Health is the level of functional and metabolic efficiency of a living organism.

In humans it is the ability of individuals or communities to adapt and self-manage when facing physical, mental or social changes.

The World Health Organization (WHO) defined health in its broader sense in its 1948 constitution as "a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity."

Various forms of life exist, such as plants, animals, fungi, protists, archaea, and bacteria.

The criteria can at times be ambiguous and may or may not define viruses, viroids, or potential artificial life as "living".

Adenosine monophosphate (AMP), also known as 5'-adenylic acid, is a nucleotide that is used as a monomer in RNA.

It is an ester of phosphoric acid and the nucleoside adenosine, which does not have the typical high energy bond of the so called adenosine monophosphate ("AMP") that arises on the hydrolysis of ATP.

AMP consists of a phosphate group, the sugar ribose, and the nucleobase adenine.

As a substituent it takes the form of the prefix adenylyl-.
