LLM Analysis

Numerator Metabolite Explanation:

Glycerolipid metabolism, fatty acid biosynthesis.4[1], 5[2]

Denominator Metabolite Explanation:

Glycerolipid metabolism, PUFA metabolism.6[1], 7[2]

Ratio Explanation:

This ratio reflects FADS desaturase activity, contrasting a diacylglycerol with its precursor fatty acids against one containing the FADS-derived product, arachidonic acid.

Ratio Evidence:

reaction where the ratio is shared through a pathway

Gene Ratio Phenotype Relationship:

Genetic variation in FADS1/FADS2 alters polyunsaturated fatty acid synthesis, reflected in the diacylglycerol ratio.8[1], 9[2], 10[3] This metabolic dysregulation is causally linked to pure hypercholesterolaemia and inflammatory conditions like asthma and inflammatory bowel disease, which share genetic risk factors.11[4], 12[5], 13[6], 14[7]

Phenotype Driver:

Gene-centric:FADS1/FADS2
