These are natural or synthetic compounds having sequences of amino and hydroxy carboxylic acid residues (usually α-amino and α-hydroxy acids) connected in a ring. The residues are commonly but not necessarily regularly alternating (4R)-4-{[(3S,6R,9S,12R,15S,18R,21R)-3-[(2S)-butan-2-yl]-5,8,11,14,17,20-hexahydroxy-6,12-bis(hydroxymethyl)-22-methyl-9,15-bis(2-methylpropyl)-2-oxo-18-(propan-2-yl)-1-oxa-4,7,10,13,16,19-hexaazacyclodocosa-4,7,10,13,16,19-hexaen-21-yl]-C-hydroxycarbonimidoyl}-4-{[(2S)-2-[(1,3-dihydroxydecylidene)amino]-1-hydroxy-4-methylpentylidene]amino}butanoic acid is a moderately acidic compound (based on its pKa).
