NER Named-entity recognition gpt-5-mini
Instruction
Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).
Input

Target entity: Preiss–Handler pathway
Context triple: [NAD+, isBiosynthesizedVia, Preiss–Handler pathway]
  • A. Leloir pathway of galactose metabolism
    The Leloir pathway of galactose metabolism is the primary biochemical route by which cells convert galactose into glucose-1-phosphate for entry into central energy and biosynthetic pathways.
  • B. Calvin cycle
    The Calvin cycle is the series of biochemical reactions in photosynthetic organisms that use carbon dioxide and energy-rich molecules (ATP and NADPH) to synthesize organic sugars.
  • C. Warburg effect
    The Warburg effect is a phenomenon in which cancer cells preferentially produce energy through high-rate glycolysis followed by lactic acid fermentation, even in the presence of sufficient oxygen.
  • D. Sharpless aminohydroxylation
    Sharpless aminohydroxylation is a stereoselective chemical reaction that converts alkenes into vicinal amino alcohols using a chiral catalyst, widely used in asymmetric synthesis.
  • E. DAGL enzyme
    The DAGL enzyme is a key biosynthetic enzyme in the endocannabinoid system that produces the signaling lipid 2-arachidonoylglycerol (2-AG) from diacylglycerol.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
