Organic Compounds

Biology 9th grade

QuestionAnswer
What are macromolecules also known as Polymers
If all the macromolecules are made mainly of the elements CHO, how are they different? They have different ratios
Name two ways that your body uses carbohydrates. Energy and structure support
What are the subunits called that make up carbohydrates? Monosaccharides
What is the ratio of C, H, and O in monosaccharides? 1:2:1
Name three monosaccarides. Glucose, fructose and galactose
What are monosaccharides? Simple, single sugars
What are disaccharides and give an example Double sugars. Maltose and sucrose
What are polysaccharides?, Name three Long chains of sugars. Starch, cellulose, glycogen, chitin
What are the four main classes of organic compounds? Carbohydrates, lipids, proteins, and nucleic acids
What are polymers or macromolecules? Organic compounds that are essential to the proper functioning of all living things
What are organic compounds? Compounds that contain carbon.
Why does carbon's structure allow it to be such a great building block? It's structure allows it to make four covalent bonds with other molecules.
What is the type of reaction in which monomers join to make polymers called? Dehydration synthesis
What is the type of reaction in which polymers are broken apart into monomers called? Hydrolysis
What elements carbohydrates made of? carbon, hydrogen and oxygen Atoms
What test is used to identify a monosaccharide and what is the result? Benedicts test. Liquid changes from blue to orange when heated.
What test is used to identify a disaccharide and what is the result? Process of elimination. If the tests are negative for monosaccharides AND polyccharides, then it is a disaccharide.
What test is used to identify a polysaccharide and what is the result? Iodine test. The iodine will change from yellow/brown to purple/black.
What elements are lipids made of? carbon, hydrogen and oxygen atoms
What elements are nucleic acids made of? carbon, hydrogen, nitrogen, oxygen and phosphorus atoms
What elements are proteins made of? carbon, hydrogen, oxygen and nitrogen atoms.
What is an example of a polysccharide? Pasta and bread
What is an example of a disaccharide? table sugar
What is an example of a monosaccharide? fructose
What is the monomer of a carbohydrate? A simple sugar called a monosaccharide.
What are the monomers of lipids? Fatty acids and glycerol.
Name some examples of lipids. Fats, oils, waxes and steroids
What is the function of lipids? Storing energy(oils and fats), protective coverings(wax)
Are lipids soluble in water? No
What two tests can be used to determine the presence of lipids? Translucence test and solubility test
Describe the translucence test on lipids. If a lipid is present, a paper touching a the lipid will turn translucent.
Descibe the solubility test on lipids. Lipids are hydrophobic so if a substance doesn't mix with water, a lipid is present.
Define Hydrophobic. Does not mix with water
