Substances made up entirely of one kind of atom that cannot be broken down into any other simpler substance.
What are the types of chemical bonds and their definitions?
Covalent bonds: atoms that share electrons
Ionic bonds: the force of attraction between 2 ions
Hydrgen bonds: a "weak" bond between Hydrogen and another atom
What is released when a bond is broken?
Energy-engery is present in bonds to help hold them together
All organisms are made of organic compounds. All organic compounds MUST contain the elements carbon and hydrogen. They may also include other elements.
When two monosaccharides can be chemically joined together to form a larger molecules-literally means "double sweet"
When an organism combines at least 2 smaller molecules together to form a more complex molecules and water molecules are produced
What does your body use proteins for?
Body repair, replacement, and growth of body tissues and make hormones, antibodies, and enzymes
When simple sugars, or monosaccharides, combine together by dehydration synthesis to form long chains of molecules (comlex sugars)
Why must food be broken down into smaller, molecular sized particles?
So that is can be absorbed into our blood stream and body cells
What 2 monosarccharides join together by dehydration synthesis to form a sucrose molecule?
Glucose and fructose
Is it chemically correct to say that a protein is a polymer? Explain why.
Yes because proteins are repeating amino acids.
What contains more chemical bonds per molecule, a molecule of fat or a molecule of a monosaccharide?
A fat molecule because lipids are bigger molecules that have longer chains of fatty acids and they have more chemical bonds
When one glycerol and three fatty acids join together, what forms? During this dehyrdation synthesis, how many water molecules are formed?
Lipids are formed
3 water molecules are formed
What is the name of the organic molecules that can be chemically bonded together to form a polysaccharide?
Simple sugars (monosaccharides)
What is the name of the 2 organic molecules that are chemically bonded together to form a molecule lipid?
Glycerol and fatty acids
How many protons, neutrons and electrons are on a carbon atom?
6 protons, 6 neutrons, and 6 electrons
What are the 3 parts that make up lipids?
2. a long chain of carbon atoms bonded to hydrogen atoms
3. Carboxyl Group
One or more carbon to carbon bonds are double or triple bonds. Usually are liquid oils at room temperature
In what ways can you tell the difference bwtween an organic compound and an inorganic compound?
Organic compunds always have Carbon and Hydrogen
What four elements are most often found in organic compounds?
Carbon, Hydrogen, Oxygen, Nitrogen (CHON)
