Time courses of changes in fatty acids content of AH, SH and VH. As shown in (a), the synthesis of ARA undergoes a series of elongation and desaturation process from palmitic acid (C16:0, PA), leading to the sequential production of stearic acid (C18:0, SA), oleic acid (C18:1, OA), linoleic acid (C18:2, LA), γ-linolenic acid (C18:3, GLA), dihomo-γ-linolenic acid (C20:3, DGLA) and arachidonic acid (C20:4, ARA). (b) The changes of lipid content and major fatty acids content (c-i) in dried cell weight (n = 3).
