What are proteins made of? - CORRECT ANSWER-Proteins are made up of amino 
acids linked together by peptide bonds, as well as the R groups attached to the amino 
acids (which make them unique and give certain characteristics) 
Proteins are formed through the process of condensation, when the carboxylic group 
and the amine group of the amino acids bind together to produce water, forming a 
peptide bond.
