WebApr 28, 2024 · Emulsification plays a vital role in the breakdown of triacylglycerol (TAG) fats in human digestion. When food reaches the stomach, it mixes with acidic secretions to produce chyme. Small amounts of chyme are then propelled by the pyloric sphincter into the duodenum of the small intestine to continue the digestion process. WebWhat is chyme in biology? Chyme, a thick semifluid mass of partially digested food and digestive secretions that is formed in the stomach and intestine during digestion.
