pKais the negative logarithm of the acid dissociation constant, Ka, which can be measured experimentally. pKavalues have been measured for a large number of molecules and are largely related to the most acidicfunctional grouppresent in the molecule. A pKatable is a useful complication of pKavalue...
Carbonic acid is a neutral molecule. However, carbonic acid is unstable and often dissociates into a proton (which is donated to a base) and bicarbonate, which has a charge of -1. Loss of the other proton yields carbonate, which has a charge of -2....
Ka values can be easily looked up online, and you can find the pKa using the same operation as for pH if it is not listed as well.Online pH and pOH calculator See the Resources for a web tool that allows you to determine the pH of various acidic and basic solutions. You can use ...
The application, primary antibody, and experimental design often determine the type of secondary antibody needed. Use ourantibody search toolto identify the secondary antibody products you need. For more information on all the factors to consider when selecting a secondary antibody,...
which promotes the helical oligomeric assembly of the adaptor molecule ASC. ASC oligomers provide a platform for caspase-1 activation, leading to the proteolytic cleavage and activation of proinflammatory cytokines in the IL-1 family and gasdermin D, which can induce a lytic form of cell death. ...
There is also the role of relays from one part of the thick set to the next, or one part of the memory to the other by electrical signals that may also determine allowance of permanent molecules, conceptually. It is theorized that electrical signals in a set strike at chemical signals, to...
Is 1,3-dibromopropane a chiral compound? Explain. Why does the functional group of a molecule not affect a compound's carbon chain length? How could you use 1H NMR to determine the structure for compound C that has a molecular formula of C6H4Cl2? ...
A buffer is a substance that maintains the pH of a solution. Generally, a buffer contains a conjugate acid/base pair of a weak acid and weak base. If an acid is added to the solution, it will react with the weak base and the pH of the solution will change very ...
It can be assumed that when the nature of the contractile activity of the postural muscle changes, high-energy phosphates and glycogen can act as metabolic signals that affect the state of regulatory networks that determine changes in protein metabolism and myosin phenotype. The...
which are also able to overcome the protecting outer-membrane barrier of Gram-negative bacteria, are of great urgency1. Albicidin is a phytotoxic small molecule synthesized by the Gram-negative plant pathogenXanthomonas albilineansthat causes leaf scald disease in sugarcane plants2. Besides its phyt...
