Polar Molecule

A molecule with a slight negative charge on one end and a slight positive charge on the other, like water.

Cohesion

The attraction between the hydrogen of one water molecule and the oxygen of another.

Acids

Substances found below 7 on the pH scale.

Bases

Substances found above 7 on the pH scale.

Unique Properties of Water

High surface tension, high specific heat, cohesion, and less density when frozen.

Organic Molecule

A molecule that must contain carbon to be considered organic.

Carbon Electrons

Carbon has 4 electrons in its outermost energy level.

Dehydration Synthesis

The reaction that forms polymers from monomers.

Hydrolysis

The reaction that breaks down polymers into smaller monomers.

Carbohydrate Monomer

Monosaccharide, with examples like glucose and sucrose.

Lipids

Protein Monomer

Amino acids, which are 20 different types.

Nucleic Acids

Made of nucleotides (sugar, phosphate, base), including DNA and RNA.

Starch

The way plants store glucose.

Glycogen

The way animals store glucose.

R-group

The part of an amino acid that makes it unique from others.

Function of DNA

To store genetic information.

Reactants

The substances that get changed in a chemical reaction.

Products

The new substances formed in a chemical reaction.

Enzymes
