Pyrroloquinoline quinone (PQQ) is a fascinating compound that has garnered attention in the fields of nutrition, biochemistry, and regenerative medicine over the past few decades. Identified as a redox cofactor, PQQ plays a crucial role in various biological processes, particularly in mitochondrial function and energy metabolism. One of the key parameters that influences its efficacy and stability within the body is its half-life.
APIs can be classified into two main categories small molecules and biologics. Small molecules are typically low molecular weight compounds that can be administered orally and are often used in conventional medications. On the other hand, biologics are larger, more complex molecules produced through biotechnological means, such as proteins, monoclonal antibodies, or vaccines. Each category presents unique challenges in terms of production, stability, and delivery methods.
