Transesterification is a chemical process that is used to convert esters into other esters and to produce biodiesel. It has become increasingly important to find alternative, clean, and renewable energy sources due to concerns about environmental degradation and the limited nature of fossil fuels. Biodiesel, also known as fatty acid methyl ester (FAME), is a biodegradable and renewable energy source that is produced through transesterification. This process involves mixing triglycerides from animal fats and vegetable oils with alcohol in the presence of a catalyst, which can be homogeneous or heterogeneous. Originally, transesterification was used to separate glycerin from soap. The resulting monoalkyl esters make up biodiesel. Biodiesel can be made from raw materials such as vegetable oils, animal fats, and waste products, which often have high water and free fatty acid (FFA) content. This can affect the performance of traditional homogeneous base catalysts. There have been several catalysts developed for transesterification, but research is ongoing to find more efficient options. The aim of this review is to discuss the role of enzyme catalysts in transesterification. Even though currently enzyme-catalyzed reaction is not the first choice for biodiesel production industry, it has a big potential to become one. An important task is to design a good enzymatic reaction with low operational cost but with an optimum amount of biodiesel yield. High yield of biodiesel can be obtained by controlling the reaction conditions, manipulating different factors affecting the reaction.
