LLM Analysis

Numerator Metabolite Explanation:

Sphingolipid metabolism, ceramide de novo synthesis.4[1], 5[2]

Denominator Metabolite Explanation:

Glycerophospholipid metabolism, fatty acid biosynthesis.6[1], 7[2]

Ratio Explanation:

This ratio reflects the balance between sphingolipid and glycerophospholipid pools, influenced by FADS1 activity on polyunsaturated fatty acids that constitute the denominator metabolite.1[1], 3[2]

Ratio Evidence:

metabolites related through biology

Gene Ratio Phenotype Relationship:

Genetic variation in FADS1 alters polyunsaturated fatty acid metabolism, impacting the sphingomyelin to phosphatidylcholine ratio.8[1], 9[2] This dyslipidemia is linked to inflammatory states and increased risk for cardiovascular diseases like valvular heart disease and phlebitis, and hypercholesterolemia.10[3], 11[4], 12[5]

Phenotype Driver:

Gene-centric:FADS1
