want to put on a burn. Blisters are a reaction to the rapid change in temperature not the heat.

        Depending on the severity and type of the burn, and the amount of time that has passed (ideally none), actually yes you would.

            Most reputable sources will specifically say “not cold”. Both first aid trainings I have taken have outlined specific cases where starting with warm and then moving slowly to cool water will help prevent blisters.

            YMMV.

              Ah okay, yeah using warm water (near human body temperature) makes sense to me. The person you replied to said hot water so I assumed you were talking about that.

              They specify cool as the appropriate temperature. They don’t want people putting ice water on burns. The water is mostly to clean the wound and for pain management, as cooling the burns eases the pain temporarily.

              I’ve never heard of treating a burn with warm water, that would be painful.

    This is next level because only Charles Murray stans could be persuaded that molecular bonds imply emotional strength.
