Food Molecules Name: ______________________ Part 1: Identification of Molecules For each of the following organic structures, determine whether the material fits in the category of carbohydrate, fat or protein. In addition, identify what kind of molecule it is within the category. For instance, in the fat category, is it a saturated, monounsaturated, polyunsaturated, cis or trans fat. 1) carbohydrate, polysaccharide 2) protein, amino acid 3) carb, monosaccharide 4) carb, monosaccharide 5) saturated fat 6) protein, polypeptide 7) carbohydrate, disaccharide 8) trans monounsaturated fat 9) trans, polyunsaturated fat 10) cis monounsaturated fat Part 2: Fill in the following table. Substance Functional group(s) carbohydrate -OH Calories/gram Common examples 4 Cal/g Sugar, syrup, starches Monomer/Polymer Name Monosaccharide/ polysaccharide fat -COOH 9 Cal/g Oils, butter, meats NA protein -COOH and -NH2 4 Cal/g Meats, eggs, cheese Amino acid/ protein Part 3: Compare/Contrast For the following grouping of words, describe how the terms are similar and how they are different. 10) saturated fat, monounsaturated fat, polyunsaturated fat • • All are fats Saturated fats have no double bonds, monounsaturated fats have one double bond and polyunsaturated fats have multiple double bonds. 11) protein, polysaccharide • • Both are polymers Proteins are polymerized amino acids, while polysaccharides are polymerized monosaccharides 12) trans fat, cis fat • • Both are unsaturated fats Trans fats have the hydrogens on either side of the double bond on opposite sides, while cis fats have the hydrogens on either side of the double bond on the same side. 13) ADP, ATP • • Both are biomolecules inside of cells that are used to store energy for the cell. ADP has two phosphates attached to the adenosine, while ATP has three phosphates attached to the adenosine in high energy bonds.
