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 these articles, we explore proteins and discover how they are involved in all kinds of processes in humans and other organisms.
