<P> Fatty acid synthesis is the creation of fatty acids from acetyl - CoA and NADPH through the action of enzymes called fatty acid synthases . This process takes place in the cytoplasm of the cell . Most of the acetyl - CoA which is converted into fatty acids is derived from carbohydrates via the glycolytic pathway . The glycolytic pathway also provides the glycerol with which three fatty acids can combine ( by means of ester bonds ) to form triglycerides ( also known as `` triacylglycerols '' , to distinguish them from fatty `` acids '' - or simply as `` fat '' ) , the final product of the lipogenic process . When only two fatty acids combine with glycerol and the third alcohol group is phosphorylated with a group such as phosphatidylcholine , a phospholipid is formed . Phospholipids form the bulk of the lipid bilayers that make up cell membranes and surround the organelles within the cells ( e.g. the cell nucleus , mitochondria , endoplasmic reticulum , Golgi apparatus etc . ) </P>
