MOLECULES OF LIFE LIPIDS (FATS) NUCLEIC ACIDS CARBOHYDRATES PROTEINS What elements/ molecules is it made of? What elements/ molecules is it made of? What elements/ molecules is it made of? What elements/ molecules is it made of? C, H, O C, H O C, H, O, N, P C, H, O, N, P, S Identify the building blocks it is made of. Identify the building blocks it is made of. Identify the building blocks it is made of. Identify the building blocks it is made of. Monosaccharides- Glucose, Fructose, Galactose Glycerol & Fatty Acids Nucleotides(Sugar + Phosphate + Base ) ( Bases = A, T, G, C, U ) Amino Acids ( 20 of them) (Amino group + carboxyl group + Side group) What are they found in? (examples) What are they found in? (examples) What are they found in? (examples) What are they found in? (examples) DisaccharidesSucrose- table sugar Lactose- milk Triglycerides- Foods DNA Hemoglobin- In blood Phospholipids- structure of cell membranes RNA Photosystems- In chloroplasts ATP ENZYMES - Everywhere PolysaccharidesWaxes Starch – Pasta, potatoes, corn Chitin- Animal shells Cellulose- Plant cell walls (wood) Oils What is their purpose or functions? What is their purpose or functions? What is their purpose or functions? What is their purpose or functions? Monosaccharides- Immediate energy through respiration and fermentation Triglycerides- STORAGE of Energy DNA- Contains the instructions for life in its genetic code of bases Phospholipids- Water resistant barrier (in cells) RNA – Contains a COPY of the instructions for life from the DNA genetic code of bases Enzymes- Carry out cellular reactions like digestion (amylase and protease), steps of respiration and photosynthesis (photosystems) Amylase- Salive Protease- Stomach PolysaccharidesStarch- Sugar storage Chitin- Protection and strength Cellulose- Protection and structure Waxes- Protective coatings (water proof) Oils- water resistant lubricants and storage of energy ATP- Contains high energy bond used to power cellular functions Hemoglobin- Transports oxygen in the blood Make Hormones- Signals to cells Fight disease in immune system Growth & Repair - Build important structure- hair, finger nails, bones MOLECULES OF LIFE
