Task: Please create a text description for a molecule.
Molecule SMILES: C[C@H](O)C#CC#CC#CC#CCCCCCCCC(=O)O
Constraint: Answer the question with complete sentences.
Result: The molecule is a straight-chain, C18 polyunsaturated fatty acid having four conjugated C#C bonds at positions 9, 11, 13 and 15 as well as an (S)-hydroxy group at position 17. It has a role as an antimalarial, an antineoplastic agent and an antiviral agent. It is a tetrayne, a long-chain fatty acid, an acetylenic fatty acid, a straight-chain fatty acid and a hydroxy polyunsaturated fatty acid.
