LLM Analysis

Numerator Metabolite Explanation:

Sphingolipid biosynthesis.5[1], 6[2], 7[3]

Denominator Metabolite Explanation:

Sphingolipid biosynthesis.5[1], 6[2], 7[3]

Ratio Explanation:

This ratio reflects the substrate specificity of CERS4, comparing the production of sphingomyelins with C21-C23 fatty acids to those with C18-C19 fatty acids.1[1], 8[2]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

No phenotype was provided; therefore, a causal link between CERS4, the sphingomyelin ratio, and a phenotype cannot be established.

Phenotype Driver:

none
