Transfer of sterical hindrance from the periphery to the center of biliverdins by placing a methyl group at N23 and hydrogens at the beta-carbons in position 12 and 13 changes the conformation of the chromophore from (10syn, 4syn) to (10anti,14anti). Additional reduction of sterical hindrance by placing a further hydrogen at the beta-carbon in position 8 induces a change in configuration from (9Z) to (9E).
