8491701314Carbon 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
8491701315Functional groupsSpecial groups of atoms that usually participate in reactions Give different compounds different properties All functional groups important to life are polar1
8491701316HydrophilicWater loving2
8491701317HydrophobicWater hating3
8491701318MacromoleculesGigantic molecules, thousands of atoms4
84917013194 Types of MacromoleculesCarbohydrates, proteins, nucleic acids, lipids5
8491701320MonomersIndividual building blocks of polymers6
8491701321PolymersChains of identical or similar molecules7
8491701322CarbohydratesMain source of energy for cellular work8
8491701323OrganicMostly carbon (C) and Hydrogen (H)9
8491701324InorganicOther elements, little or no C10
8491701325Dehydration SynthesisAdded monomers lose H or OH Release water Bond at oxygen - forms a bridge Polymer formed Building polymers/monomers together11
8491701326Hydrolysis ReactionWater added to break bonds in polymers Reverse of dehydration synthesis Breaking polymers apart12
84917013274 Characteristics of CarbohydratesMade up of rings (or ring looking structure) Made up of ration CH2O End in "ose" OH (hydroxyl group)13
8491701328Monosaccharidemonomer Simple sugar14
8491701329Disaccharide2 monosaccharides bonded Double sugar15
8491701330Polysaccharide3 or more monosaccharides bonded Complex carb16
8491701331Function of CarbsShort term energy Storage: polysaccharides17
8491701332GlycogenHow animals store excess sugar Mostly stored in liver and muscle cells When your glucose levels are low, broken down18
8491701333StarchHow plants store extra sugar Humans and other animals can break down Examples: potatoes, plantains, rice19
8491701334CelluloseStructural Make plants rigid Cell walls Can't be broken down by humans and animals Examples: corn, legumes, lettuce20
8491701335LipidsMade mostly of C and H, some O and P Mostly nonpolar Hydrophobic Common lipids: fat, oils, waxes21
8491701336Main Function of LipidsEnergy storage (long term)22
8491701337Additional functions of lipidsCushioning and insulation23
8491701338Monomers that make up lipidsGlycerol and fatty acids24
8491701339Saturated FatNo double bonds in the fatty acid Solid at room temperature SATURATED with hydrogens25
8491701340Unsaturated FatDouble bonds in the fatty acid Liquid at room temperature26
8491701341Trans FatReally bad for you - causing cancer, diabetes, obesity, other health concerns27
8491701342PhospholipidsGlycerol with only two fatty acids Major component of CELL MEMBRANES Form a double layer in water28
8491701343WaxesProtective coat for fruits and animals29
8491701344HormonesSteroids30
8491701345Proteins (Function)Structure, storage, defense, transport, and speeding up reactions Found in hair, muscles, feathers Common foods: meat, eggs, nuts31
8491701346Proteins (Structure)Monomers: amino acids Amino group, carboxyl group, hydrogen and R group Only 20 different R genes Polymers: polypeptides STRUCTURE = FUNCTION32
8491701347Protein SynthesisLink between the C and the N: peptide bond 2 amino acids joined = dipeptide bond33
8491701348Primary Protein StructureChain of amino acids34
8491701349DenaturationUnravel/altar structure of a protein DESTROY35
8491701350Secondary Protein StructureFolding/coiling pattern36
8491701351Tertiary StructureOverall 3D shape37
8491701352Quaternary StructureMultiple polypeptide chains twisted together38
8491701353Nucleic Acids FunctionStore and transmit genetic information Heredity/genetics39
8491701354Nucleic Acid monomersNucleotides40
8491701355Two types of nucleic acidsDNA - Deoxyribonucleic Acid RNA - Ribonucleic Acid41
8491701356Nucleic Acid StructureMade of C, H, O, N and P 5 carbon sugar, phosphate group, nitrogenous base42
