DescriptionCinnamoylglycine 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. Cinnamoylglycine is an extremely weak basic (essentially neutral) compound (based on its pKa). Robustaside A is found in Breynia officinalis, Breynia vitis-idaea, Grevillea robusta, Grevillea robusta A.Cunn, Vaccinium arctostaphylos and Viburnum wrightii. It was first documented in 2000 (PMID: 10656423). An N-acylglycine in which the acyl group is specified as (2E)-3-phenylprop-2-enoyl (cinnamoyl) (PMID: 34748561) (PMID: 34746809) (PMID: 34740265) (PMID: 34728144).
