This organic macromolecule is made of monomers called amino acids.
What are proteins?
A fatty acid in which the carbon chain have only single bonds filled with hydrogens.
What are saturated fats?
This organic compound includes fats and oils which are used for long-term energy and in the cell membrane.
What is a lipid?
The millions of organic compounds can be grouped into these four major types of compounds.
What are carbohydrates, lipids, proteins, and nucleic acids?
A fatty acid that contains double-bonded carbon atoms and tends to be liquid at room temperature.
What are unsaturated fats?
Reactions in organisms that break down molecules into smaller units and release energy.
What is exothermic?
Water shares its electrons unevenly between the oxygen and the hydrogens causing a partial charge. This makes it a _______________.
What is a polar molecule?
This is a process that changes some chemical substances into others.
What is a chemical reaction?
