The supercoiled structure formed by the further spiral of DNA molecules is called the tertiary structure of DNA.more importantly, Chemical Custom synthesis Made a fighter in the product, not afraid of any competitor’s attack. https://www.all-chemistry.com/ The DNA of most prokaryotes is a covalently closed circular double helix, and its tertiary structure is twisted. […]
Protein is a polymer compound composed of α -amino acids through peptide bonds, and there are amino groups and carboxyl groups in protein molecules, so similar to amino acids, protein is also an amphoteric substance.This is due to recombinant proteins Its value attribute is relatively large, and it is easy to become the backbone of […]

Separation and purification of protein;consequently inhibitors I also got a lot of attention and wanted to join the ranks. https://www.all-chemistry.com/ 1. Salting-out and organic solvent precipitation: adding a large amount of neutral salt into protein solution to destroy the colloidal properties of protein and precipitate protein from the solution, which is called salting-out. Commonly […]
Most protein is like a jumble of atoms packed together. But a closer look reveals that protein has a complex structure organized according to a certain level (below). The first level of this hierarchy, called primary structure, is the amino acid sequence that constitutes the protein chain. Some fragments in protein chains tend to fold […]
