Nucleic Acids Make two columns on the front. Biomolecule On the inside, label the flaps Building Block Characteristics Building Block and the uncut side Characteristics. O n B a c k Example: On the back, put the word Examples at the top. BIOMOLECULE CARBOHYDRATES Building Block MONOSACCHARIDES (simple sugars) EX: glucose or fructose CHARACTERISTICS *Used by cells to provide energy (QUICK ENERGY) Can form long chains called polysaccharides EXAMPLES *Food SourcesPotatoes, Pasta, Sugars In PLANTS: cellulose makes cell walls and starch stores food. In ANIMALS: glycogen is stored in the liver BIOMOLECULE LIPIDS Building Block Fatty Acids and Glycerol www.chemistryland.com/ElementarySchool/BuildingBlocks/ BuildingOrganic.htm CHARACTERISTICS *Fats are used for storage of energy (LONG term energy) & insulation 2Types: • Saturated Fats ex: lard and butter • Unsaturated Fats: ex: corn oil EXAMPLES In animals: Fats, Oils and Cholesterol In cell membranes: Phospholipids *Food Sources- Butter, Oils, Lard BIOMOLECULE PROTEIN Building Block Amino Acids LBNL Image Library -- Collection BERKELEY CHARACTERISTICS *Used to build structures for the body; carry out cell metabolism Proteins come in variety of shapes and sizes determining its individualized function EXAMPLES Meat, Eggs, Antibodies, and Enzymes *Food Sources- Milk, Eggs, Meat, Fish BIOMOLECULE NUCLEIC ACIDS Building Block Nucleotides CHARACTERISTICS *Store genetic information *Transmit genetic information to offspring *Produce proteins EXAMPLES RNA- single strand of nucleotides DNA- double stranded (double helix); genetic blueprint to life Remember: “CARBS ARE QUICK!” “LIPIDS ARE LONG!” “PROTEINS BUILD STRUCTURES!” CLOSING QUESTIONS: 1. Which food label would be best for a person wanting to add muscle tissue?_ Why? 2. Which food label would be best for a person that needed to gain adipose tissue (fat)? ___ Why? 3. Which food label would be best for a person that needs to store quick energy?__ Why?
