You are a professional chemist. Your task is to generate a natural, concise, and chemically accurate description of a given molecule.

Please provide a step-by-step analysis explaining how you interpret the molecular structure, identify key features and functional groups, and summarize it into a clear and informative description.

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>
