Carbohydrates, lipids, proteins, and nucleic acid
____ if the most common element and often acts as a filler in complex molecules
Hydrogen
Chains of hydrogen and carbon are called ____
Hydrocarbons
_____ are good vectors of energy transfer, bc their bonds are stable but not too stable
Hydrocarbons
Compounds that have the same numbers of atoms/elements, but different structures are called ____
Isomers
____ different in the covalent arrangement of their atoms
Structural Isomers
____ have the same covalent bonds, but have differing spatial arrangements due to the inflexibility of double bonds
Cis-Trans Isomers
_____ are isomers that are mirror images of one another
Enatiomers
_______ are often the portions directly involved in chemical reactions and vary considerably in their composition
Functional Groups
Biological macromolecules are long molecules made up of the same or similar building blocks called _____
Polymers
The individual blocks themselves that make up polymers are called ____
Monomers
Macromolecules are very often comprised of ____ and ____
