What it is

The omega-6 fat immediately before arachidonic acid in the conversion chain, also called dihomo-gamma-linolenic acid.

Why it matters

The step from here to arachidonic acid is the one that varies most between people, so the pair together says more than either alone.

Reading the number

A high value with a low arachidonic acid suggests the conversion is running slowly. It also tends to rise with insulin resistance, independently of what you eat.
