The resulting amide bond called a peptide bond is a carbon to nitrogen (C-N) covalent bond that now links the two amino acids together to form a dipeptide. The sequence (order) of the amino acids is critically to the functionality of the protein. In order for this reaction to take ...
the final nitrogen–oxygen bond is a specific type of covalent bond, called a coordinate covalent bond. A coordinate covalent bond is a covalent bond where the pair of electrons forming the bond is donated from one atom only. In this case, the pair of valence electrons come from the nitroge...

Chemical doping is one of the most important strategies for tuning electrical properties of semiconductors, particularly thermoelectric materials. Generally, the main role of chemical doping lies in optimizing the carrier concentration, but there can potentially be other important effects. Here, we show ...
The human immune system is composed of a distributed network of cells circulating throughout the body, which must dynamically form physical associations and communicate using interactions between their cell-surface proteomes1. Despite their therapeutic potential2, our map of these surface interactions rem...
Chalcogenides of a predominantly covalent bond type also form covalent-polymer bonding systems in the melt, whereas tellurides on melting change in a way which leads to a higher coordination number and a more metallic character of the melt. The formation of associates in the fused state makes ...
In an electron-dot symbol of an element, the dots are used to represent ___. a. all of the electrons in the atom b. the valence electrons c. the electron arrangement d. only the electrons that will participate in bond formation e. the electron What is the...
I need to determine what type of covalent bond SiC2 (silicon dicarbide) and so creating the lewis dot diagram is helpful. I know I have 12 electrons available but I can't seem to draw it :/ Physics news on Phys.org Tilted magnetic materials offer fresh path for thermoelectric applicatio...
