Bio students study molecular structures

The students in Erica Everett’s honors biology class work in teams to further their understanding of molecules and assemble structural models of carbohydrate molecules.

Students received a worksheet/guide to help them examine molecules and construct their own structural formulas.  A molecular formula shows the amount and types of atoms, and a structural formula does the same while also shows the layout of the atoms in a given molecule.

Sophomores Jake Brugger and Spencer Feurbach assemble two models of monosaccharides, or single sugars.  Molecules of different monosaccharides have the same amount of carbon, hydrogen, and oxygen atoms, but they differ in their structural formulas.

After constructing their molecules, sophomores Tracy Blagden and Julia Prziek answer guiding questions on their worksheets.  The students studied the formulas of glucose, galactose, and fructose, which are all simple sugars found in various foods.  Credit: Lillian Schrafft for Manchester Essex Multimedia Online

Sophomores Santana Tosi and Hannah Soucy build models of disaccharides, or double sugars.   A disaccharide is formed when two monosaccharide molecules chemically join together.  Credit: Lillian Schrafft for Manchester Essex Multimedia Online

The students’  finished models are placed on display in the back of the classroom.  After assembling double sugars, the students constructed complex sugars, which are formed when many single sugars are joined together chemically.  Credit: Lillian Schrafft for Manchester Essex Multimedia Online
