Glucose Tap Water Essay Example for Free

Glucose Tap weewee Essay1. Monosaccharides and polysaccharides be two classes of Carbohydrates2. Long chains of amino acids even up up Proteins_ and contain the atom _Nitrogen which is unique to this macromolecule.3. Fats like triacylglycerols are the macromolecule ___lipids_____.4. You just reviewed type of carbohydrates. Glucose is a simple sugar called a monosaccharide , whereas amylum contains compound carbon chains and is a polysaccharide .5. Polysaccharides are formed by a dehydration synthesis reaction between monosaccharides. What does this mean? Water molecules are removed from the bond.6. For each of the following tests, please circle which substance would give a positive entrust a. Benedicts test glucose solicit water anele (lipid)) starch protein b. Starch test glucose tap water oil (lipid)) starch protein c. Sudan IV test glucose tap water oil (lipid)) starch protein d. Biuret test glucose tap water oil (lipid)) starch protein7. All proteins contain carbo n, hydrogen, oxygen and what other element? Nitrogen8. When one glycerol molecule covalently bonds via dehydration synthesis with third fatty acid molecules the resulting macromolecule is called a __lipid_________.9. What are the two general categories of carbohydrates? Starch and cellulose ID the test Sudan IV, Benedicts, Biuret, Starch10. The cloudy, orange color that shows a positive result for the __Benedicts____ test is due to simple sugars reducing cupric ions to cuprous ions which oxidize to form copper oxide.11. If a solution contains macromolecules that test positive for the Biuret test, light refracts from copper-containing ring to produce a violet color.12. The reagent used in the _Sudan IV__ test is soluble in lipid, but not in water. Adding ethanol to test solutions is necessary.Uses of Macromolecules13. Explain the contravention between lipids and carbohydrates with respect to energy use and storage. Lipids store energy as backup energy to be used when the carbohydra tes are all burnt up. Carbohydrates are less complex and thitherfore easier to break down than lipids. The body stores lipids as fat cells were carbohydrates are stored as sugars.14. Fully describe at least phoebe bird uses of proteins in the body.-Motion of cells depends on proteins-They catalyze reactions in cells-Transportation of material in body fluids is dependent on protein. -They form receptors for sending signals throughout the body.-Proteins are stored in heft tissues15. Fully describe the differences between DNA and RNA. RNA is responsible for transporting genetic code from the nucleus to the ribosomes. DNA stores the genetic code so it does not trigger and therefore can be safe in the nucleus. DNA contains the genetic instructions while RNA transports the proteins needed to create the genetic instructions. Without RNA there would not be any DNA.
