LLM Analysis

Numerator Metabolite Explanation:

Polyunsaturated fatty acid synthesis3[1]

Denominator Metabolite Explanation:

Fatty acid biosynthesis4[1], 5[2]

Ratio Explanation:

The ratio of adrenate (22:4n6) to stearate (18:0) reflects fatty acid desaturase (FADS) enzyme activity, converting saturated to polyunsaturated fats.6[1], 7[2]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Altered FADS1/FADS2 activity, indicated by the adrenate/stearate ratio, affects polyunsaturated fatty acid levels.8[1], 2[2] This dysregulation is linked to inflammatory conditions and has been associated with follicular cysts, potentially through disrupted linoleic acid metabolism.9[3]

Phenotype Driver:

Gene-centric:FADS1/FADS2
