additional information
-
the enzyme is independently induced by oxygen, and temperature, while chilling alone is not sufficient to raise the enzyme activity. Chilling and lowered temperature cause an increase in desaturase activity, increased membrane unsaturation and subsequently fluidity, followed by phagocytosis, overview
