Bellringer We will be going over your Atoms, Ions, Molecules and Properties of Water Quiz today as the warm-up.
2
Carbon Chemistry
3
Learning Targets Describe why carbon atoms form the basis of organic molecules and the formation of organic monomers and polymers. Explain the basic structure of carbohydrates, the 3 main types of carbohydrates and their basic functions. Explain the basic structure of lipids, the 2 main types of lipids and their basic functions. Explain the basic structure of proteins and discuss the role of enzymes in chemical reactions. Explain the basic structure of nucleic acids, the 2 main types of nucleic acids and their basic function.
4
Carbon Carbon atoms have four electrons in their outer shell that can form strong covalent bonds. Carbon can also bond to other carbon atoms making unlimited chains with single, double or triple bonds. This allows carbon to form millions of different types of molecules. And make up the carbon backbone for our macromolecules.
6
Macromolecules Macromolecules are giant molecules formed by carbon joining with other carbon atoms and other elements by covalent bonds Some macromolecules are POLYMERS Polymers are formed when monomers (smaller units) join to form polymers (larger units) by covalent bonds. mono – one poly - many
9
Carbohydrates Main source of energy. Found in a ratio of (1:2:1)
1 Carbon : 2 Hydrogen :1 Oxygen Monomers: Monosaccharides: a single simple sugar molecule Ex. Glucose, fructose, galactose Disaccharides: two monosaccharides put together Ex. Lactose, sucrose, maltose Polymers: Polysaccharides: 3 or more monosaccharides put together Ex. Cellulose (make up plant cell walls), glycogen (stored in animal muscle), Starch (made and stored by plants)
12
Lipids Primary function to store energy Lipids are macromolecules
however, they are NOT polymers Types of lipids Triglycerides: found in solid state and liquid state as oil. Contain glycerol and 3 fatty acid chains Phospholipids: found in cell membranes Waxes: found in beehives Steroids (cholesterol): hormones, provide strength for cell membrane, made of fused rings of Carbon.
13
Benefits of Fats (Lipids)
Stored Energy Insulation Protection Buoyancy
15
Triglycerides: Saturated vs. Unsaturated Fatty Acids
Triglycerides: Saturated vs. Unsaturated Fatty Acids Saturated Fatty Acids: maximum number of H+ atoms used: the BAD BOYS!!! Unsaturated: contain at least 1 C=C bond (double carbon bond), liquid at room temperature.
18
Nucleic Acids Nucleic Acids are polymers Monomers: nucleotides
made up of hydrogen, oxygen, nitrogen, carbon, and phosphorus. Examples: DNA (located in the nucleus of the cell) and RNA Function: The molecules of genetic information…heredity and protein synthesis Monomers: nucleotides 5 carbon sugars with a phosphate and a nitrogen base. ATP is a nucleotide that is made up of 3 phosphates and stores energy.
20
Proteins Proteins are polymers Monomers: amino acids.
Made of nitrogen + carbon + hydrogen + oxygen. Monomers: amino acids. There are more than 20 different amino acids in nature. Amino Acids are different from each other because of their side group, also called R-group.
23
Functions of Proteins Control reactions Regulate cell function
Form bones and muscle Fight disease Transport substances
24
Protein Structure Proteins are joined together by peptide bonds
Three major shapes of proteins: Primary: sequence of amino acids Secondary: 3-dimensional folds Tertiary: globs Quaternary: interactions between globs
25
Protein Structure Talk it over
What do these pictures have to do with protein structure?
