LLM Analysis

Numerator Metabolite Explanation:

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

Denominator Metabolite Explanation:

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

Ratio Explanation:

This ratio compares sphingomyelins with shorter to medium fatty acid chains (C15-C17) against those with very-long-chain fatty acids (C21-C23), likely reflecting CERS4's influence on the ceramide substrate pool.5[1], 1[2], 2[3]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

No associated phenotype was provided, so a causal link cannot be established.

Phenotype Driver:

none
