Chemistry Flashcards
Attractions between atoms that hold atoms and molecules together.
Chemical Bonds
An interaction between a partially charged hydrogen atom and a partially negative atom with an unshared pair of electrons.
Hydrogen Bond
Subatomic particle with a neutral charge that is contained in the nucleus and has a mass of approximately 1 atomic mass unit.
Neutron
The sharing of the electrons.
Covalent Bonds
An attractive force generated by the interactions between ions of opposite charges. Attraction between a positive and negative ion.
Ionic Bond
A positively charged subatomic particle that is contained in the nucleus and has a mass of approximately 1 atomic mass unit.
Proton
The tendency of an atom to hold shared electrons more close to its nucleus.
Electronegativity
Negatively charged subatomic particle that occupies shells surrounding the nucleus and has a mass that is so small it is considered to be zero.
Electron
Small organic molecule with the structure of an amino group, a carboxylic acid group, and an “R” group, which are all bonded to a single central carbon atom.
Amino Acid
A type of lipid composed of glycerol and saturated fatty acids; typically solid at room temperature.
Fats
Hydrophobic or water fearing molecules do not interact with water and are characterized by a complete lack of electronegative atoms.
Hydrophobic
A small organic molecule that may bind chemically to other molecules to form a polymer.
Monomer
Any molecule that contains a carbon to hydrogen covalent bond.
Organic molecule
A carbonhydrate that consists of long chains of monosaccharides bonded together.
Polysaccharide
A type of lipid composed of a common carbon ring structure. Example includes testosterone and cholestrol.
Steroid
Relatively large molecule made by living organisms from smaller molecular building blocks.
Biological Macromolecules
A simple carbohydrate. This is the primary product of photosynthesis and the primary reactant of cellular respiration.
Glucose
Simple molecules not found in living things. They may contain carbon and hydrogen but not both.
Inorganic molecules
A simple sugar containing carbon, hydrogen, and oxygen atoms in a 1:2:1 ratio
Monosaccharide
A molecule consisting of a glycerol bonded to a phosphate group and two fatty acids.
Phospholipids
An organic macromolecule consisting of folded chains of amino acids
Proteins
Nonpolar lipids that form protective layers on plants and animals.
Waxes
The extracellular surface of the cell membrane is decorated with carbohydrate groups attached to lipids and proteins
Carbohydrates
Molecules that are water soluble
Hydrophilic
