Question : Describe various components present in pancreatic juice. |
|
Answer» Solution :Semi digested food chyme comes to intestine by pyrrolic stomach. Chyme comes into contact of three different secretions in small intestine. Pancreatic juice, bile juice and intestinal juice. Various types of movements are generated by the muscularis layer of the small intestine. These movements help in a thorough mixing up of the food with various secretions in the intestine and there by facilitate digestion. Pancreatic juice possesses inactive enzymes trypsinogen, chymotrypsinogen and procarboxypeptidases and AMYLASE, lipase and nuclease. Trypsinogen is activated by an enterokinase, secreted by the intestinal mucosa into active trypsin which in turn activates the other enzymes in the pancreatic juice. Proteases + PEPTONES `overset"Trypsin"to` polypeptide + Amino ACID Trypsin convents chymotrypsinogen into chyme trypsin and procarboxy peptidases in to carboxyl peptidase. proteoses + polypeptides + peptones `to`Chymotrypsin small polypeptide + Amino Acid. Polypeptide `overset"Carboxypoptidose"to` Peptide, Amino acid Amylase PRESENT in pancreatic, juice hydrolyses carbohydrates and disaccharide is formed. Polysaccharide (starch `overset"Amylase"to`Disaccharide Maltese). The bile released into the duodenum contains bile pigments (bilirubin and biliverdin), bile salts, cholesterol and phospholipids but no enzymes. Bile helps in EMULSIFICATION of fats i.e. breaking down of the fats into very small micelles. Fats `overset"Lipases"to` Diglycerides `to` Monoglycerides Nucleases of pancreatic juice reacts on nucleic acid and forms nucleotides and nucleosides. Nucleic acids `overset"Nucleases"to` Nucleotides `to` Nucleosides Digestion by intestinal juice in Jejunum and ileum: The enzymes of intestinal juice react on enzymes, final products react on them and convert into absorbable simple form. Dipeptide `underset"(Erepsin)"overset"Dipeptidases"to` Amino Acids Maltose `overset"Maltase"to` Glucose + Glucose Lactose `overset"Lactose"to` Glucose + Galactose Sucrose `overset"Sucrose"to` Glucose + Fructose Nucleotides `overset"Nucleotidases"to` Nucleosides `overset"Nucleosidases"to` Sugars+ `N_2` Bases Di and Monoglycerides `overset"Lipases"to` Fatty acid+Glycerol Simple components produced from bio mega molecules are absorbed into jejunum and ileum of small intestine. Undigested and unabsorbed components are passed into large intestine. |
