how are trypsin and chymotrypsin different?
444319
The main difference between chymotrypsin and trypsin is the amino acids they select for. Chymotrypsin is the enzyme that selects for the aromatic amino acids: phenylalanine, tryptophan, and tyrosine. Trypsin is the enzyme that selects for the basic amino acids: lysine and arginine.

Enzyme Functions and Denaturation. An enzyme is a biological protein molecule made up of thousands of amino acids. ... Enzymes work consistently until they are dissolved, or become denatured. When enzymes denature, they are no longer active and cannot function.

A peptide is two or more amino acids joined together by peptide bonds; a polypeptide is a chain of many amino acids; and a protein contains one or more polypeptides. ... The order of deoxyribonucleotide bases in a gene determines the amino acid sequence of a particular protein.

Chymosin, known also as rennin, is a proteolytic enzyme related to pepsin that synthesized by chief cells in the stomach of some animals. Its role in digestion is to curdle or coagulate milk in the stomach, a process of considerable importance in the very young animal.

Ptyalin is an enzyme and therefore it is made up of protein. when it enters the stomach, the HCL in the stomach denatures the protein and thus ptyalin becomes inactive or the activity stops. Pytalin is an enzyme. The High acidity in the stomach denatures this enzyme.

Both reactions are highly specific because they depend on the specific antibody and antigen pair. The main difference between these two reactions is the size of antigens. For precipitation, antigens are soluble molecules, and for agglutination, antigens are large, easily sedimented particles.

While both are biomarkers for inflammation, ESR and CRP should be interpreted differently. Due to this basic physiologic difference, CRP is a more sensitive and accurate reflection of the acute phase of inflammation than is the ESR.

The main difference between pepsin and trypsin is that the pepsin is secreted by the gastric glands of the stomach whereas the trypsin is secreted by the exocrine glands of the pancreas. ... Pepsin and trypsin are two types of proteolytic enzymes secreted by the digestive system in order to digest proteins.

Both peptides and proteins are made up of strings of the body's basic building blocks – amino acids – and held together by peptide bonds. In basic terms, the difference is that peptides are made up of smaller chains of amino acids than proteins.

Treatment of HMM with the protease papain cleaves the two globular heads from the tail section (S2). The two heads (termed S1) are not surprisingly found to be the site of ATPase activity; they also bind to actin filaments. ... Myosin is therefore unusual in that it is both a fibrous protein, and a globular enzyme.

The pancreas secretes zymogens partly to prevent the enzymes from digesting proteins in the cells in which they are synthesised. ... Another way that enzymes can exist in inactive forms and later be converted to active forms is by activating only when a cofactor, called a coenzyme, is bound.

The optimum temperature and pH for the trypsin are 65 °C and pH 9.0, respectively. Also, the enzyme can be significantly activated by Ba2+. This enzyme is relatively stable in alkaline environment and displays excellent activity at low temperatures.

Trypsin is a proteolytic enzyme, important for the digestion of proteins. In humans, the protein is produced in its inactive form, trypsinogen, within the pancrease. Trypsinogen enters the small intestine, via the common bile duct, where it converted to active trypsin.

Pepsin works in the highly acidic conditions of the stomach. It has an optimum pH of about 1.5. On the other hand, trypsin works in the small intestine, parts of which have a pH of around 7.5. Trypsin's optimum pH is about 8.

From the Stomach to the Small Intestine The two major pancreatic enzymes that digest proteins are chymotrypsin and trypsin. The cells that line the small intestine release additional enzymes that finally break apart the smaller protein fragments into the individual amino acids.

Trypsin is an enzyme that helps us digest protein. In the small intestine, trypsin breaks down proteins, continuing the process of digestion that began in the stomach. It may also be referred to as a proteolytic enzyme, or proteinase. Trypsin is produced by the pancreas in an inactive form called trypsinogen.
