Objectives
After completing this section, you should be able to
- give examples of the various biological roles played by proteins.
- identify amino acids as being the building blocks from which all proteins are made.
- show, in a general way, how the joining together of a number of amino acids through the formation of peptide bonds results in the formation of proteins.
Make certain that you can define, and use in context, the key terms below.
- amino acid
- enzyme
- peptide bond
- protein
The “peptide bond” or “peptide linkage” that is formed between the amino group of one amino acid and the carboxyl group of a second amino acid is identical to the C$\ce{-}$N bond present in amides (see Section 21.7). We shall review the nature of such bonds in Section 26.4.
