Digestion of dietary lipid

The effect of dietary lipid supplementation on digestion and synthesis in the stomach of sheep.

Lingual lipase and its role in the digestion of dietary lipid.

The serous glands of rat tongue were found to contain a potent lipolytic enzyme which hydrolyzed triglyceride to mostly diglyceride and free fatty acids (FFA) at pH 4.5-5.4. Homogenates of lingual serous glands from adult rats hydrolyzed 40-70 mmol of triglyceride/g per h. The soft palate, anterior oral pharyngeal wall, and lateral oral pharyngeal glands also contained the activity, but at a mu...

Significance of Intestinal Digestion of Dietary Protein

In the last twenty years, elaborate models have been developed to formulate diets with greater accuracy in meeting the protein and amino acid requirements of lactating dairy cattle. Models for feeding protein to dairy cattle in the USA evolved from basic crude protein (NRC, 1978) to more complex systems based on rumen undegraded protein (RUP) and intestinal digestion of RUP (NRC, 2001). The NRC...

Principles of Physiology of Lipid Digestion

The processing of dietary lipids can be distinguished in several sequential steps, including their emulsification, hydrolysis and micellization, before they are absorbed by the enterocytes. Emulsification of lipids starts in the stomach and is mediated by physical forces and favoured by the partial lipolysis of the dietary lipids due to the activity of gastric lipase. The process of lipid diges...

Physiological role of dietary free glutamate in the food digestion.

Gustatory and anticipatory cephalic stimuli during a meal yield nutritional information and aid efficient food digestion. Mammals, including humans, can detect the amount of dietary protein and its quality via cephalic relay to initiate proper digestion in the upper gastrointestinal (GI) tract. In addition to gustatory stimuli, visceral sensing by the abdominal vagus conveys primary afferent nu...
