Adenosine monophosphate (AMP)

Definition

Adenosine monophosphate (AMP) is a nucleotide composed of adenine, ribose, and one phosphate group. It plays a crucial role in cellular energy transfer and metabolism.

5 Must Know Facts For Your Next Test

1. AMP is a product of ATP hydrolysis and can be converted back to ATP through phosphorylation.
2. It serves as an important regulatory molecule in metabolic pathways, influencing enzyme activity.
3. AMP can be formed from ADP or by the breakdown of cyclic AMP (cAMP).
4. The concentration of AMP within a cell is a key indicator of the cell's energy status.
5. AMP-activated protein kinase (AMPK) is activated by high levels of AMP, promoting energy-producing processes.
