Amino Acids 71-86 gonadotropin releasing hormone 1 Homo sapiens 43-47 25404067-8 2014 This can explain why substitutions of L-amino acids for Gly 6 are known to inactivate GnRH while D-amino acid substitutions enhance its activity. Amino Acids 38-51 gonadotropin releasing hormone 1 Homo sapiens 86-90
