7352165229What are the Organic Molecules?-Carbohydrates -Lipids -Nucleic Acids -Proteins0
7352165230What do all organic molecules containcarbon and hydrogen1
7352165231What is special about carbon?-Four valence electrons=four possible bonds -Can bond with itself with single, double or triple bonds -Can make long crazy branches or rings2
7352165232Functional Groupsspecific combinations of atoms that determine reactivity and polarity.3
7352165233Macromoleculesmade of repeating subunits.4
7352165234Subunit and Polymer of CARBOHYDRATESsubunit: monosaccharide polymer: disaccharide or polysaccharide5
7352165235Subunit and Polymer of LIPIDSsubunit: gycerol and fatty acids polymer: fat6
7352165236Subunit and Polymer of PROTEINSsubunit: amino acid polymer: polypeptide7
7352165237Subunit and Polymer of NUCLEIC ACIDSsubunit: nucleotide polymer: DNA or RNA8
7352165238Protein Monomers--> proteinamino acid -> peptide -> polypeptide -> protein9
7352165239Protein Description- a polypeptide that has folded into a particular shape, which is essential for its proper function - make up structure - hormones such as insulin - antibodies - ALL OF THE FUNCTIONS because of their 20 different amino groups10
7352165240Amino Acid Structure and BuildupAmino Group + amino acid + Hydrogen + carbon + R (variable functional group)11
7352165241Protein StructurePrimery structure: sequence of amino acids Secondary structure: hydrogen bonds between the amino acids cause the chain of amino acids to form alpha helixes and beta sheets. Tertiary Structure: the folding due to other chemical reactions and the bonding between R groups. Quaternary structure: multiple chains of amino acids interacting with each other.12
7352165242Carbohydrate Description- Made of Carbon, Hydrogen, and Oxygen in a 1:2:1 ratio - Energy source - Building material13
7352165243Monosaccharides- Always in rings - The hydroxyl groups makes them soluble in water14
7352165244Polysaccharides- A source of energy: starch for plants and glycogen for animals - Structure: cellulose in plants and, chitin in animals, and preptidoglycan in bacteria15
7352165245Glycogenthe polysaccharide energy source for animals16
7352165246Lipid GroupsTriglycerides Waxes Steroids Phospholipids17
7352165247Triglyceridessaturated (fats that are solid and come from animals) and unsaturated (fats that are liquid and come from plants) Made out of a gylcerol and 3 fatty acids.18
7352165248Waxesfats that are used in water retention by plants, structural purposes by bees, and ear canal protection and water proving by humans and some other animals.19
7352165249PhospholipidsMade of a polar head and non polar fatty acid tales. They form the plasma membranes of cells because the head faces the water (as it is polar) and the fatty acids face the inside of the cell. The kinks in the tale keep the plasma membrane fluid so that things and come and leave the cell.20
7352165250Steroids- They form 4 fused carbon rings that differ in their functional groups. - They make up components of animal cells - Cholesterol, testosterone, and estrogen21
7352165251Nucleic AcidsDNA (deoxyribonucleic acid) -genetic material -two strands connected by hydrogen bonds RNA (ribonucleic acid) -one strand -messenger ATP (adenosine triphosphate) -high energy molecule -two unstable phosphate bonds that are easily broken.22
7352165252Structure of a nucleotide-pentose sugar -phosphate grouop -nitrogenous base23
7352165253pHmeasure of hydrogen concentration24
7352165254Acidsrelease hydrogen ions high [H+] concentration25
7352165255Basestake up hydrogen ions or release hydroxyls. low [H+] concentration26
