SMILES: C[C@H](CC(=O)O[C@H](C)CC(=O)O[C@H](C)CC(=O)O[C@H](C)CC(=O)O[C@H](C)CC(=O)O)O
Description: The molecule is a (3R)-3-hydroxybutanoic acid oligomer resulting from the formal repeated intermolecular condensation of the hydroxy and carboxy groups of (3R)-3-hydroxybutanoic acid to give a chain in which five units of the monomer are linked together by four ester bonds. It derives from a (3R)-3-{[(3R)-3-{[(3R)-3-{[(3R)-3-hydroxybutanoyl]oxy}butanoyl]oxy}butanoyl]oxy}butanoic acid. It is a conjugate acid of a (3R)-3-{[(3R)-3-{[(3R)-3-{[(3R)-3-{[(3R)-3-hydroxybutanoyl]oxy}butanoyl]oxy}butanoyl]oxy}butanoyl]oxy}butanoate.
