The molecule is a non-proteinogenic alpha-amino acid that is alanine in which one of the methyl hydrogens has been replaced by a 2-methylenecyclopropyl group. The phytotoxin known as hypoglycin A is a mixture of the diastereoisomers that have L configuration at the amino-bearing carbon. It is a non-proteinogenic alpha-amino acid, a member of cyclopropanes and an olefinic compound.
