Proteins are chains of amino acids, and these chains have an Nitrogen-terminus and a Carbon-terminus. The Nitrogen-terminus is the end of the protein that has a nitrogen, which is available for bonding with a free carbon of another amino acid. The carbon-terminus is the end of the protein that has a carbon which is available to bond with a free nitrogen of another amino acid.
Trypsin can cleave a bond between argininel and another amino acid or lysine and another amino acid. The reason why the N-terminus and C-terminus is important is because enzymes either N-terminus specific or C-terminus specific. Trypsin, for example will cleave bonds between arginin or lysine and the amino acid it is bonded closes to the C-terminus side (see below).
(N-terminus) Alanine--Lysine--Glycine (C-terminus) ----> Alanine--Lysine + Glycine
In this example trypsin hydrolyzed the bond between lysine and glycine, which was the bond on the C-terminus end. It would not effect the bond with alanine because it is on the N-terminus side.

∙ 9y agoThe chief substrates of chymotrypsin are tryptophan, tyrosine, phenylalanine, leucine, and methionine. These are all cleaved at the carboxyl terminal.

Why trypsin is valuable?
Trypsin is a key digestive enzyme that assists with breaking down proteins and polypeptides. Trypsin also helps activate other enzymes like chymotrypsin.
Why can't maximum initial reaction rates be reached at low substrate concentrations?
The maximum cannot be reached because there are not enough substrates available to react. In other words, the rate cannot be, say, 350 (x10^6) molecules of product formed per minute unless there are enough substrates available to create that many products. The substrates would simply be converted and then it would be over.
What are molecules that are acted upon by enzymes called?
These molecules are called substrates.
Where are lipase and trypsin produced?
Its incative form, trypsinogen, is secreted from the pancreas....
Why do you wash cells with PBS before adding trypsin?
Because PBS removes Magnesium and Calcium ions which inhibit trypsin.
What has the author Joseph John Oliver Smyth written?
Joseph John Oliver Smyth has written: 'The synthesis and activity of new specific substrates and inhibitors of trypsin and chymotrypsin'
What is the enzyme product for carbohydrase?
The substrates of cellulase is cellulose.
When an enzyme catalyzes a reaction do Substrates bind in the active site or do Products bind in the active site?
Substrates. Once the enzyme and the substrate combine, on the product is created.
What do Trypsin and chymotrypsin digest?
Trypsin breaks down Peptides to Amino Acids
Are pepsin and trypsin classified as sugars?
pepsin and trypsin are classified as proteins
What pH does trypsin work at the best?
The optimal pH for trypsin is 8. It is found in the small intestine and digests proteins and polypeptides there.
What are the similarities of pepsin and trypsin?
Pepsin and trypsin both are protein digesting enzymes.
Why trypsin is valuable?
Trypsin is a key digestive enzyme that assists with breaking down proteins and polypeptides. Trypsin also helps activate other enzymes like chymotrypsin.
Are substrates proteins?
There are protein substrates, but not all substrates are proteins. Lipid, carbohydrates, nucleic acids can also act as substrates to its specific enzyme. but enzyme can be only proteins and not Lipid, carbohydrate.
How serum use to stop the trypsin action?
serum is going to stop the action of trypsin, because it contain the inhibitors of trypisn. Once you will inhit you can see the function of trypsin. SK
In the exercise concerning trypsin function why was an enzyme assay like Benedict's or Lugol's IKI which test for the presence of a reaction product not necessary?
proteins do not contain sugar
Do mushrooms have substrates?
Yes. Substrates should be rich in organic matter.
