LLM Analysis

Numerator Metabolite Explanation:

Polyunsaturated fatty acid biosynthesis.4[1], 5[2]

Denominator Metabolite Explanation:

Glycerophospholipid metabolism.6[1]

Ratio Explanation:

The ratio of adrenate to 1-linoleoyl-2-linolenoyl-gpc reflects the activity of FADS enzymes, which convert precursor fatty acids (linoleic/linolenic) into more elongated and desaturated products like adrenate.1[1], 2[2], 4[3]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Higher FADS1/FADS2 activity, indicated by an elevated ratio, alters lipid profiles and has been linked to various inflammatory and metabolic disorders, including cholelithiasis and type 2 diabetes, due to changes in membrane composition and production of signaling molecules.7[1], 8[2], 9[3]

Phenotype Driver:

Gene-centric:FADS1/FADS2
