N-terminal metabolites of [Pyr1]apelin-13 identified from human plasma. (A) sequence of [Pyr1]apelin-13 N-terminal fragments identified, (B) relative abundance of N-terminal metabolites (n = 6, data represent mean ± SD). Star on the [Pyr1]apelin-13 residues indicate amino acid residues critical for receptor binding.
