In food science and in many informal contexts, the term carbohydrate often means any food that is particularly rich in the complex carbohydrate starch (such as cereals, bread and pasta) or simple carbohydrates, such as sugar (found in candy, jams, and desserts).hile the scientific nomenclature of carbohydrates is complex, the names of the monosaccharides and disaccharides very often end in the suffix-ose.

It is found at the border of the stomachâs final segment, the pylorus, and the small intestineâs first segment, the duodenum. Continue Scrolling To Read More Below...
Pyloric Sphincter. The pyloric sphincter is a band of smooth muscle at the junction between the pylorus of the stomach and the duodenum of the small intestine. It plays an important role in digestion, where it acts as a valve to controls the flow of partially digested food from the stomach to the small intestine.he pyloric sphincter prevents the regurgitation of chyme from the duodenum into the stomach. It also controls the flow of chyme into the intestine, which provides the intestines with a manageable volume of chyme from which to absorb nutrients.
