THE PROCESS OF SCIENCE 13. A food manufacturer is advertising a new cake mix as fat-free. at the FDA are testing the product to see if it truly lacks fat. the cake mix yields glucose, fructose, glycerol, a number o and several kinds of molecules with long hydrocarbon chal analysis shows that most of the hydrocarbon chains have a ca group at one end. What would you tell the food manufacturer Hydrolysis of amino acids ns. Further were a spokesperson for the FDA? f you 14. Imagine that you have produced several versions of lactase, each of which differs from normal lactase by a single amino acid. Describe a that could indirectly determine which of the versions significantly alter the three-dimensional shape of the protein. test BIOLOGY AND SOCIETY 5. Some amateur and professional athletes take anabolic steroids to help them build strength ("bulk up"). The health risks of this practice are extensively documented. Apart from these health issues, what is thlntor uring chemicals to enhanc L il uf

Explanation / Answer

We know that enzymes are proteins and proteins are only functional in their three dimensional configuration. Lactase is also an enzyme. So,any change in the aminoacid would bring a change in the three dimensional shape of lactase that would effect its enzymatic function. A change in single aminoacid would also alter the three dimensional structure of the different versions of the lactase and this would also effect its enzymatic activity. We can go for an enzyme assay to test for the enzymatic activity of each of the different versions of lactase to find out in which aminoacid version ,the enzymatic activity is least which means that version of lactase has significant alteration in its three dimensional shape. The versions that alter the three dimensional shape of the protein would show none/least enzymatic activity oe we can say no enzyme activity means significant change in three dimensional shape of lactase.
