De novo synthesis

De novo synthesis is a process where complex molecules are synthesized from simple starting materials that are unrelated in structure to the final product. It involves constructing these materials completely from scratch. For instance, in the context of de novo lipogenesis, the body can start with molecules such as sugars and convert them through multiple enzymatic steps into fats. This transformation involves intermediate stages where the compounds do not resemble the initial substances nor the final fat molecules 1.
