Lipase, primarily pancreatic lipase, hydrolyzes triglycerides into monoglycerides and free fatty acids in the small intestine, aided by bile salts that emulsify fats. Amylase digests starch, pepsin proteins, sucrase sucrose. Lipases are also secreted by lingual and gastric glands but pancreatic lipase is the main.

Explanation:
The periderm is the outer protective covering of stems and roots that have undergone secondary growth (thickening), replacing the primary epidermis. It is composed of three distinct layers: 1) Phellem (cork): The outermost layer, consisting of dead, compactly arranged cells with suberized (waterproof) walls that provide protection and prevent water loss. 2) Phellogen (cork cambium): The middle, meristematic layer that produces phellem outwards and phelloderm inwards. 3) Phelloderm (secondary cortex): The innermost layer, consisting of living, parenchymatous cells.
