LLM Analysis

Numerator Metabolite Explanation:

Sphingolipid metabolism.5[1], 6[2]

Denominator Metabolite Explanation:

GPI anchor biosynthesis.7[1], 8[2]

Ratio Explanation:

The ratio reflects the balance between two major membrane lipid classes, likely modulated by FADS-dependent availability of shared polyunsaturated fatty acid precursors.

Ratio Evidence:

metabolites related through biology

Gene Ratio Phenotype Relationship:

Altered FADS1/FADS2 activity dysregulates PUFA metabolism, impacting membrane lipid composition.3[1], 9[2] This shift is linked to changes in lipoprotein metabolism and inflammatory responses, contributing to phenotypes like hypercholesterolemia, type 2 diabetes, and inflammatory bowel disease.1[3], 2[4], 10[5], 11[6]

Phenotype Driver:

Gene-centric:FADS1/FADS2
