Sentient Marmite: The Truth may make you fret.
I'd say it interests biologists.All the amino acids in living creatures are left-handed, which is the bit that interests astrophysics: why did Earth end up with those molecules and not others?
The wrong handed sugars (only exist synthetically) have no sweetness as the molecules are the wrong shape. Sugar solution affects polarised light, the other handedness affects it in the opposite direction (See Kerr cells, an early technology for projection TV in 1950s and modulating lasers in late 1960s / early 1970s, which have been made with sugar)
So starlight passing through a cloud can reveal chirality of organic molecules. The right-handed form has been found for the first time.
Astroboffins' discovery gives search for early life a left hand. Or right
There are at least two mistakes in the article.
1) It's not a molecule used in biological processes, but it is an organic chemistry molecule
2) Different chirality (Left handed or right handed version) almost always affects polarised light differently.
