noun
definition
A digestive enzyme that cleaves peptide bonds (a serine protease)
Examples of trypsin in a Sentence
A third enzyme, the trypsin of the pancreas, possesses the power of both pepsin and erepsin.
This amyloid substance is slowly and imperfectly digested by pepsin - digestion being more complete with trypsin and by autolytic enzymes.
That such enzymes are formed in the protoplasm is evident from the behaviour of hyphae, which have been observed to pierce cell-membranes, the chitinous coats of insects, artificial collodion films and layers of wax, &c. That a fungus can secrete more than one enzyme, according to the materials its hyphae have to attack, has been shown by the extraction of diastase, inulase, trehalase, invertase, maltase, raffinase, malizitase, emulsin, trypsin and lipase from Aspergillus by Bourquelot, and similar events occur in other fungi.
The secretion of trypsin by the pancreas may therefore be looked upon as the formation of a toxin.
We do not know at present if any corresponding anti-toxin or antitrypsin, as we may term it, is returned into the lymphatics or blood from the gland, but the pancreas, which in addition to secreting trypsin secretes a diastatic ferment forming sugar from starch, pours this into the intestine and secretes at the same time a glycolytic ferment which breaks up sugar, and this latter passes into the blood by way of the lymphatics.
A remote controlled gel cutter dispenses samples into 96-well plates for trypsin digestion and mass analysis.
In peptide mass mapping the resolved proteins are digested with trypsin and the derived peptides accurately sized using mass spectrometry.
We then use trypsin to ' shave ' the solvent exposed peptides from the integral PM proteins.
The test measures immunoreactive trypsin (IRT) assays on blood spots.
Removal of part of the peptide using the enzyme trypsin restores the native structure of the virus.
The two proteases trypsin and chymotrypsin are grouped into the serine protease family.
For example, the trypsin of the pancreas (see Nutrition) digests albuminous bodies in neutral or alcoholic solution, and if the whole of that which is secreted in the pancreas for the digestion of meat in the intestine were absorbed unchanged into the circulation, it would digest the body itself and quickly cause death.
Hemp seed does not contain the anti-nutrient trypsin inhibitors found in soya milk.
This is the case in the trypsin family of serine proteases, examined in more detail later in this section.
This condition is due to a deficiency of the enzyme trypsin and other digestive enzymes produced in the pancreas.
