Final answer:
Bread contains both starch and lipids. When testing food for sugar, use a test strip that changes color in the presence of glucose.
Step-by-step explanation:
Bread is a food that contains both starch and lipids. Starch is a complex carbohydrate that is found in foods like bread, pasta, and potatoes. Lipids, on the other hand, are a type of fat that can be found in foods like butter, oils, and fatty meats.
When testing food for the presence of sugar, one safe method is to use a test strip that changes color in the presence of glucose. The test strip is dipped into a solution made from the food being tested, and if glucose is present, the strip will change color.
One safety precaution to take when testing food for the presence of lipids is to handle any chemicals used with care. Some lipid tests may involve the use of solvents or reagents that can be hazardous if not used properly. It is important to follow all safety guidelines and wear appropriate protective equipment when conducting lipid tests.
