Which pancreatic enzyme primarily digests fats?

Explanation:
Pancreatic lipase is the primary enzyme that digests fats. In the small intestine, fats are first emulsified by bile salts, which increases the surface area for enzymes to act. Pancreatic lipase then hydrolyzes triglycerides into fatty acids and monoglycerides, which are small enough to be absorbed by enterocytes. This process is why fats are efficiently digested in the presence of bile and pancreatic enzymes. Amylase digests carbohydrates, not fats. Trypsin digests proteins by cleaving peptide bonds. Secretin is a hormone that stimulates the pancreas to release bicarbonate-rich fluid, aiding digestion but not breaking down fats.
