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 … WebAcide faible Base conjuguée faible pKa HO+ 3 H2O - 1,75 HClO3 − ClO3 0 Acide picrique HB B− 0,38 Acide trichloracétique HB B− 0,66 Acide benzène sulfonique HB B− 0,7 …
