Think step by step, and your final answer **must** be returned in the format: <answer> ... </answer>. For example:
<answer>The molecule is an epoxy(hydroxy)icosatrienoate that is the conjugate base of 11-hydroxy-(14R,15S)-epoxy-(5Z,8Z,12E)-icosatrienoic acid, obtained by deprotonation of the carboxy group; major species at pH 7.3. It is a conjugate base of an 11-hydroxy-(14R,15S)-epoxy-(5Z,8Z,12E)-icosatrienoic acid.</answer>

[O][=C][Branch1][C][O][C][N][C][=Branch1][C][=O][C][=C][C][=C][O][Ring1][Branch1]

The molecule is a glycine derivative that is the carboxamide obtained by the formal condensation of the amino group of glycine with 2-furoic acid. It has a role as a human metabolite. It is a N-acylglycine and a member of furans. It derives from a 2-furoic acid. It is a conjugate acid of a N-(2-furoyl)glycinate.

SMILES: O=C(O)CNC(=O)c1ccco1
