Palestine shares most of its borders with Israel, and it borders Jordan to the east and Egypt to the southwest. It has a total land area of 6,020 square kilometres (2,320 sq mi) while its population exceeds five million people. Its proclaimed capital is Jerusalem, while Ramallah serves as its administrative center.

Plastein is a gel-like product of protease-induced peptide aggregation. Plastein is formed by peptide condensation, transpeptidation and physical interaction. Plastein can be used in enhancing protein quality and debittering protein hydrolysates. ...

Plastein is a high-molecular size protease-induced peptide aggregation product. • Plastein reaction has resulted in enhancement of bioactivities of protein hydrolysates. • Proposed peptide rearrangement in plastein can result in new bioactive sequences. • Migration of hydrophobic peptides into plastein core can also mask peptide ...

Also, the term ‘plastein reaction’ is commonly used to refer to the protease-catalysed process involved in the formation of a plastein from a protein hydrolysate or an oligopeptide mixture. However, the definition of the plastein varies somewhat.

2015年3月1日 · Plastein is a gel-like product of protease-induced peptide aggregation. Plastein is formed by peptide condensation, transpeptidation and physical interaction. Plastein can be used in enhancing protein quality and debittering protein hydrolysates. The peptide aggregate also possesses bioactivity related to health promotion.

The theoretical and practical aspects of the plastein reaction, which consists in the formation of a gel following the addition of an endopeptidase to a concentrated solution of a partial protein hydrolysate, are examined and the properties and possibilities

2017年1月8日 · The meaning of PLASTEIN is any of several substances that resemble proteins and are precipitated by the action of proteolytic enzymes (as pepsin or papain) on the digestion products of protein.

2020年8月1日 · Peptides in protein hydrolysates can aggregate into less soluble and higher molecular weight substances in the presence of protease at high substrate concentration. The formed protein-like products are called plastein, which was first described over a century ago (Wasteneys & Borsook, 1924).

2022年1月12日 · The plastein reaction, due to its ability to induce peptide condensation and transpeptidation, is regarded to have the ability to alter the peptide sequences of protein hydrolysates, and shows the potential to modify bioactivities of protein hydrolysates.

Insoluble polypeptide formed through the random condensation of amino acids or peptides under the catalytic influence of a proteinase-like chymotrypsin; molecular weights as high as 500,000 are reported. 2. A gel that is formed on treating a partial hydrolysate of a protein with an endopeptidase. Want to thank TFD for its existence?
