## Step 1<br />De novo fatty acid biosynthesis is a process that involves the creation of fatty acids from simpler molecules. This process is essential for the production of fats and oils in plants and animals.<br /><br />## Step 2<br />The precursor for this process is Acetyl CoA, which is a molecule that plays a central role in metabolism. Acetyl CoA is synthesized from carbohydrates, fats, and proteins.<br /><br />## Step 3<br />The synthesis of Acetyl CoA can occur through several pathways. These include glycolysis, the citric acid cycle, and the breakdown of amino acids.<br /><br />## Step 4<br />Once Acetyl CoA is synthesized, it can be used to create fatty acids. This process addition-carbon units to Acetyl CoA, which are derived from malonyl CoA.<br /><br />## Step 5<br />The fatty acids that are synthesized can then be used to create triacylglycerol and phospholipids, which are essential components of cell membranes.<br /><br />## Step 6<br />Cholesterol, another important molecule, is also synthesized from Acetyl CoA. This process involves a series of complex reactions that convert Acetyl CoA into cholesterol.
