Polymer

• Molecule made of many monomers bonded together

• Also known as a Macromolecule

Monomer

• molecule that can bond to other similar molecules to form a larger molecule

Macromolecule

• A polymer with a high molecular mass; four groups within living things: carbohydrates, lipids, protein, nucleic acids

Carbohydrates• A macromolecule that contains

atoms of carbon, hydrogen, and oxygen in 1:2:1 ratio and serves as a major source of energy for living things

Protein

• A macromolecule that contains carbon, hydrogen, oxygen and nitrogen; performs a variety of structural and regulatory functions for cells

Peptide Bond

• Type of bond connecting two amino acids to form a protein

Lipids

• hydrophobic macromolecule consisting of a long chain of carbon and hydrogen atoms

Base

• any compound that increases the number of hydroxide ions when dissolved in water; falls above 7 on the pH scale

Acid

• compound that forms hydrogen ions (H+) in solution; falls below 7 on the pH scale

Dehydration Synthesis

• a chemical reaction in which two or more molecules combine to produce water or another simple molecule

Hydrolysis

Catalyst

• A substance that enables a chemical reaction to proceed at a faster rate by lowering activation energy

Enzyme

• A protein that increases the rate of a chemical reaction without being changed by the reaction; organic catalyst

Nucleotide

• Monomer used to build nucleic acids (5 types)

Nucleic Acid

• A biological macromolecule (DNA or RNA) composed of carbon, hydrogen, oxygen, nitrogen and phosphorus that stores genetic information
