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). WebLooking at Table 5.2. 1, you see that the pK a of carboxylic acids are in the 4-5 range, the pK a of sulfuric acid is –10, and the pK a of water is 14. Alkenes and alkanes, which are …

WebApr 30, 2024 · $\begingroup$ You seem to think that the pKa of a quaternary salt is the same as the pKa of any other ammonium salt (ie around 9), but that’s not true. The pKa of something is a direct measure of how easily it’s deprotonated. Ammonium salts like R3NH+ are relatively easy to deprotonate, so their pKas are relatively small.

We're going to start with the simplest possible scenario, which is that pH is equal to pK_a. When pH is equal to pK_a, we're raising 10 to the zeroth power. So anything to the zeroth power is equal to one. Which tells us that this ratio is equal to one. do ions need transport protein

In simple terms, pKa is a number that shows how weak or strong an acid is. A strong acid will have a pKa of less than zero. More precisely – pKa is the negative log base ten of the Ka value (acid dissociation constant). It measures the strength of an acid — how tightly a proton is held by a Bronsted acid. do ions have the same atomic number
