in which layer of the intestine does most chemical digestion take place?
small intestine
digestion is the first step to lipid metabolism, and it is the process of breaking the triglycerides down into smaller monoglyceride units with the help of lipase enzymes. digestion of fats begin in the mouth through chemical digestion by lingual lipase. ingested cholesterol is not broken down by the lipases and stays intact until it enters the epithelium cells of small intestine. lipids then continue to the stomach where chemical digestion continues by gastric lipase and mechanical digestion begins (peristalsis). the majority of lipid digestion and absorption, however, occurs once the fats reach the small intestines. chemicals from the pancreas (pancreatic lipase family and bile salt-dependent lipase) are secreted into the small intestines to help breakdown the triglycerides, along with further mechanical digestion, until they are individual fatty acid units able to be absorbed into the small intestine's epithelial cells. it is the pancreatic lipase that is responsible for signaling for the hydrolysis of the triglycerides into separate free fatty acids and glycerol units.
lipid metabolism
in the large intestine the passage of food is slower to enable fermentation by the gut flora to take place. here water is absorbed and waste material stored as feces to be removed by defecation via the anal canal and anus.
