Study Notes
Building Blocks of Proteins
- Amino acids are the building blocks of proteins.
- Amino acids are linked together by peptide bonds.
Structure of Proteins
- The structure of a protein consists of four levels.
Primary Structure
- The primary structure is the amino acid sequence.
Secondary Structure
