α-D-ribofuranosyl 1,2-cyclic monophosphate, also known as 3',5'-cyclic AMP or cAMP, is a vital second messenger molecule in cells that plays a significant role in signal transduction. It is derived from adenosine triphosphate (ATP) through the action of adenylate cyclase, an enzyme that catalyzes the conversion of ATP to cAMP. cAMP acts as a messenger within the cell, relaying signals from hormones and neurotransmitters to various cellular processes. It binds to proteins called protein kinases, which then phosphorylate other proteins, leading to a cascade of events that regulate cellular functions such as metabolism, gene expression, and cell growth. The balance of cAMP within the cell is tightly regulated by its synthesis and degradation, with phosphodiesterases being the primary enzymes responsible for breaking down cAMP into its constituent parts, thus terminating the signal. This cyclic nature of cAMP's synthesis and degradation is crucial for the precise control of cellular responses to external stimuli.
The CAS Registry Mumber 90275-35-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,2,7 and 5 respectively; the second part has 2 digits, 3 and 5 respectively. Calculate Digit Verification of CAS Registry Number 90275-35: (7*9)+(6*0)+(5*2)+(4*7)+(3*5)+(2*3)+(1*5)=127 127 % 10 = 7 So 90275-35-7 is a valid CAS Registry Number.
