Big Picture: Proteins - Probing Proteins

Use this resource from the Wellcome Trust, as part of the Big Picture: Proteins issue, to learn all about proteins. Proteins are polymers of amino acids, and they do all sorts of incredible things. They give structure to living things, carry messages and molecules around our bodies, support the immune system and catalyse chemical reactions, and they are used widely in industry and medicine too. In this issue, we explore proteins by their different functions and have picked a focus protein for each.
