INTRODUCTION:

Any occurrence containing lipids can indeed be discerned using just brown paper. Water would be assimilated by the paper, but oil can not, and an oily patch will appear. Users will identify the presence of organic chemicals such as fats in a variety of liquids in this experiment which will be tested. (Study.com date unknown). Lipid testing is done with brown paper bags. Throughout the existence of lipids, the paper bag appears translucent (means allowing light passing through). (Macromolecules date unknown). The objective of this laboratory is to use a range of compounds to check for the existence of a certain macromolecule.

STATEMENT OF THE PROBLEM:

• How does the brown paper bag distinguish if a sample contains lipids?

• What is the main difference between using brown paper and other colored paper when it comes to detecting a lipid?

• What is the overall observation for this experimentation?

MATERIALS AND QUANTITIES:

TABLE 1: Materials which are required for the experiment.

All the necessary materials for the laboratory experiment are easily accessible in the researcher's house. Essentially, the supplies and equipment involved are not difficult to get or use because the components and supplies are widely available, making experiment accessible to anybody interested in giving it a try.

TABLE 1.2: The actual preparation of the materials.

Before conducting the experiment, the researcher put on an apron as well as gloves to keep contaminants and stains from leaving the lab. Secondly, the researchers gathered the five small containers that would be used to store the test's materials. The five main ingredients, sunflower oil, coconut oil, corn syrup, canola oil, and vinegar were each measured within 2 cc using a syringe. Furthermore, to cut the brown paper into five squares, the researcher used a ruler that is perfect for the exact same measurement that is more likely needed for the experimentation of testing the lipids. Additionally, the researcher used a pen to mark each paper within their specific substance. The researcher also used the tissues as an optional to wipe all the discarded solution during the experiment. Lastly, the researcher observes the whole experiment and examines the changes on each of the said samples.

DISCUSSION:

Nuts, oils, butter, and some poultry include lipids, which are oily substances found in some diets. Other foods, such as the majority of fruits and vegetables, are fat-free. Fat is an important part of a balanced diet. Fat aids in the regular growth and development of the body. Fats provide energy to the body and aid in the absorption of certain vitamins. (Davis 2021). The objective of this experiment is to prove that certain kinds of paper (such as a piece of a brown paper bag) readily absorb lipids and can be used to test for the presence of lipids. Next, the bag is held up to a light source. If a translucent mark is observed, the material contains lipids. The brown paper bag is more preferable than other colored paper due to the fact that it can easily detect the presence of lipids within the paper.

CONCLUSION:

Fatty oils are lipids, which are made up of molecules that do not dissolve in water. These are essential for our body's operations because they transport vitamins, assist in the formation of cell walls, and store energy for lengthy periods of time. Eating too much fat can be dangerous, but a healthy diet will include a sensible amount. (HomeScienceTool date unknown). In conclusion, the said substances stained the brown paper and the stain was see-through – this type of stain on the brown paper is called a translucent stain. Although some of the samples are detected presently, there is one sample stained but that does not mean that the lipid is detected because vinegar is an acetic acid.
