8118675332Carbon 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
8118675333Functional groupsSpecial groups of atoms that usually participate in reactions Give different compounds different properties All functional groups important to life are polar1
8118675334HydrophilicWater loving2
8118675335HydrophobicWater hating3
8118675336MacromoleculesGigantic molecules, thousands of atoms4
81186753374 Types of MacromoleculesCarbohydrates, proteins, nucleic acids, lipids5
8118675338MonomersIndividual building blocks of polymers6
8118675339PolymersChains of identical or similar molecules7
8118675340CarbohydratesMain source of energy for cellular work8
8118675341OrganicMostly carbon (C) and Hydrogen (H)9
8118675342InorganicOther elements, little or no C10
8118675343Dehydration SynthesisAdded monomers lose H or OH Release water Bond at oxygen - forms a bridge Polymer formed Building polymers/monomers together11
8118675344Hydrolysis ReactionWater added to break bonds in polymers Reverse of dehydration synthesis Breaking polymers apart12
81186753454 Characteristics of CarbohydratesMade up of rings (or ring looking structure) Made up of ration CH2O End in "ose" OH (hydroxyl group)13
8118675346Monosaccharidemonomer Simple sugar14
8118675347Disaccharide2 monosaccharides bonded Double sugar15
8118675348Polysaccharide3 or more monosaccharides bonded Complex carb16
8118675349Function of CarbsShort term energy Storage: polysaccharides17
8118675350GlycogenHow animals store excess sugar Mostly stored in liver and muscle cells When your glucose levels are low, broken down18
8118675351StarchHow plants store extra sugar Humans and other animals can break down Examples: potatoes, plantains, rice19
8118675352CelluloseStructural Make plants rigid Cell walls Can't be broken down by humans and animals Examples: corn, legumes, lettuce20
8118675353LipidsMade mostly of C and H, some O and P Mostly nonpolar Hydrophobic Common lipids: fat, oils, waxes21
8118675354Main Function of LipidsEnergy storage (long term)22
8118675355Additional functions of lipidsCushioning and insulation23
8118675356Monomers that make up lipidsGlycerol and fatty acids24
8118675357Saturated FatNo double bonds in the fatty acid Solid at room temperature SATURATED with hydrogens25
8118675358Unsaturated FatDouble bonds in the fatty acid Liquid at room temperature26
8118675359Trans FatReally bad for you - causing cancer, diabetes, obesity, other health concerns27
8118675360PhospholipidsGlycerol with only two fatty acids Major component of CELL MEMBRANES Form a double layer in water28
8118675361WaxesProtective coat for fruits and animals29
8118675362HormonesSteroids30
8118675363Proteins (Function)Structure, storage, defense, transport, and speeding up reactions Found in hair, muscles, feathers Common foods: meat, eggs, nuts31
8118675364Proteins (Structure)Monomers: amino acids Amino group, carboxyl group, hydrogen and R group Only 20 different R genes Polymers: polypeptides STRUCTURE = FUNCTION32
8118675365Protein SynthesisLink between the C and the N: peptide bond 2 amino acids joined = dipeptide bond33
8118675366Primary Protein StructureChain of amino acids34
8118675367DenaturationUnravel/altar structure of a protein DESTROY35
8118675368Secondary Protein StructureFolding/coiling pattern36
8118675369Tertiary StructureOverall 3D shape37
8118675370Quaternary StructureMultiple polypeptide chains twisted together38
8118675371Nucleic Acids FunctionStore and transmit genetic information Heredity/genetics39
8118675372Nucleic Acid monomersNucleotides40
8118675373Two types of nucleic acidsDNA - Deoxyribonucleic Acid RNA - Ribonucleic Acid41
8118675374Nucleic Acid StructureMade of C, H, O, N and P 5 carbon sugar, phosphate group, nitrogenous base42
