bioMOLECULES THE STUFF OF LIFE
Biomolecules Organic molecules made up of: • Carbon • Hydrogen • Nitrogen • Oxygen • and sometimes Phosphorus
LATIN 101 • Poly = Many • Mono = One • Hydro = Water (actually Greek) • Synthesis = to make or form • Lysis = loosen; break apart • Lipos = fat
Carbon compounds and cells • Life as we know it is carbon-based. • A carbon atom can form chemical bonds with other carbon atoms in long chains or rings.
Carbon compounds and cells • Carbon compounds in living things include: carbohydrates, proteins, lipids and nucleic acids.
ORGANIC compounds-COMPOUNDSTHAT CONTAIN THE ELEMENT CARBON 95% of all compounds are organic Example: Glucose C6H12O6
Polymers – large organic molecules made of smaller parts known as monomers (Building blocks of polymers)
CARBOHYDRATES • Carbohydrates are energy-rich compounds made from carbon, hydrogen, and oxygen (they store energy) • Cells use carbohydrates to get and store energy. • Carbohydrates add structure to plants (cellulose) • Carbohydrates are also called sugars or starches.
Carbohydrates • Plant cells store energy as starch. • Rice, potatoes, and wheat are plant starches.
LIPIDS • Lipids are made by cells to store energy for long periods of time. • Used to make membranes in cells. • Lipids include fats, oils, and waxes. Can you think of examples of lipids in plants or animals?
PROTEINS • Proteins are very large molecules made of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur. • Protein molecules are made of chains of smaller molecules called amino acids. • Control structure & metabolism of cells
NUCLEIC ACIDS • Nucleic acidsare compounds made of long, repeating chains called nucleotides. • DNA is a nucleic acid that contains the information cells need to make all of their proteins. DNA is the “blueprint” for living organisms.
DNA • Some scientists refer to DNA as the “blueprint” for life. What is a blueprint and why might scientists use this “analogy”?
