Protein IB5
Encyclopedia
The protein IB5 is a human parotid
salivary protein containing several repeats of a short proline
-rich sequence (hence the name of proline rich proteins or PRP for this class of proteins) and known to bind with polyphenol
s (binding responsible for the astringency mouth feel).
Parotid gland
The paired parotid glands are the largest of the salivary glands. They are each found wrapped around the mandibular ramus, and secrete saliva through Stensen's ducts into the oral cavity, to facilitate mastication and swallowing and to begin the digestion of starches.-Location:The parotid glands...
