LLM Analysis

Numerator Metabolite Explanation:

Long-chain polyunsaturated fatty acid (PUFA) biosynthesis.4[1], 5[2]

Denominator Metabolite Explanation:

Glycerophospholipid metabolism; Phospholipid Metabolism.6[1], 7[2]

Ratio Explanation:

The ratio reflects FADS1/FADS2 enzymatic efficiency, comparing the long-chain PUFA product (DPA) to a phosphatidylcholine carrying precursor fatty acids (linoleic and alpha-linolenic acid).1[1], 8[2]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Genetic variation in FADS1/FADS2 alters long-chain PUFA synthesis, impacting precursors of inflammatory mediators.9[1], 10[2] This influences lipid profiles and inflammatory responses linked to hypercholesterolemia, IBD, T2D, and cardiovascular phenotypes.11[3], 12[4]

Phenotype Driver:

Gene-centric:FADS1/FADS2
