Webb1 maj 2024 · The pKa of molecule A is known to be 7.09, but the pKa of molecule A+ is not known. How can any change in protonation state of molecule A+ be predicted given only this information? Note that this question is NOT asking the protonation state of a molecule if we know THAT molecule's pKa and if we know how ITS pKa changes ( for example, as … Webb22 feb. 2012 · New residue descriptors for the unprotonated and cis and trans protonated forms of the product imine formed between the T4PDG Thr1 amine and the ring–opened abasic site deoxyribose aldehyde, (R)– and (S)–configurations at the chiral center of the protonated and unprotonated forms of the carbinolamines, the ring–opened deoxyribose …

WebbThe reaction of ninhydrin with an -amino acid occurs in several steps (a) The first step is loss of water to give a triketone. Show the mechanism of the reaction and the structure of the triketone.(b) The second step is formation of an imine by reaction of the amino acid with the triketone. Show its structure.
