Digestion And Absorption

When lipase catalyzes the hydrolysis of acylglycerol molecules, it breaks the ester bonds linking fatty acids to the glycerol backbone. A diglyceride consists of a glycerol molecule attached to two fatty acids. When both ester bonds are hydrolyzed, the reaction is:$ $Key points to consider:Lipase is an enzyme that catalyzes the hydrolysis (splitting by water) of ester bonds.In the case of a diglyceride (glycerol with two fatty acids attached), complete hydrolysis removes both fatty acids.The final products of the reaction are free fatty acids and glycerol.Among the options provided:Option A (Fatty acids and glucose) and Option B (Glucose and galactose) involve sugars, which are not part of the glyceride structure.Option D (Monoglycerides and glycerol) would be a plausible intermediate product if only one ester bond were hydrolyzed, but complete hydrolysis with lipase would remove both fatty acid groups.Thus, the best answer is:Option C – Fatty acids and glycerol.

Peptones are best described by Option B: partially digested proteins• They’re the water-soluble protein fragments formed when enzymes (like pepsin) hydrolyze larger proteins• Not a zymogen (that’d be pepsinogen) nor the active enzyme itself• They’re simply intermediate digestion products, not a mixture of mucous or bicarbonate
