7882990820Carbon 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
7882990821Functional groupsSpecial groups of atoms that usually participate in reactions Give different compounds different properties All functional groups important to life are polar1
7882990822HydrophilicWater loving2
7882990823HydrophobicWater hating3
7882990824MacromoleculesGigantic molecules, thousands of atoms4
78829908254 Types of MacromoleculesCarbohydrates, proteins, nucleic acids, lipids5
7882990826MonomersIndividual building blocks of polymers6
7882990827PolymersChains of identical or similar molecules7
7882990828CarbohydratesMain source of energy for cellular work8
7882990829OrganicMostly carbon (C) and Hydrogen (H)9
7882990830InorganicOther elements, little or no C10
7882990831Dehydration SynthesisAdded monomers lose H or OH Release water Bond at oxygen - forms a bridge Polymer formed Building polymers/monomers together11
7882990832Hydrolysis ReactionWater added to break bonds in polymers Reverse of dehydration synthesis Breaking polymers apart12
7882990833Characteristics of CarbohydratesMade up of rings (or ring looking structure) Made up of ration CH2O End in "ose" OH (hydroxyl group)13
7882990834Monosaccharidemonomer Simple sugar14
7882990835Disaccharide2 monosaccharides bonded Double sugar15
7882990836Polysaccharide3 or more monosaccharides bonded Complex carb16
7882990837Function of CarbsShort term energy Storage: polysaccharides17
7882990838GlycogenHow animals store excess sugar Mostly stored in liver and muscle cells When your glucose levels are low, broken down18
7882990839StarchHow plants store extra sugar Humans and other animals can break down Examples: potatoes, plantains, rice19
7882990840CelluloseStructural Make plants rigid Cell walls Can't be broken down by humans and animals Examples: corn, legumes, lettuce20
7882990841LipidsMade mostly of C and H, some O and P Mostly nonpolar Hydrophobic Common lipids: fat, oils, waxes21
7882990842Main Function of LipidsEnergy storage (long term)22
7882990843Additional functions of lipidsCushioning and insulation23
7882990844Monomers that make up lipidsGlycerol and fatty acids24
7882990845Saturated FatNo double bonds in the fatty acid Solid at room temperature SATURATED with hydrogens25
7882990846Unsaturated FatDouble bonds in the fatty acid Liquid at room temperature26
7882990847Trans FatReally bad for you - causing cancer, diabetes, obesity, other health concerns27
7882990848PhospholipidsGlycerol with only two fatty acids Major component of CELL MEMBRANES Form a double layer in water28
7882990849WaxesProtective coat for fruits and animals29
7882990850HormonesSteroids30
7882990851Proteins (Function)Structure, storage, defense, transport, and speeding up reactions Found in hair, muscles, feathers Common foods: meat, eggs, nuts31
7882990852Proteins (Structure)Monomers: amino acids Amino group, carboxyl group, hydrogen and R group Only 20 different R genes Polymers: polypeptides STRUCTURE = FUNCTION32
7882990853Protein SynthesisLink between the C and the N: peptide bond 2 amino acids joined = dipeptide bond33
7882990854Primary Protein StructureChain of amino acids34
7882990855DenaturationUnravel/altar structure of a protein DESTROY35
7882990856Secondary Protein StructureFolding/coiling pattern36
7882990857Tertiary StructureOverall 3D shape37
7882990858Quaternary StructureMultiple polypeptide chains twisted together38
7882990859Nucleic Acids FunctionStore and transmit genetic information Heredity/genetics39
7882990860Nucleic Acid monomersNucleotides40
7882990861Two types of nucleic acidsDNA - Deoxyribonucleic Acid RNA - Ribonucleic Acid41
7882990862Nucleic Acid StructureMade of C, H, O, N and P 5 carbon sugar, phosphate group, nitrogenous base42
