Dec 3, 2017 at 5:46 | comment | added | BobRodes | @Draco18s I recall that a study was done back in the 70s where saccharin caused cancer in rats. The general understanding among us teenagers (so perhaps an inaccurate understanding, because, well, teenagers) was that people would have to drink a bathtub full of the stuff every day for quite a while to get as much saccharin as they used in the rats. | |
Dec 3, 2017 at 5:09 | comment | added | Draco18s no longer trusts SE | @BobRodes That's the sugar one, yes. Still can't remember the drug that caused issues (was back in like the 50s or 60s before the handedness of proteins was well understood). I see a topic about it every couple of years and can never remember what it was (and today...I was unable to Google Fu either one; kept finding Tagatose being listed as a mirror molecule). | |
Dec 3, 2017 at 4:15 | comment | added | BobRodes | @Draco18s That's aspartame, commonly sold as Equal. I remember when it first came out. The mirror molecule was a big selling point as they were bringing it to market. It was certainly an improvement on saccharin, which was at the time the only available artificial sweetener. | |
Dec 2, 2017 at 22:34 | comment | added | Draco18s no longer trusts SE | Mirror Milk! I've lost track of it now, but there was a drug that caused cancer/birth defects because a good portion of the active molecule was right-handed due to the manufacturing process (all life on Earth uses left-handed--chiral--proteins). That said, mirror milk is not always dangerous. There's at least one common sugar substitute that is a mirror molecule: it activates the same receptors in our tongue, but can't be digested. | |
