What Wikipedia says

Isovaline is a rare amino acid found in the Murchison meteorite, which landed in Australia in 1969. The discovery of isovaline in the biosphere demonstrates an extraterrestrial origin of amino acids and has been linked to the homochirality of life on Earth, suggesting a role in the origin of life.
