ORGANIC MOLECULES

POLYSACCHARIDES (CARBOHYDRATES)

• Carbohydrates consist of carbon, hydrogen, and oxygen and have a 1:2:1
• Functional group- hydroxyl
• Subunits- monosaccharides
• Polymer- polysaccarides
• Examples include: cellulose, chitin, gluctose and sucrose

POLYPEPTIDES (PROTEINS)

• Proteins consist of carbon, oxygen, hydrogen, and nitrogen
• Subunits- amino acids
• Polymer- polypeptides
• Examples include: chicken, steak, and ostrich
• Functional groups- carboxyl, amino

TRIGLYCERIDES (LIPIDS)

• Lipids are made up of carbon, hydrogen, and oxygen
• Lipids make up what we call fat. (Saturated/Unsaturated)
• Unsaturated- at least 1 double bond. Liquid at room temp. Ex. Cooking Oil
• Saturated- all single bonds. Solid at room temperature. Ex. Butter
• Functional group- carboxyl

NUCLEIC ACIDS (DNA/RNA)

• Nucleic acids consist of carbon, hydrogen, oxygen, nitrogen, and phosphorus
• Functional group- phosphate
• Subunits- nucleotides
• DNA- Deoxyribose Nucleic Acid
• RNA- Ribose Nucleic Acid
