  1. Sugars are essential #biomolecules, serving as metabolic fuels, nucleic acid backbone components and structural or energy-storage polymers.

    A central question in origin-of-life research is how monosaccharides formed on the primitive Earth, as laboratory experiments under #prebiotic conditions yield insufficient concentrations.

    The detection of #ribose, #glucose and other monosaccharides in #asteroids and #meteorites suggests an exogenous origin, possibly in the interstellar medium (ISM) before meteoritic parent-body formation.

    However, no #sugar has been observed in the ISM so far.

    Now astronomers report the discovery of #erythrulose, a chiral four-carbon ketose, in the ISM.

    Erythrulose appears to be at least eight times more abundant than analogous three-carbon sugars, which remain undetected in our ultrasensitive observations.

    Quantum chemical and astrochemical models indicate that erythrulose forms efficiently on interstellar dust grains from simpler two-carbon aldehydes and alcohols.

    As ketoses readily isomerize into aldoses in aqueous conditions, interstellar erythrulose could have contributed to the sugar inventory available for early metabolic and replication processes.

  6. I don't get it. Left and right I'm reading about magic ingredients that help people stabilize their blood sugar. How about not pumping it up to begin with? Then you won't need magic to control it.

    Q: What's the (total) amount of glucose you have in your blood at any time, given a healthy level? Rule of thumb: Don't eat more than that in 1 sitting of carbs.

  8. If we meet: pick up a mnemonic to hand over to someone else who can make good use of it (format: business card)

    If we don't meet: just tell them. Works without paper mnemonic as well.

    (Card is german, but the site is 97% bilingual)

  14. A mouse study finds that fructose and glucose affect different signaling pathways from the gut to the brain, and caloric equivalents result in less activation of receptor neurons in the brain by fructose than by glucose. This did not affect food intake, however, evidently because fructose increases intestinal water content and feelings of satiety.

  16. Most diabetes apps either track everything and overwhelm you or nothing in between.
    Glu Sight connects your daily glucose readings to an estimated A1C, so you can see the longer-term picture alongside your day-to-day numbers.
