Fatty acid is a building block for a wide variety of different products—from lubricants to foods. enzyme that is made in the pancreas and digest FAT. There are some advantages in using enzymes in organic media as opposed to aqueous media, including: 1) shifting thermodynamic equilibrium to favor synthesis over hydrolysis, 2) reduction of water-dependent side reactions, Functional lipids, primarily derived through the modification of natural lipids by various processes, are widely acknowledged for their potential to impart health benefits. They are secreted from various organs, e. The digestive system - AQA Synergy Digestive enzymes. They hydrolyze triglycerides (fats) into their component For fragile oils like castor oil or highly unsaturated oils, the thermal fat splitting process cause so high formation of by-products that alternative processes are desired. One approach to achieve a switch-like control over enzyme activity is to design a split enzyme, where the protein is separated into two polypeptides with each inactive fragment fused to inducible dimerization domains. Fat splitting using enzyme is important in reducing the fat content of human body. 5) mucosal folds. Mastication.
