The carbonic acid molecule has two hydrogen atoms to lose i.e. it is a diprotic acid and, therefore, has two acid dissociation constants, Ka. The value of the acid dissociation constant is the reflection of the strength of an acid.

WebPKA Data In 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 kinase (AMP-activated protein kinase).
