This is a carbohydrate-protein complex that protects the oral cavity from abrasion.
Answers
Answer:
The carbohydrate- protein complex that protects the oral cavity from abrasion is called Mucin.
Explanation:
As soon as the food is taken, our mouth starts its chemical and physical digestion. A nervous reflex is triggered due to the presence of food in the mouth. This nervous reflex passes signals to deliver saliva from the salivary glands to the oral cavity.
Saliva contains the glycoprotein called mucin which is majorly involved in protecting the oral cavity from abrasion as well as lubrication of the food so that it can be swallowed easily.
Answer:
Mucin is the carbohydrate-protein complex that protects the oral cavity from abrasion.
Explanation:
Mucin is a glycoprotein that is found in saliva. They are hydrophilic in nature and retain much water. This helps in resisting dehydration of mucosal layers. Mucin also binds with bacterial surfaces thereby preventing bacteria from colonizing the oral cavity.
These bacteria will be destroyed by the gastric juice after being swallowed. Mucin also binds with masticated food making it slippery and easy to slide through the oesophagus.
