Q: Which enzyme is not present in succus entericus?
ANS:
- Nucleases, specifically pancreatic nucleases, are generally absent in intestinal juice (succus entericus).
- These enzymes break down nucleic acids, such as DNA and RNA
- Intestinal juice is primarily secreted by the glands of the small intestine
- Its composition is more focused on carbohydrate and protein digestion.
| Enzyme | Pancreatic Nuclease |
| Source | Secreted by the pancreas |
| Function | Breaks down nucleic acids (RNA and DNA) |
| Substrates | RNA and DNA molecules |
| Presence in Intestinal Juice | Generally absent in intestinal juice (succus entericus) |
| Optimal pH | Generally works optimally at slightly acidic pH |
| Importance | Aids in the digestion of nucleic acids in the small intestine |
| Absorption | Further digestion of nucleic acids occurs in the small intestine through brush border enzymes |
| Clinical Applications | Used in research, biotechnology, and molecular biology techniques |
| Commercial Availability | Available as purified enzymes for laboratory use |
