basic FUNCTION	converting free long-chain fatty acids into fatty acyl-CoA esters
	playing a role in lipid biosynthesis and fatty acid degradation
	utilizing preferentially arachidonate and eicosapentaenoate as substrat
	might play a role in the growth of hepatic cancer cells
	involved in learning and memory
	its expression controls both lipooxygenase and cyclooxygenase metabolism of arachidonic acid
	modulates PGE&
	8322; release from human smooth muscle cells and may regulate a number of processes dependent on the release of arachidonic acid-derived lipid mediators in the arterial wall
	plays crucial roles in physiological functions such as steroid synthesis and in pathological processes such as tumorigenesis
	specifically expressed in brain and playing an important role in arachidonate metabolism and neuronal differentiation in the brain
	might play a key role in brain function, especially neuronal cells
	might play an important role during neuronal differentiation at the early phase
	key enzyme in steroidogenesis
	phosphoprotein whose phosphorylation is hormone-dependent
	acts as a dimer and phosphorylation occurs after dimer formation
	is involved in several cellular functions including steroidogenesis, synaptic development and cancer metastasis
	is required for ferroptotic cancer cell death, and is not only a sensitive monitor of ferroptosis, but also an important contributor of ferroptosis
	ACSL4 is an essential component for ferroptosis execution
	involvement of ACSL4 and ACSL3 in insulin secretion
