Question

A good source of lipase is

• A. Saliva
• B. Pancreatic juice
• C. Bile
• D. Gastric juice

Answer 1

The correct option is B Pancreatic juice

Pancreatic juice is secreted into small intestine through the hepato-pancreatic duct. It contains enzymes – trypsinogen, chymotrypsinogen, procarboxypeptidases, amylases, lipases and nucleases. So, a good source of lipase is pancreatic juice. Lipase helps in digestion of fats.

Fats are broken down by lipases with the help of bile into di- and monoglycerides.

$Fats\stackrel{lipases}{\to }Diglycerides\to Monoglycerides$

Then Di and monoglycerides are broken down into fatty acids and glycerol by the action of lipases.

$Diglycerides+monoglycerides\stackrel{Lipases}{\to }Fattyacids+Glycerol$
