Isoserine is an α-Hydroxy-β-amino acid, and an isomer of serine.  The first documented synthesis of isoserine in a laboratory setting was by Miyazawa et al., who published their results in 1976. See also  Miller–Urey experiment 
Isoserine is a non-proteinogenic α-Hydroxy-β-amino acid, and an isomer of serine. Non-proteinogenic amino acids do not form proteins, and are not part of the genetic code of any known organism. Isoserine and other non-proteinogenic amino acids have only been produced synthetically.
