Hypothesis: If the mystery food is tofu, then it will react with the reagent that indicates the presence of a protein because tofu is primarily protein. Based on the data, was Zack, who ate the tofu, guilty of leaving a mess in the classroom? Justify your answer.

You have just sequenced a new protein found in mice and observe that sulfur-containing cysteine residues occur at regular intervals. what is the significance of this finding? it will be important to include cysteine in the diet of the mice. cysteine residues are required for the formation of α helices and β pleated sheets. cysteine residues are involved in disulfide bridges that form tertiary structure. cysteine causes bends, or angles, to occur in the tertiary structure of proteins.
