Whether the statement “about 50% of TAGs undergo complete hydrolysis in the stomach” concerning to triacylglycerol(TAG) digestion is true or false has to be determined. Concept introduction: Triacylglycerols are lipid molecules which constitute around 98% of the total dietary lipids. These lipid molecules undergo digestion/breakdown into simpler forms in the digestive system and are later absorbed into the bloodstream. In the bloodstream, the hydrolysis products of triacylglycerols (fatty acids and glycerol) are absorbed by the body cells and are either broken down into acetyl CoA or stored as lipids for future use. Fats/Lipids are a richer source of energy compared to carbohydrates. While carbohydrates provide energy for immediate use, lipids provide energy for long term or future use.

Question

Definition Definition Organ system that helps in the digestion of food by mechanical and biochemical processes. The digestive system breaks down food into simpler components that enable the body to then absorb or transport nutrients. The human digestive system includes the gastrointestinal tract or alimentary canal and the associate glands. The organs of the gastrointestinal tract include the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. The associated glands include salivary glands, liver, gallbladder, and pancreas.
