Triglycerides undergo rapid enzymatic hydrolysis when exposed to specific enzymes called_________________?
Show answer Hide answer
Answer: C. Lipases
Explanation
Triglycerides consist of three fatty acid molecules esterified to a glycerol backbone. Enzymes that specifically catalyze the hydrolysis of ester bonds in lipids are called lipases. These specialized biocatalysts rapidly break down dietary fats into glycerol and fatty acids. Lipases belong to the broader class of hydrolase enzymes found in digestive systems. Pancreatic lipase operates efficiently in the small intestine aided by bile salt emulsification. Optimal catalytic activity requires specific physiological pH and temperature ranges for each lipase.
Human digestion relies on lipases to process dietary fats into absorbable cellular nutrients. Biotechnology industries utilize microbial lipases to manufacture detergents and biodiesel fuels. Clinical blood tests measure lipase levels to diagnose acute pancreatitis and digestive disorders. Lyases catalyze the breaking of various chemical bonds by means other than hydrolysis or oxidation. Ligases catalyze the joining of two large molecules by forming new chemical covalent bonds. Hydrolases is the broader enzyme class, whereas lipases specifically target lipid triglycerides.
