"WebIn cell biology, protein kinase A (PKA) is a family of enzymes whose activity is dependent on cellular levels of cyclic AMP (cAMP). PKA is also known as cAMP-dependent protein kinase (EC 2.7.11.11).PKA has several functions in the cell, including regulation of glycogen, sugar, and lipid metabolism.It should not be confused with 5'-AMP-activated protein … " - De pka a ka

WebThe lesser the pKa is, the molecule would hold proton less tightly; hence the more potent the acid will be. Ka is the acid dissociation constant. It is used to determine how much an acid dissociates in solution. The larger the Ka, the higher would be dissociation. Hence stronger would be the acid. pKa is related to Ka as, pKa = – log[Ka] WebAug 13, 2024 · Re : K = 10^pka2-pka1. Il est plus judicieux de classer les couples acide/base en fonction des pKa. On visualise mieux le fait que plus l'acide est fort, plus sa base conjuguée est faible et plus le pKa est faible. L'intérêt d'orienter l'axe des pKa vers le bas donne une analogie assez forte avec le classement des couples oxydant/réducteur.
