Cell Processes part B

                                                                    Lipid Synthesis


    Lipid Synthesis takes place in two parts. First is fatty acid synthesis. This takes place in the cytoplasm and starts the synthesis by forming acetoacetyl-ACP. ACP guides the synthesis of fatty acids . acetoacetyl-ACP enters the elongation cycle for fatty acid synthesis, which results in chains of fatty acids being formed. Next, the lipid is assembled. The enzymes that help in lipid synthesis are bound to ctyoplasmic membrane. The fatty acids are transferred from  acetoacetyl-ACP to sn-glycerol 3-phosphate to form phosphatidic acid. The last step is the hydrophilic part of lipid being added.
