the subunits help to stabilize the overall structure. For example‚ insulin (a globular protein) has a combination of hydrogen bonds and disulfide bonds that cause it to be mostly clumped into a ball shape. Nucleic acids are the most important macromolecules for the continuity of life. They carry the genetic blueprint of a cell and carry instructions for the functioning of the cell. Dna And

Mazarei Food Microbiology April 22‚ 2011 Purpose: To test the pH level of many common household object by use of the juice from a red cabbage. Background: pH is the measure of the acidity or basicity of a solution. The pH scale ranges from 1 to 14 with 1 through 6 being acidic and 8 through 14 being basic; 7 is considered neutral. The use of the red cabbage‚ or red cabbage juice is because red cabbage can be used as an acid/base indicator. The pH level of foods is important to food microbiology

compounds also usually contain hydrogen atoms. Even though life is very complex‚ all large molecules that make up life are categorized into four large classes: lipids‚ protein‚ carbohydrates‚ and nucleic acids. These four molecules are known as macromolecules‚ due to their large size. Atoms have diverse characters that depend on the atoms electronic configuration. Carbons unique configuration allows it to form bonds with up to four other atoms‚ and gives carbon a covalent compactivity with many other

considered alive. These requirements are macromolecules‚ it needs to have metabolism‚ and be able to reproduce. If something has all of these things then it can be considered alive. The first requirement is that it has to have cells. Beings also need macromolecules because they need energy. The four macromolecules are carbohydrates‚ lipids‚ proteins‚ and nucleic acid. Macromolecules are used for energy. A great example of this is humans an their intake of macromolecules. For the average human‚ 55-65% of

In this lab activity students performed an experiment with the use of distilled water and baking soda solutions as control. The experimental controls are accuracy indicators of laboratory results. Thus‚ controls are important in a lab because the observation results are dependent on the controls. The experimental results can be determined to be valid when it is compared with the control solution. The higher the similarity between the results and the control solution‚ the more accurate the investigation
