ATP (Adenosine Triphosphate) was first isolated from muscle and liver extracts by Karl Lohmann in 1929.
The Discovery of ATP: A Closer Look
Here's a breakdown of how ATP, the "energy currency" of cells, was discovered:
-
Initial Isolation: Karl Lohmann, a German biochemist, is credited with first isolating ATP in 1929. He extracted it from muscle and liver tissues. This marked the beginning of our understanding of ATP's crucial role in biological systems.
-
Recognition as Life's Energy Reservoir: Following its isolation, ATP was quickly recognized as a key energy-storage and transfer molecule within cells. This discovery was groundbreaking, as it started to explain how cells power their various functions. The reference states that since its isolation, ATP has been regarded as life's energy reservoir.

Key Biological Functions:
- ATP is a fundamental component of RNA.
- It acts as a substrate for the initial step of protein synthesis.
- Through protein phosphorylation, ATP plays a vital role in cellular signaling processes.
Understanding ATP's Role
Here's a simple analogy to illustrate ATP's role:
Imagine ATP as a tiny, rechargeable battery. When the cell needs energy to perform a task, such as muscle contraction or protein synthesis, it "spends" an ATP molecule. This "spending" involves converting ATP into ADP (Adenosine Diphosphate), releasing the stored energy. ADP can then be "recharged" back into ATP, ensuring a continuous supply of energy for cell activities.
Significance of ATP Discovery
The discovery of ATP was fundamental to understanding:
- How cells function at a molecular level.
- The processes that generate and utilize energy in living organisms.
- Mechanisms of metabolic pathways.
In summary, Karl Lohmann’s isolation of ATP from muscle and liver extracts in 1929 laid the foundation for our understanding of cellular energy transfer. It is a cornerstone of modern biochemistry, revealing a molecule essential for virtually all life processes.
