The secondary structure of a protein consists of a single long beta sheet. The outer edges of the beta sheet are composed of serine and proline amino acids. Describe the effect changing all the serine and proline amino acids to glycine would have on the secondary structure of the beta sheet. Also, predict the effect this change would have on the function of the protein in an aqueous environment.

poor water quality affects most estuarine organisms, including commercially important fish and shellfish. the pollutants that have the greatest impact on the health of estuaries include toxic substances like chemicals and heavy metals, nutrient pollution (or eutrophication), and pathogens such as bacteria or viruses.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
