8085063843Carbon compoundscontain carbon, make up living things Can form 4 bonds Bonds can be with other elements or carbon Can be lots of shapes and sizes0
8085063844Functional groupsSpecial groups of atoms that usually participate in reactions Give different compounds different properties All functional groups important to life are polar1
8085063845HydrophilicWater loving2
8085063846HydrophobicWater hating3
8085063847MacromoleculesGigantic molecules, thousands of atoms4
80850638484 Types of MacromoleculesCarbohydrates, proteins, nucleic acids, lipids5
8085063849MonomersIndividual building blocks of polymers6
8085063850PolymersChains of identical or similar molecules7
8085063851CarbohydratesMain source of energy for cellular work8
8085063852OrganicMostly carbon (C) and Hydrogen (H)9
8085063853InorganicOther elements, little or no C10
8085063854Dehydration SynthesisAdded monomers lose H or OH Release water Bond at oxygen - forms a bridge Polymer formed Building polymers/monomers together11
8085063855Hydrolysis ReactionWater added to break bonds in polymers Reverse of dehydration synthesis Breaking polymers apart12
80850638564 Characteristics of CarbohydratesMade up of rings (or ring looking structure) Made up of ration CH2O End in "ose" OH (hydroxyl group)13
8085063857Monosaccharidemonomer Simple sugar14
8085063858Disaccharide2 monosaccharides bonded Double sugar15
8085063859Polysaccharide3 or more monosaccharides bonded Complex carb16
8085063860Function of CarbsShort term energy Storage: polysaccharides17
8085063861GlycogenHow animals store excess sugar Mostly stored in liver and muscle cells When your glucose levels are low, broken down18
8085063862StarchHow plants store extra sugar Humans and other animals can break down Examples: potatoes, plantains, rice19
8085063863CelluloseStructural Make plants rigid Cell walls Can't be broken down by humans and animals Examples: corn, legumes, lettuce20
8085063864LipidsMade mostly of C and H, some O and P Mostly nonpolar Hydrophobic Common lipids: fat, oils, waxes21
8085063865Main Function of LipidsEnergy storage (long term)22
8085063866Additional functions of lipidsCushioning and insulation23
8085063867Monomers that make up lipidsGlycerol and fatty acids24
8085063868Saturated FatNo double bonds in the fatty acid Solid at room temperature SATURATED with hydrogens25
8085063869Unsaturated FatDouble bonds in the fatty acid Liquid at room temperature26
8085063870Trans FatReally bad for you - causing cancer, diabetes, obesity, other health concerns27
8085063871PhospholipidsGlycerol with only two fatty acids Major component of CELL MEMBRANES Form a double layer in water28
8085063872WaxesProtective coat for fruits and animals29
8085063873HormonesSteroids30
8085063874Proteins (Function)Structure, storage, defense, transport, and speeding up reactions Found in hair, muscles, feathers Common foods: meat, eggs, nuts31
8085063875Proteins (Structure)Monomers: amino acids Amino group, carboxyl group, hydrogen and R group Only 20 different R genes Polymers: polypeptides STRUCTURE = FUNCTION32
8085063876Protein SynthesisLink between the C and the N: peptide bond 2 amino acids joined = dipeptide bond33
8085063877Primary Protein StructureChain of amino acids34
8085063878DenaturationUnravel/altar structure of a protein DESTROY35
8085063879Secondary Protein StructureFolding/coiling pattern36
8085063880Tertiary StructureOverall 3D shape37
8085063881Quaternary StructureMultiple polypeptide chains twisted together38
8085063882Nucleic Acids FunctionStore and transmit genetic information Heredity/genetics39
8085063883Nucleic Acid monomersNucleotides40
8085063884Two types of nucleic acidsDNA - Deoxyribonucleic Acid RNA - Ribonucleic Acid41
8085063885Nucleic Acid StructureMade of C, H, O, N and P 5 carbon sugar, phosphate group, nitrogenous base42
