Proteins
Organic compounds, usually linear polymers, made of amino acids linked together by peptide
bonds.
Carbohydrates
Organic molecules consisting only of carbon, hydrogen and oxygen that serve as structural
components in cells and as energy sources
Catalyst

Exergonic
Reactions that release energy are called this
Anabolism
A general term for reactions that build larger molecules from smaller ones
Hydrolysis
The splitting of a molecule into smaller components by addition of water molecule
Condensation
A general term for reaction in which water is released
Fibrous Protein
