Answer :
Your muscles, organs, and immune system are all made of proteins. The R-group of an amino acid is what distinguishes it from other amino acids.
Proteins and R-group are the appropriate responses. Proteins are crucial macromolecules that are involved in the formation of muscles, organs, and the immune system, among other functions in the body. The variable component of an amino acid that sets one amino acid apart from another is the R-group (side chain). All amino acids share three basic building blocks: the carboxyl group, the amino group, and the carbon atom.Large molecules known as proteins are made up of one or more chains of amino acids. They are crucial for the structure, operation, and control of tissues and organs in living organisms and play crucial roles in many biological processes.
