LLM Analysis

Numerator Metabolite Explanation:

Omega-6 fatty acid biosynthesis.3[1]

Denominator Metabolite Explanation:

Fatty acid metabolism/biosynthesis.4[1], 5[2]

Ratio Explanation:

The ratio reflects FADS2 enzymatic activity converting precursors into docosapentaenoate (n6 dpa) relative to the pool of the less common fatty acid 10-heptadecenoate.

Ratio Evidence:

metabolites not in a pathway but enzyme catalyzes one metabolite

Gene Ratio Phenotype Relationship:

Genetic variants in FADS2 influence its enzymatic activity, altering the production of long-chain polyunsaturated fatty acids like docosapentaenoate (n6 dpa).2[1] This dysregulation of lipid metabolism is associated with an increased risk for hypercholesterolemia, cholelithiasis, type 2 diabetes, and certain skin neoplasms.6[2], 7[3]

Phenotype Driver:

Gene-centric:FADS2
