LLM Analysis

Numerator Metabolite Explanation:

Glycerophospholipid metabolism

Denominator Metabolite Explanation:

Glycerophospholipid metabolism

Ratio Explanation:

The ratio of 1-stearoyl-gpc (18:0) to 1-linoleoyl-gpc (18:2) reflects the balance between saturated and polyunsaturated fatty acids, influenced by FADS1/FADS2 desaturase activity.1[1], 4[2], 5[3]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Reduced FADS1/FADS2 activity is associated with higher levels of precursor fatty acids like linoleic acid (18:2) and lower levels of products, impacting inflammatory pathways and lipid profiles, which are linked to cholelithiasis and cardiovascular disease risk.6[1], 1[2], 4[3], 7[4], 8[5]

Phenotype Driver:

Gene-centric:FADS1/FADS2
