(CGUHS) On Tuesday, November 05, Ms. Patun-og's Honors Biology performed a lab experiment on Biomolecules. Students used test indicators for lipids, proteins, and carbohydrates. For lipids, positive results indicated the presence of a translucent spot in the brown paper. For proteins, they used Biuret solution. Biuret is clear or light blue in the absence of protein, and changes to pink or blue-violet in the presence of protein. For carbohydrates (sugars), they used Benedict solution. Benedict solution changes from blue to green, yellow, or orange when heated if a monosaccharide is present. Students provided data of the results. Overall, students did a great job working collaboratively, following the scientific method, identifying lab equipment, and recording and analyzing data.
