[BIOCHEMISTRY] Introduction: Nucleic Acid

Serves as predominant second messenger

It controls enzymatic reaction through allosteric effect on enzyme activity

It serves as mediator of numerous important cellular process like second messenger

It serves as energy store for future use in phosphate transfer reaction

It serves as activated intermediates in numerous biosynthetic reaction

Derivatives of purine bases

Derivatives of pyrimidine bases

Most common adenosine derivative

Very powerful second messenger involved in passing signal transduction event from cell surface to internal protein

Compound which is involved in regulation of ion channels by direct interaction with channel proteins

Most common guanosine derivative

A compound that antagonize the effect of cAMP

It is formed by the condensation of two or more nucleotides
