Which macromolecules were present in the unknown solution

Cholesterol is also the precursor for other steroids, such as testosterone and estrogen. Some vitamins, such as Vitamin D, are also classified as steroids. Proteins are polymers of amino acids. There are twenty naturally occurring amino acids, and each amino acid has a unique side-chain or R-group.

Amino acids are connected by peptide bonds to form protein polymers. This gives rise to different levels of structure for proteins. At this level, structures called alpha-helices and beta-sheets are visible. Proteins have numerous biological functions. The common types of proteins that are found in biological systems are enzymes, antibodies, transport proteins, regulatory proteins, and structural proteins.

Test samples: distilled water, glucose, starch, orange juice, regular soda, diet soda, unknown. Fill a beaker about halfway with water and bring it to a gentle boil on the hot plate.

Label tubes. Use a wax pencil to label the tubes with the test and sample ID; label at the volume markings listed below. Add 2 mL. Record the color in the table below. Label tubes Use a wax pencil to label the tubes with the test and sample ID; label at the volume markings listed below. Test samples: distilled water, vegetable oil, cream, and unknown.

Record the appearance of the bag where you placed the spots in the table below. Red dye concentrates in the top layer. Test samples: distilled water, starch, egg albumin, glucose, regular soft drink, unknown. Look back over the results for the unknown sample from each of the previous tests. Based on the data, what combination of macromolecules is present in the unknown mixture?

Which test could you use to distinguish between diet and regular soda? What would the test detect? Each test included a sample that was just water. These macromolecules could either be amino acids, proteins or nucleic acids.

They are responsible for the chemical changes and reactions that affects largely the cell and its composition. A macromolecule is a very large molecule, such as protein, commonly created by polymerization of smaller subunits monomers. They are typically composed of thousands or more atoms. These macromolecules might either be amino acids, proteins or nucleic acids. They are accountable for the chemical changes and reactions that moves largely the cell and its composition.

Take for example the cytoplasm of the cell where these organelles are settled. These simple organelles are composed of macromolecules which ignites and catalysis different functions that enables cells, in macro-perspective in motion and metabolism. In intestines for instance, metabolism occurs and breaking down parts of a food to simpler compounds that are used and these nutrients delivered throughout the body and again broken down by into smaller components.

Biology , Which macromolecules were present in the unknown solution? Answers: 1. Answer from: esme Answer from: hard Answer from: liltam Iodine test is commonly used for identification starch. Sudan III Test for identification of lipids. In the milk?

Biuret test for detection of protein Benedicts test for carbohydrates Sudan III test for detection of fats. So positive results for all above will indicate the presence of milk. What was the role of the water test tube in each phase? Answer from: joseph Answer from: Nalolivares. Answer from: zookieblu. Lipids and proteins. Lipids are macromolecules which provide insulation. A macromolecule is a large molecule. There are four groups of macromolecules: carbohydrates, proteins, nucleic acids and lipids.

Lipids consist of glycerol and fatty acids and are constructed from fats, oils, waxes, phospholipids and steroids.

A lipid's function is to insulate the body and provide warmth in cold conditions. It can be concluded that a person with very little body fat gets very cold easily and a person with a lot of body fat gets very warm very quickly.

The poli How was the outcome of the Munich Agreement similar to the outcome of Adolf Hitler's nonaggression agreement with Stalin? The fundamental purpose of Neo-Confucianism was Select one : a to diminish the disproportionate influence of the aristocracy. What we conclude from the research on categorization is that the approach to categorization works best for small categories e. What was President McKinley's primary purpose in giving this speech? An author wants to show that a character has a deep desire to explore the world.

What object would represent this wish? Open a general journal for the City of Monroe Community Foundation Trust Fund and record the following transactions for the year ending December 31, Summer Tan, Inc. Management believes the earnings Why did the author use a definition pattern in this passage?
