Analysis of Peptides & Proteins
Proteins are a versatile group of macromolecules; peptides are smaller in size with a limited number of building stones. Both consist out of a chain of amino acids, their structure is determined not only by the amino acids, but also by interactions between them, forming a secondary and tertiary structure which is important for the activity of the molecule and its chemical and physical characteristic.
Proteins are present in all cells, functioning e.g. as enzymes, as transmitters or as biomarkers. Understanding about conditions and mechanism of their expression or absence is crucial for further development of biopharmaceuticals for a targeted therapy of diseases.
