(2E)-Octadecenoyl-CoA + Hydrogen Ion + NADPH → NADP + Stearoyl-CoA
L-Serine + Palmitoyl-CoA → 3-Dehydrosphinganine + Carbon dioxide
Hydrogen Ion + Malonyl-CoA + Palmitoyl-CoA → 3-oxooctadecanoyl-CoA + Carbon dioxide + Coenzyme A
Adenosine triphosphate + Coenzyme A + Palmitic acid → Adenosine monophosphate + Palmitoyl-CoA + Pyrophosphate
3-oxooctadecanoyl-CoA + Hydrogen Ion + NADPH → (3R)-3-hydroxy-stearoyl-CoA + NADP
(3R)-3-hydroxy-stearoyl-CoA → (2E)-Octadecenoyl-CoA + Water
Biosynthesis of Unsaturated Fatty Acids (Stearoyl-CoA)
Peroxisomal hydratase-dehydrogenase-epimerase
3-oxoacyl-[acyl-carrier-protein] reductase
Very long-chain fatty acid transport protein
2 Hydrogen Ion + Oxygen + Sphinganine + ferrocytochrome b5 → Phytosphingosine + Water + ferricytochrome b5
3-Dehydrosphinganine + Hydrogen Ion + NADPH → NADP + Sphinganine
Phytosphingosine + Stearoyl-CoA → Coenzyme A + Hydrogen Ion + N-stearoylphytosphingosine
