In the liver cells, triglycerides are formed primarily in the following organelle:
Synthesis of triacylglycerols mainly takes place on the smooth endoplasmic reticulum of the liver but can also be generated in adipose cells. Regardless of the location of synthesis, the staing molecule is glycerol-3-phosphate produced in liver from glycerol stores or in adipose cells from dihydroxyacetone phosphate, the product of the fouh step of glycolysis.
