LLM Analysis

Numerator Metabolite Explanation:

Glycerophosphoinositol metabolism

Denominator Metabolite Explanation:

Glycerolipid metabolism

Ratio Explanation:

The ratio reflects FADS desaturase activity, where a lower ratio suggests more efficient conversion of linoleoyl precursors to arachidonoyl products.1[1], 2[2], 5[3], 6[4]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Reduced FADS1/FADS2 activity, indicated by a higher ratio, alters polyunsaturated fatty acid levels, impacting lipid profiles and inflammatory responses, which are linked to phenotypes like dyslipidemia and cholelithiasis.7[1], 8[2], 9[3], 10[4], 11[5]

Phenotype Driver:

Gene-centric:FADS1/FADS2
