LLM Analysis

Numerator Metabolite Explanation:

Glycerophospholipid metabolism.4[1], 5[2]

Denominator Metabolite Explanation:

Glycerophospholipid metabolism.4[1], 5[2], 6[3]

Ratio Explanation:

The ratio of 1-stearoyl-gpe (18:0) to 1-linoleoyl-gpe (18:2) reflects fatty acid desaturase activity, where FADS enzymes likely mediate the conversion of the stearoyl to the linoleoyl moiety.

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Genetic variants in the FADS gene cluster influence desaturase activity, altering the ratio of saturated to polyunsaturated lysophosphatidylethanolamines.7[1], 8[2], 9[3] This altered lipid profile is associated with hypercholesterolemia and may contribute to the formation of follicular cysts.10[4], 11[5]

Phenotype Driver:

Gene-centric:FADS1/FADS2
