• tetradecanalReach from here →
  1. (10Z)-heptadecenoic acid formation
  2. (10Z)-heptadecenoic acid formation
  3. tetradecanal + NAD(+) + H2O = tetradecanoate + NADH + 2 H(+)

  Catalysed by ALDH3A2cytosol, extracellular space

• cholesteryl (9Z)-hexadecenoateReach from here →
  1. N-(9Z-octadecenoyl)-sphing-4-enine + H2O = sphing-4-enine + (9Z)-octadecenoate
  2. beta-D-glucosyl-N-(9Z-octadecenoyl)-sphing-4E-enine + cholesterol = N-(9Z-octadecenoyl)-sphing-4-enine + cholesteryl 3-beta-D-glucoside
  3. (9Z)-hexadecenoyl-CoA + cholesterol = cholesteryl (9Z)-hexadecenoate + CoA
