Document Summary

All are: complex carbohydrates, composed solely of glucose molecules, easily digested by animals, polysaccharides, found in plants, except glycogen, which is found in animals. The major cellular macromolecules include: proteins, lipids, amino acids, and carbohydrates, proteins, amino acids, lipids and nucleic acids, proteins, nucleic acids, carbohydrates and fatty acids, proteins, nucleotides, carbohydrates and lipids, proteins, nucleic acids, carbohydrates and lipids. A tca solution was added to a well-ground sand-yeast mixture. Then the sand was allowed to settle (p-1) and the liquid portion (s-1) was removed and then centrifuged to form a pellet (p-2) and a supernatant (s-2). Re- suspended p-2 was boiled and then centrifuged to form a pellet (p-3) and a supernatant (s-3). Cold ethanol was added to s-3 forming a suspension that was centrifuged to form a pellet (p-4) and supernatant (s-4). P-4 was re-suspended in sulphuric acid and half of this solution was transferred into glass tube and boiled for 30-60 minutes (s-5).

Charts and tables are tools we use in science to break down information analytically and present data in an organized manner. It is a beneficial strategy for learning about and organizing scientific material, which we will be using often in this class. Make sure that you are detailed, thorough, and specific in your responses. Explain yourself clearly. Do not list a word or brief phrase without explaining what it means. For example, if you list diabetes for carbohydrates, make sure you explain how carbs are associated with diabetes. Don't leave the reader to make that connection for you. Also, make sure you provide APA-style references for each of your so

When two of these carbohydrate monomers are bonded together what "class" of carbohydrate is formed? What are the types of this "class"? What is the source (food) for each of these?

When three or more of these monomers are bonded together they form which "class" of carbohydrate? Which one of these stores excess carbs in animals (mainly in the liver)? Which one stores excess carbs in plants?
