WebIn genetics, crosslinking of DNA occurs when various exogenous or endogenous agents react with two nucleotides of DNA, forming a covalent linkage between them. This … In chemistry and biology a cross-link is a bond or a short sequence of bonds that links one polymer chain to another. These links may take the form of covalent bonds or ionic bonds and the polymers can be either synthetic polymers or natural polymers (such as proteins). In polymer chemistry "cross-linking" … See more Crosslinking is the general term for the process of forming covalent bonds or relatively short sequences of chemical bonds to join two polymer chains together. The term curing refers to the crosslinking of thermosetting resins, … See more Proteins naturally present in the body can contain crosslinks generated by enzyme-catalyzed or spontaneous reactions. Such crosslinks are important in generating mechanically stable structures such as hair, skin, and cartilage. Disulfide bond formation is one of the most … See more Crosslinking is often measured by swelling tests. The crosslinked sample is placed into a good solvent at a specific temperature, and either the change in mass or the change in volume is measured. The more crosslinking, the less swelling is … See more Wide usage of the term cross-linking is also described as vulcanization in material science and engineering, mainly addressing the fast reaction between monomers and polymers and branches of rubber. Cross-linking or interlinking m of polymers can … See more • Branching (polymer chemistry) • Cross-linked enzyme aggregate • Cross-linked polyethylene (PEX) See more • Application note on how to measure degree of crosslinking in plastics See more

WebThe cross-linking theory of aging (also known as the glycosylation theory of aging) attributes aging to chemical changes that happen in the body. … As cross-linked proteins accumulate over time they will damage cells and tissues, resulting in increased tissue stiffness and slowing down processes within the body. WebThe Cross-Linking Theory: also referred to as the Glycosylation Theory of Aging. In this theory it is the binding of glucose (simple sugars) to protein, (a process that occurs under the presence of oxygen) that causes various problems. Once this binding has occurred the protein becomes impaired and is unable to perform as efficiently. WebChemistry of Crosslinking. Crosslinking is the process of chemically joining two or more molecules by a covalent bond. The technique, often called bioconjugation when referring to its use with proteins and other biomolecules, is an essential component of many proteomics methods, including creation of detectable probes for western blotting and ... is blue advantage bcbs
