TermDefinition
Monomer Basic units that repeats over and over in organic compounds
Polymer A substance that has a molecular structure consisting chiefly or entirely of a large number of similar units bonded together, e.g., many synthetic organic materials used as plastics and resins.
What are the 4 classes of macro-molecules ? Carbohydrates, Lipids, Protein, and Nucleic acid.
What elements are Proteins made up of? Carbon, Hydrogen, Oxygen, and Nitrogen
What elements make up Nucleic Acids (DNA & RNA)? Carbon, Hydrogen, Oxygen, Nitrogen, and Phosphorous
What are three main elements that the body needs to function? Sulfur, Calcium, and Potassium
What 4 elements make up 95% of the human body? Carbon, Hydrogen, Nitrogen, and Oxygen
What are macro-molecules ? A very large molecule, such as protein, commonly created by the polymerization of smaller subunits (monomers). They are typically composed of thousands of atoms or more.
Polymerization A process of reacting monomer molecules together in a chemical reaction to form polymer chains
Whats elements make up Carbohydrates and lipids? Carbon, Hydrogen, and Oxygen
What are organic compounds usually made up of? Carbon
Compounds can be placed in which two groups? Organic and Non-organic
What are the main functions of carbohydrates? Quick Energy and Storage
What is the monomer of Carbohydrates? Monosaccharide
What is the ratio of Hydrogen to oxygen in Carbohydrates? 2:1
Types of Carbohydrates (amounts) One sugar (C6 H12 06 Monosaccharide) Two Sugars (C12 H22 011 Diaccharide) Many sugars (polysaccharide)
What is a polysaccharide? 3 or more repeating units (long chains of sugar)
What are some examples of polysaccharide? Cellulose, Chitin, Glycogen

What are the functions of lipids Storage, Energy reserves, and cell membrane
What are some special characteristics of lipids - Insoluble in water - Shaped like an elongated E
What are the monomers of Proteins? Amino acids
What are the functions for Proteins - Basic building blocks of living material -Hair, Muscles, Fingernails -Enzymes
What makes up cell membranes? Phospholipids
What is a triglyceride made up of glycerol and three fatty acids
