lesson 6 unit 2 a
How many electrons does carbon lack in its outer shell?
4
polymer
A chemical compound in which each molecule is made up of two or more simpler molecules strung together.
lipid
A group of organic compounds including fats, steroids, and phospholipids.
protein
A large complex organic molecule consisting of a large number of amino acids linked together by peptide bonds.
polymerization
A reaction in which two or more molecules unite, forming a more complex molecule.
nucleic acid
A sequence of sugars, phosphates and nitrogenous organic bases: DNA and RNA.
carbohydrate
A sugar or polymer of sugar; contains the elements carbon, hydrogen, and oxygen.
Carbon is ideally suited to form ionic bonds.
False
Many elements bond to carbon by exchanging electrons.
False
carbohydrate
a polymer of sugar
RNA
an acid located in the cell nucleus
When compounds which are formed from ionic bonds decompose, the products:
are usually ions of the original elements
amino acid
basic units of proteins
Why can carbon bond to many elements simultaneously?
because it is capable of forming multiple covalent bonds
Large organic molecules which are synthesized from multiple identical subunits are:
carbohydrates polymers proteins nucleic acids
hydrolysis
decomposition using water
What happens when organic molecules decompose?
energy is released
