lipase activity
Definition
Target type: molecularfunction
Catalysis of the hydrolysis of a lipid or phospholipid. [GOC:mah, ISBN:0198506732]
Lipase activity refers to the enzymatic hydrolysis of ester bonds in triglycerides, which are the main constituents of fats and oils. This process involves the breakdown of triglycerides into glycerol and free fatty acids. Lipases are crucial for the digestion and absorption of dietary fats, playing a vital role in energy metabolism. They catalyze the reaction by binding to the triglyceride substrate and facilitating the addition of a water molecule across the ester bond. This results in the cleavage of the bond and the release of fatty acids and glycerol. The activity of lipases can be influenced by various factors such as pH, temperature, and the presence of inhibitors. Lipases are found in a wide range of organisms, including animals, plants, and microorganisms, and they have diverse applications in various industries, including food processing, pharmaceuticals, and bioremediation.'

| rifampin | Rifampin: A semisynthetic antibiotic produced from Streptomyces mediterranei. It has a broad antibacterial spectrum, including activity against several forms of Mycobacterium. In susceptible organisms it inhibits DNA-dependent RNA polymerase activity by forming a stable complex with the enzyme. It thus suppresses the initiation of RNA synthesis. Rifampin is bactericidal, and acts on both intracellular and extracellular organisms.
