Beaded Serotonin

In the midst of preparing for the Bead & Button Show, and after a fabulous time teaching at the San Diego Bead Society this weekend, I carved out a little time to make some more beaded molecules.

Serotonin

Serotonin is a small molecule that contributes to feelings of happiness and well-being. It's made from the amino acid tryptophan, and it functions as a neurotransmitter; a molecule that carries messages from one neuron to another in the nervous system. Serotonin is found in both the gut, where it regulates intestinal functions, and the brain, where it helps to regulate mood, appetite, and sleep. It's a huge target of antidepressant drugs, which aim to increase serotonin levels.

From an organic chemist's point of view, serotonin is about the same size as caffeine, and its two rings (the indole functional group) are also flat. It has comparatively more carbon atoms with only two nitrogen atoms and one oxygen atom. So, from the beader's point of view, when serotonin is woven using the same technique that I describe in my Morning Coffee Molecules pattern, the two colors of the background beads and the carbon atoms will dominate, with the colors of the nitrogen and oxygen atoms serving as accents.

Color Attempt #1

For my first attempt at a beaded serotonin molecule, I chose colors that I like because those colors make me happy. So I started with matte purple beads for the carbon atoms on a dark purple beaded background, with red luster beads for the nitrogen atoms and gold for the oxygen atom.


The result ended up much darker than I had anticipated. It's an interesting color scheme, but it doesn't scream "happy" the way that I had wanted it to.

Color Attempt #2

For my second attempt, I switched to lighter purple beads for the background, bright pink for the carbon atoms and orange for the nitrogen atoms.


It's a much happier molecule, but I wasn't as satisfied with the interplay between the pink and purple beads, as these beads are too close in value and tend to blend into each other. Plus, for this molecule to be truly happy, it needs to sit on a bed of bright and sunny background beads.

Third Time's a Charm!

For my final attempt, I put the gold beads in the background, and switched to shiny Duracoat seed beads for the individual atoms; pink for the carbon, purple for the nitrogen, and peach for the oxygen atom.


It's by far my favorite of the three, and I'll definitely be working with this color scheme again!

Next time, I'll have to try beaded dopamine.
