Triglycerides are resynthesized in smooth endoplasmic reticulum-monoglycerides and free fatty acids are resynthesized into triglycerides through two different enzymatic pathways both of which are associated mainly with smooth er. chylomicrons are composed in the rough er and golgi. fatty-acid binding proteins appear to preferentally bind fatty acids of different lengths, but these are important after absorption has taken place and before esterification occurs, but have no role in intracellular transport. the major triglyceride (tg) resynthesis pathway involves synthesis of tgs from 2-monolycerides and coenzyme a - activated fatty acids. glycerol is formed by pancreatic lipase - dependent conversion of triglycerides to monoglycerides, and free fatty acids and glycerol. the glycerol enters and exits the enterocyte by passive diffusion.
