Lab report carbohydrates proteins lipids

In the lipids test, petri dishes were used to split the crackers and lemonade power. Upper Saddle River, New Jersey: The lab was conducted by first checking the initial results with water and the indicator solutions then by doing the same procedures with the crackers and lemonade.

Sources and Uses of Carbohydrates, Lipids, Proteins, Vitamins, And Major Minerals

A ninth unknown carbohydrate will also be run through the tests with the known sugars. Plants store excess glucose in the form of starch, a polysaccharide composed of long chains of glucose. Daly Ralston Resource Center: Ketoses react more quickly than aldoses and thus the reaction time is a means of separation or detection.

A positive control contains the variable for which you are testing; it reacts positively and demonstrates the test's ability to detect what you expect. The glucose present in the solution reacts with the copper sulfate in the Benedict reagent and makes copper oxide that is an orange to red-brick precipitate.

By testing the samples for a particular organic compound proteins, lipids, or carbohydrates and simple sugars, the data collected can directly represent the compounds within the solution. When we tested the cracker, we found that it does contain simple sugars and starch, however it did not contain lipids or protein, which was expected.

Sugar needs to be decomposed into its components glucose and fructose then the glucose test would be positive but the starch test would still be negative. In DNA deoxyribose nucleic acid the sugar is a deoxyribose and the nitrogenous bases are adenine, guanine, cytosine and thymine.

Use the results of the known test reactions to identify macromolecules. Extensions and Reflections Extensions and connections: Color change is used to determine if the test is positive or negative, and deciding what color or shade the result is can vary from person to person.

The aim of the study was to analyse the insulin requirements of women with type 1 diabetes mellitus throughout pregnancy. We also hypothesized that if a saltine cracker is tested for proteins, lipids, and carbs, then the test will come back positive for starch through the iodine test.

Students will see that Sudan red with stain the fat molecules. This lesson can easily tight into a health and nutrition unit. Unsaturated fatty acids contain double bonds within the carbon chain, which results in a bend of the chain. Retrieved September 11, In the original lesson students rotated throught the three different stations with an adult facilitating each station.

Each organic compound has a specific role and function in our body. Finally, to test for starch, we put our item in a test tube and mixed in a drop of iodine. When we eat food, we take in the large biological molecules found in the food, including carbohydrates, proteins, lipids (such as fats), and nucleic acids (such as DNA), and use mobile-concrete-batching-plant.com O Scribd é o maior site social de leitura e publicação do mobile-concrete-batching-plant.com://mobile-concrete-batching-plant.com /biological-macromolecules-lab-report.

· Organic macromolecules in living organisms can be classified as either carbohydrates, proteins, lipids, or nucleic acids, among others.

These macromolecules are always made of smaller subunits. These macromolecules are always made of smaller mobile-concrete-batching-plant.com://mobile-concrete-batching-plant.com  ·  Examples of monosaccharides, disaccharides and polysaccharides. The roles of carbohydrates in animals and plants.

The table below outlines one of the many roles of glucose, lactose and glycogen in animals, and of fructose, sucrose and cellulose in mobile-concrete-batching-plant.com /mobile-concrete-batching-plant.com  · Carbohydrates can be characterized in a number of di erent ways based on the number of carbons (pentose, hexose), the functional group (aldose, ketose), formation of rings (furanose, pyranose), and isomers (D or L) and the number of monosaccharide units in the molecule (mono, di, and polysaccharides).
