      Gamma-linolenic acid or GLA (systematic Name: 6Z,9Z,12Z-octadecatrienoic acid) is an unsaturated fatty acid found primarily in vegetable oils. GLA is categorized as an omega-6 fatty acid, and is an isomer of alpha-linolenic acid, which is a polyunsaturated omega-3 fatty acid, found in rapeseed canola oil, soy beans, walnuts, flax seed (linseed oil) and hemp seed. The human body produces GLA from linoleic acid (LA). This reaction is catalyzed by the enzyme delta6-desaturase (D6D). LA is consumed sufficiently in most diets, from such abundant sources as cooking oils and meats.
