The specific amino acid sequence is always decisive.  <\/p><p>In everyday life, peptides are often confused with food supplements or medicine. In chemical terms, they are defined molecules that can be present in various forms, for example as a lyophilized powder for laboratory purposes. For practical work, it is important that identity and purity are documented in a traceable manner and that storage and handling are appropriate for stability.
