Introduction: In living things, organic compounds ar present. Most putting surface forage contains the just about abundant organic compounds of lipids, carbohydrates, and proteins. Lipids are utilise to store energy. They include fats oil colors and waxes. They contain mostly hydrogen and cytosine atoms. Carbohydrates are a main source of energy for most living things. Proteins are unity of the more diverse macromolecules. Proteins are made up of Nitrogen, carbon, hydrogen and oxygen. They are made up of hydrogen carbon and oxygen atoms. Some examples are starches and sugars. peerless can find out if a substance has one of these organic compounds by using an indicator, which changes color in the battlefront of a particular compound.

Purpose: To find the presence of organic compounds in common food for thoughts.

Hypothesis: If the food contains fats oils or waxes like vegetable oil and butter then the food pull up stakes contain lipids

If the food contains carbohydrates like potatoes then it will contain starches

If the food is winning like honey and apple juice then it contains sugars.

Eggs will contain protein.

Procedure:

1.         Divide a piece of brown piece of music bag into ten equal sections and in from each one section write one of the names of the food sample.

2.         In each section place a small drop of the food sample and wipe off any excess pieces of food.



assign it aside for 15 minutes.

3.         Hold the paper up to a bright light and check off any samples that tried positive for lipids.

4.         Place eight hear tubes on a test tube rack and label each with a wax crayon with one of the common food samples.

5.          call a graduated cylinder to transfer two mL of tap water in the test tube mark water. Use a wax crayon to mark the test tube at the level of...
