8596335732Carbon 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
8596335733Functional groupsSpecial groups of atoms that usually participate in reactions Give different compounds different properties All functional groups important to life are polar1
8596335734HydrophilicWater loving2
8596335735HydrophobicWater hating3
8596335736MacromoleculesGigantic molecules, thousands of atoms4
85963357374 Types of MacromoleculesCarbohydrates, proteins, nucleic acids, lipids5
8596335738MonomersIndividual building blocks of polymers6
8596335739PolymersChains of identical or similar molecules7
8596335740CarbohydratesMain source of energy for cellular work8
8596335741OrganicMostly carbon (C) and Hydrogen (H)9
8596335742InorganicOther elements, little or no C10
8596335743Dehydration SynthesisAdded monomers lose H or OH Release water Bond at oxygen - forms a bridge Polymer formed Building polymers/monomers together11
8596335744Hydrolysis ReactionWater added to break bonds in polymers Reverse of dehydration synthesis Breaking polymers apart12
85963357454 Characteristics of CarbohydratesMade up of rings (or ring looking structure) Made up of ration CH2O End in "ose" OH (hydroxyl group)13
8596335746Monosaccharidemonomer Simple sugar14
8596335747Disaccharide2 monosaccharides bonded Double sugar15
8596335748Polysaccharide3 or more monosaccharides bonded Complex carb16
8596335749Function of CarbsShort term energy Storage: polysaccharides17
8596335750GlycogenHow animals store excess sugar Mostly stored in liver and muscle cells When your glucose levels are low, broken down18
8596335751StarchHow plants store extra sugar Humans and other animals can break down Examples: potatoes, plantains, rice19
8596335752CelluloseStructural Make plants rigid Cell walls Can't be broken down by humans and animals Examples: corn, legumes, lettuce20
8596335753LipidsMade mostly of C and H, some O and P Mostly nonpolar Hydrophobic Common lipids: fat, oils, waxes21
8596335754Main Function of LipidsEnergy storage (long term)22
8596335755Additional functions of lipidsCushioning and insulation23
8596335756Monomers that make up lipidsGlycerol and fatty acids24
8596335757Saturated FatNo double bonds in the fatty acid Solid at room temperature SATURATED with hydrogens25
8596335758Unsaturated FatDouble bonds in the fatty acid Liquid at room temperature26
8596335759Trans FatReally bad for you - causing cancer, diabetes, obesity, other health concerns27
8596335760PhospholipidsGlycerol with only two fatty acids Major component of CELL MEMBRANES Form a double layer in water28
8596335761WaxesProtective coat for fruits and animals29
8596335762HormonesSteroids30
8596335763Proteins (Function)Structure, storage, defense, transport, and speeding up reactions Found in hair, muscles, feathers Common foods: meat, eggs, nuts31
8596335764Proteins (Structure)Monomers: amino acids Amino group, carboxyl group, hydrogen and R group Only 20 different R genes Polymers: polypeptides STRUCTURE = FUNCTION32
8596335765Protein SynthesisLink between the C and the N: peptide bond 2 amino acids joined = dipeptide bond33
8596335766Primary Protein StructureChain of amino acids34
8596335767DenaturationUnravel/altar structure of a protein DESTROY35
8596335768Secondary Protein StructureFolding/coiling pattern36
8596335769Tertiary StructureOverall 3D shape37
8596335770Quaternary StructureMultiple polypeptide chains twisted together38
8596335771Nucleic Acids FunctionStore and transmit genetic information Heredity/genetics39
8596335772Nucleic Acid monomersNucleotides40
8596335773Two types of nucleic acidsDNA - Deoxyribonucleic Acid RNA - Ribonucleic Acid41
8596335774Nucleic Acid StructureMade of C, H, O, N and P 5 carbon sugar, phosphate group, nitrogenous base42
