The value chain starts with the research that has a clear focus on the identification of targets by analyzing the interaction between the biochemical molecule and its potential therapeutic functionality. In the subsequent development phase, a process for the scale‐up and more consistent manufacturing of the molecule is designed. The target structure is developed into a pharmaceutical form, and tested in animals and humans for safety and efficacy. Pharmaceutical biotechnological products can be classified into: vaccines, therapeutics from blood or animal organs, antibiotics, recombinant proteins, and cell and gene therapeutics. The technological and therapeutic approaches of biotechnology require knowledge of the basic fundamentals of biochemistry. The fascinating functionality of biological systems is founded on biochemical processes. Unfolding of the protein is also referred to as ‘denaturation’, meaning the destruction of the three‐dimensional structure, and typically goes along with a loss of biological activity.
