Homolytic cleavage isthe breaking of a covalent bond in such a way that each fragment gets one of the shared electrons. The word homolytic comes from the Greek homoios, "equal", and lysis, "loosening". ... Bond cleavage is the splitting of a chemical bond. There are two types of bond...
A Biuret test is achemical test used to determine the presence of a peptide bond in a substance. It is based on the biuret reaction in which a peptide structure containing at least two peptide links produces a violet color when treated with alkaline copper sulfate. What is the biuret test?

Different minerals, like aragonite (CaCO3) and calcite (CaCO3), can have the same chemical makeup, but their crystal structure and physical properties differ because of how they each formed. "For each mineral, they will have a set way that those atoms bond together," Anderson said. "Some...
of hen lysozyme has been determined using 209 residual 1H-15N dipolar coupling restraints from measurements made in two different dilute liquid crystalline phases (bicelles) in conjunction with a data set of 1632 NOE distance restraints, 110 torsion angle restraints, and 60 hydrogen bond restraints....
What's New in KnowItAll 2025. Wiley’s KnowItAll spectral software offers solutions to identify, analyze, and manage analytical and chemical data.
so classifying things as molecules based on bond type was unwise. This has led to a very broad definition of molecule that is typically accepted and understood today—two or more atoms that are connected through chemical bonding with a fixed number of atomic nuclei. As mentioned above, all com...
This is what makes nanotape so useful – with two surfaces that are always different, it can be used to bond dissimilar materials together, just like Sellotape but on a microscopic scale. For example, it could be used to coat the inside of an artificial plastic blood vessel. The hydrophobic...
On Thursday, 31 May the exhibition will focus on young people and students. As the baby boomers retire, new job positions will open up throughout the forest industry. UPM requires a new kind of expertise especially in chemical industries and new businesses. ...
