Protein Shape

• Cells link amino acid monomers together by dehydration reactions.
• Peptide bond is the bond that joins adjacent amino acids.
• Polypeptide is the resulting long chain of amino acids.
• The difference between a polypeptide and a protein is to be functional, the long fiber must be precisely knit into a specific shape.
• Each protein has a unique linear sequence of amino acids.
• The amino acid sequence determines the protein’s three-dimensional structure, saying its specific function. Even a slight change in the sequence can affect a protein’s ability to function.
• For all proteins, structure and function are interrelated.
• A protein’s shape is sensitive to the environment.
• An unfavorable change in temperature, pH, or some other factor can cause a protein to unravel.
• What determines a protein’s amino acid sequence? It’s specified by a gene.
