Protein characterization

Definition

Protein characterization is the process of identifying and analyzing the structure, function, and properties of proteins. This involves techniques that help determine aspects like molecular weight, amino acid composition, and three-dimensional structure. Understanding protein characterization is essential in the context of advances in parasite genomics and proteomics, as it helps researchers uncover the roles proteins play in parasite biology and their interactions with hosts.
