1. The color result is light brown.
2. A positive Biuret test indicates the presence of proteins in the filtrate. Biuret is used to test for proteins. It is a light blue color and changes to purple in the presence of protein, a polymer made of amino acids. It will not change color when only amino acids are present.
3. What type of molecules present in the suspension is hydrolyzed by the mild acid treatment?
4. The products of hydrolysis are peptones, peptides, and amino acids.
Purine Analysis
5. After the addition of silver nitrate, a dirty white solution with brown layer on top was produced.
6. Yeast, especially brewer's yeast, contains high levels of purines.
Ribose Analysis
7. After boiling, a brown solution was produced.
8. ----------------------------------------------------------------------------------------------------------
9. The result with 0.1% Glucose was a flesh-colored solution.
10. Ribose is one of the many vital carbohydrates necessary for our bodies to make ATP (adenosine triphosphate), which is the energy source used by our cells.
Phosphate Analysis
11. After heating, a cloudy white solution with white precipitate was the result.
12. Phosphorus forms a wide range of sulfides, where phosphorus can be P(V), P(III) or other oxidation states. Most famous is the three-fold symmetric P4S3 used in strike-anywhere matches. P4S10and P4O10 has analogous structures.
13. ATP, or Adenosine Triphosphate, is a molecule found in all living organisms.
14. ATP is important in the body because it is the main immediate source of usable energy for the activities of the cells.

ATP (adenosine triphosphate) is vital to living organisms. It acts as a short-term store of energy in a cell, carrying it from where it is synthesised (e.g. the mitochondria) to where it is needed for biological processes. It is well suited to this job for the following reasons: it is small and soluble (and so can be easily transported around a cell); it is easily broken down to release energy; it can transfer energy to other molecules; and it cannot leave the cell. All of these facts mean that ATP is always available to the cell as an immediate source of energy.…

Adenosine triphosphate (ATP) is a multifunctional nucleotide used in cells as a coenzyme. It is often called the "molecular unit of currency" of energy transfer. ATP transports chemical energy within cells for metabolism. It is produced by photo-phosphorylation and cellular respiration and used by enzymes and structural proteins in many cellular processes, including active transport, respiration, and cell division. One molecule of ATP contains three phosphate groups, and it is produced by ATP synthase from inorganic phosphate and adenosine diphosphate (ADP). ATP is used is many organisms and also in different ways. Below are a few ways in which ATP is used.…

The first, and the most valuable of all is Adenosine Tri phosphate, or simply, ATP, which is the immediate usable form of chemical energy for muscular activity. This is one of the most important of the "energy rich" compounds that is stored in all cells, particularly muscle cells. All forms of chemical energy available from the food we eat must eventually be transferred into ATP before the muscle cell can utilize them…
