WebpKa. pK a is defined as the negative log 10 of the dissociation constant of an acid, its K a.Therefore, the pK a is a quantitative measure of how easily or how readily the acid gives up its proton [H +] in solution and thus a measure of the "strength" of the acid.Strong acids have a small pKa, weak acids have a larger pKa. The most common acid we will talk … WebJun 3, 2008 · Signaling through the cyclic adenosine monophosphate–dependent protein kinase [protein kinase A (PKA)] is an important and widely studied area of signal transduction research.

In organic chemistry, a thiol , or thiol derivative, is any organosulfur compound of the form R−SH, where R represents an alkyl or other organic substituent. The −SH functional group itself is referred to as either a thiol group or a sulfhydryl group, or a sulfanyl group. Thiols are the sulfur analogue of alcohols (that is, sulfur takes the place of oxygen in the hydroxyl (−OH) group of an alcohol), and the word is a blend of "thio-" with "alcohol".
