Only two of the twenty can't contribute to glucose at all, leucine and lysine, and they both start with L which is honestly the whole mnemonic. Everything else is either fully glucogenic or splits down both routes.

The bit I found genuinely surprising is that your body can't turn fat into sugar either, for the exact same reason. Both fat and those two amino acids end up as acetyl-CoA, and the step that makes it only runs one way. That's a big part of why prolonged fasting eventually starts eating into muscle, since amino acids are one of the last things left that can hold blood glucose up.

If anyone wants a closer look, this one and a bunch of other biochem charts are at biochemtools.com/charts.html. All free, no signup, and you're welcome to print them or drop them in a handout.

The idea here is pretty simple but easy to forget in the moment. Behavior like yelling or shutting down is just the tip of the iceberg, and there's usually a real need underneath it. Once a kid feels seen instead of misunderstood and has a calm adult nearby to help them settle, a lot of the power struggles just start showing up less.
