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>

The molecule is a branched amino oligosaccharide that is an undecasaccharide derivative consisting of a linear trisaccharide of beta-D-mannose, N-acetyl-beta-D-glucosamine and N-acetyl-D-glucosamine residues all linked in sequence (1->4), to the mannosyl residue of which are linked an N-acetyl-beta-D-glucosaminyl residue [via a (1->4) linkage], an N-acetyl-beta-D-glucosaminyl-(1->2)-[N-acetyl-beta-D-glucosaminyl-(1->4)]-alpha-D-mannosyl branched trisaccharide unit [linked (1->3)], and an N-acetyl-beta-D-glucosaminyl-(1->2)-[N-acetyl-beta-D-glucosaminyl-(1->6)]-alpha-D-mannosyl branched trisaccharide unit [linked (1->6)], while to the N-acetyl-D-glucosamine residue at the reducing end is linked (1->6) an alpha-L-fucose residue. It is an amino oligosaccharide and a glucosamine oligosaccharide.
