4). The molecular structure may be in ring form. Chemical compounds with the same molecular formula but different structural formulas is called an isomer. Functional Groups: These are certain groups of atoms attached to the carbon skeleton. This area is usually on the end of the molecule. 1....

Cyclic lipopeptides (CLPs) produced by the genus Bacillus are amphiphiles composed of hydrophilic amino acid and hydrophobic fatty acid moieties and are biosynthesised by non-ribosomal peptide synthetases (NRPSs). CLPs are produced as a mixture of homolo
Recently, the CRISPR/Cas12a system integrated with nucleic acid amplification has increasingly shown tremendous potential in microorganism detection. However, a general quantification strategy for total bacteria count based on the CRISPR/Cas12a system has not yet been developed. Herein, we established a...

Solubility – Varying aromatic substituents to vary pKa We can change the pKa of an aromatic amine or carboxylic acid by adding electron-donating or withdrawing substituents to the ring! Remember the position of such a substituent can affect a more distant group through induction and/or resonance ...
