Five digestive enzymes that are secreted by the intestinal glands are peptidases, sucrase, maltase, lactase and intestinal lipase. These enzymes are important in the process of digestion.
Proteases and peptidases spril proteins into amino acids lipases split fat into three fatty acids glycerol, carbohydrases split carbohydrates nucleases split nucleic acids into nucleotides
In the case of protein digesting enzymes, known as endopeptidases, such as those secreted in the stomach (pespin), it is obvious. If they were secreted active they would digest the glands which secrete the enzymes themselves (gastric glands). Instead they must be secreted in an inactive form, which once in the stomach and exposed to HCl acid and other pepsin enzymes the pepsinogen activates and begins digesting protein.
Thyroid glands and intestinal glands
Technically, most named digestive enzymes and secretions are made by glands located outside of the "tube" of the gastrointestinal tract. For instance, the salivary glands are located between the muscles of the jaw and face, and secrete saliva into the mouth through salivary ducts. Bile is created by the liver, stored in the gallbladder and then secreted into the small intestine; pancreatic enzymes (there are a bunch of them) are made in the pancreas then secreted into the small intestine as well.
Ecolysis
Intestinal glands are located in the epithelial lining of the small intestine and colon. What happens when the intestinal glands secrete intestinal juice is that trypsin activates other enzymes to aid in protein digestion.
I'm not sure.. but I think those are: Salivary Glands Gastric Glands Bile Glands Pancreatic Glands Intestinal Glands
endocrine gland
gastric glands
A frog digestive system has 2 parts which are Alimentary canal and Digestive glands. The digestive glands includes gastric glands, liver, pancreas, and the intestinal glands.
Salivary glands.
Sucrase is a family of enzymes. Some of it is secreted from the salivary glands in the mouth but most of the sucrase activity is in the small intestines. In the intestines it is not secreted, but rather, contained in the wall.
