The FDA's The FDA's stance is that GM foods are substantially eq uivalent to unmodified, "natural" foods, and Perform tests to detect the presence of carbohydrates, lipids, proteins, and nucleic acids 2. Benedictâs Test: Test unknown for monosaccharides. . To detect the presence of simple carbohydrates in a solution. You can do it at home or school using the readily available equipment. Typically, molecule names ending in "âose" will be carbohydrates. Which food contains carbohydrates, proteins, and fats? There are certain tests used to detect macromolecules and other molecules in food. Biology is brought to you with support from the Amgen Foundation. The four biomolecules specific to life on Earth are carbohydrates, such as sugars and starch; proteins, such as enzymes and hormones; lipids, such as triglycerides; and nucleic acids, including DNA and â¦ The other answers each belong to a different category of macromolecule: cholesterol is a lipid, miRNA is a nucleic acid, and lipase is a protein. Source for information on Biochemical Analysis Techniques: World of Microbiology and Immunology dictionary. Explanation: . Use biochemical tests to identify an unknown compound Introduction Organic molecules are those primarily made up of carbon, hydrogen and oxygen.
