LLM Analysis

Numerator Metabolite Explanation:

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

Denominator Metabolite Explanation:

Diacylglycerol synthesis, Glycerophospholipid metabolism.5[1], 6[2]

Ratio Explanation:

The ratio of a phosphatidylcholine to a diacylglycerol containing different fatty acids likely reflects FADS1/FADS2 activity in converting linoleic acid (18:2) to arachidonic acid (20:4).

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

FADS1/FADS2 variants influence desaturase activity, altering the balance of omega-6 fatty acids (linoleic vs. arachidonic acid), which is reflected in the metabolite ratio. This altered lipid profile is associated with hypercholesterolemia and inflammatory conditions like IBD and asthma.7[1], 8[2], 9[3], 10[4], 11[5]

Phenotype Driver:

Gene-centric:FADS1/FADS2
