5910106831Organic CompoundsContains carbon (C) bonded with other elements, especially C, O, H, N Biologically "living" things0
5910107022Inorganic CompoundsEverything else, ex. H2O, O21
5910109251WaterInorganic, Chemical structure dictates properties and biological functions Properties of _____: Polar molecule; -overall neutral but slight charge end to end -dissolves other molecules, therefore an effective solvent2
5910114326AdhesionAttractive force between unlike substances -Results in Capillarity: water moves through/up narrow tube or pores against gravity3
5910114445CohesionAttractive forces between like substances -Causes H2O to change its temperature very slowly4
5910119169CarbonHas 4 outer shell electrons (e-): wants 8 electrons Shares its 4 electrons (e-) with 4 more e-of adjacent atoms (often C, O, H, and/or P/N) As each carbon atom creates 4 covelant bonds around itself a variety of sizes and shapes of molecules result: -chains -rings -networks (or branches)5
5910119170Monomerbasic molecule, a building block, containing C, O, H (1 brick)6
5910121303Polymercreated from 2 or more monomer that link together7
5910123650Macromoleculevery large polymer (1000's monomer)8
5910129355Condensation (Dehydration) Reactionreaction linking monomers together to form polymer (to build larger molecules)9
5910134429Hydrolysisreaction breaking bonds in polymer to form monomers (breaking down large molecules)10
5910134430Organic Compound Groups4 major groups: Carbohydrates, Lipids, Proteins, Nucleic Acids11
5910140142CarbohydratesConsists or C : H : O in a 1 : 2 : 1 ratio Importance: QUICK energy (starch), structural support in plants, product of photosynthesis12
5910142109MonosaccharideMonomer of the Carbohydrate (simple sugars - ex: glucose, fructose, galactose) Chemical formula: C6H12O6 ring13
5910143598Disaccharide2 monosaccharides14
5910147118Polysaccharide3+ monomers of carbohydrates Starch found in plants, Glycogen found in animals, Cellulose found in plant cell walls15
5910542431IsomerDifferent physical arrangements of the same numbers and types of atoms16
5910149662Lipids (fats)Consists of lots of C and H, a little O Do not dissolve in water (Hydrophobic) Importance: Plants; cuticle, waxy coating on plant leaves prevents dehydration, Earwax; in animals serves as waterproof, insect repellent, Lipids store lots of energy in many C-H bonds, Forms cell membranes17
5910161388Fatty AcidMonomer of Lipids in the form of a chain18
5910189155TriglycerideFat polymer, 3 fatty acids and a glycerol At room temperature, fats generally are liquid in plants, solid in animals19
5910198634ProteinsConsist of C, H, O, N Importance: -found in skin and muscles of animals -found in milk, soy products, meat, nuts, eggs -creates enzymes which run chemical reactions inside of cells, help to run metabolism, act as intermediary catalysts in metabolism -speed up, reactions help chemical reactions to occur but they don't get used up in the reaction20
5910201371Amino AcidsMonomer of the protein, 20 different are possible each had a similar basic structure21
5910201372Dipeptide2 amino acids bonded together22
5910204685Polypeptide3+ amino acid bonded together23
5910206481Peptide BondCovelant bond between individual amino acids in a polypeptide24
5910211994Nucleic AcidsConsists of C, O, N, H, P Importance: 1 gene is the code (instructions) for 1 protein25
5910211995NucleotideMonomer of Nucleic Acids N-bases >>> pair up | A-T G-C26
5910214831DNADeoxyribonucleic Acid Contains genetic material = chromosomes = many genes each strand of ___ contains many genes27
5910214832RNARibonuleic Acid Messenger between DNA and the rest of the cell Transfers genetic information from the nucleus to the ribosomes in the cytoplasm to build proteins28
