| Common Name | 2-Pyrroloylglycine |
|---|
| Description | 2-Pyrroloylglycine belongs to the class of organic compounds known as n-acyl-alpha amino acids. N-acyl-alpha amino acids are compounds containing an alpha amino acid which bears an acyl group at its terminal nitrogen atom. 2-Pyrroloylglycine is an extremely weak basic (essentially neutral) compound (based on its pKa). These are organic compounds containing a glycine residue with the N-atom attached to another moiety through an N-ester bond. |
