LLM Analysis

Numerator Metabolite Explanation:

Glycerophospholipid metabolism, PUFA biosynthesis.3[1]

Denominator Metabolite Explanation:

Glycerophospholipid metabolism, Fatty acid metabolism.4[1]

Ratio Explanation:

The ratio reflects the activity of FADS1/FADS2, indicating the conversion rate of precursor fatty acids (related to the denominator) to arachidonic acid (in the numerator).2[1], 5[2]

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

FADS1/FADS2 gene variants alter enzyme activity, impacting the balance of pro-inflammatory (e.g., arachidonic acid) and anti-inflammatory fatty acids.6[1], 5[2] This dysregulation affects lipid profiles (hypercholesterolemia) and inflammatory responses, contributing to inflammatory bowel disease, asthma, and cardiovascular conditions.7[3], 8[4], 9[5]

Phenotype Driver:

Gene-centric:FADS1/FADS2
