6460544499AdhesionWater molecule attracts other polar molecules1
6460548337Atoms that constitute organic moleculesCHONPS2
6460554377HydrocarbonsEthane (2 C's), Propane (3 C's), and Butane (4 C's)3
6460556958IsomersSame number of atoms, but different structures4
6460561157Cis IsomerCreates a flat mountain shape5
6460561158Trans IsomerCreates a zig-zag shape6
6460573054EnantiomersIsomers that are mirrors of each other7
6460577930Functional GroupsHydroxyl groups, Carbonyl groups, Carboxylic groups, Amino groups, Sulfhydryl groups, Phosphate groups.8
6460593129Hydroxyl groupAlcohols: -OH or -HO9
6460596536Carbonyl groupKetone: =O in the middle Aldehyde: =O at the end10
6460615943Carboxylic groupCarboxylic acid (gives away H+, is acidic, has a negative charge, is polar): =O and -OH11
6460623125Amino groupAmine (is basic, has a positive charge, is polar): -NH212
6460633436Sulfhydryl groupThiol: -SH13
6460638520Phosphate groupOrganic Phosphate (has negative charge)14
6460654531Dehydration SynthesisRemoves H20 to make macromolecule more complex (anabolic)/ to build15
6460661994HydrolysisAdds H20 to reduce complexity (catabolic)/ to break things down16
6461278693MacromoleculesCarbohydrates, Lipids, Proteins, and Nucleic Acids.17
6460665764ProteinsMade up of C, H, O, and a little S. Proteins are polymers of amino acid monomers joined by peptide bonds. Ex: enzymes, antibodies, hemoglobin18
6461306340HemoglobinAn oxygen-transport protein in red blood cells19
6460826897EnzymesA type of protein that acts a biological catalyst (speeds up process by lowering activation energy). Substrate fits into the enzyme's active site.20
6460842853Competitive InhibitorActs as a fake substrate to the block active site of an enzyme21
6460846574Noncompetitive InhibitorAttaches to the allo-steric site and changes the shape of the active site of an enzyme to render it useless.22
6460677545Primary Structure for ProteinsThe long chain of amino acids23
6460677546Secondary Structure for ProteinsAlpha Helix Beta Plated Sheets24
6460679760Tertiary Structure for ProteinsThe 3D shape of the chain, held by R group attractions25
6460697060Quartenary Structure for ProteinsThe 3D shape made of more than one polypeptide chain, held by R group attractions26
6460702015Nucleic AcidsMade up of C, H, O, N, and P. There are two types: DNA and RNA. Nucleic Acids are polymers of nucleotides (phosphate + pentose sugar + nitrogenous base [ex: ATP])27
6460717334CarbohydratesMade up of C, 2H, O (C + H20). These polymers made of monosaccharides (glucose, fructose, galactose, ribose) are sugars and starches used for short term energy since there are less bonds=less energy.28
6460745084LipidsMade up of C, H, and some O. They are nonpolar fats, oils, and waxes used for longer term energy.29
6460754912Saturated FatsAre solid at room temperature and can be compact30
6460754913Unsaturated FatsAre liquid at room temperature. There is 1+ cis isomers/double bonds that takes up space=can't be compact.31
6460774053TriglyceridesA type of lipid that consist of one glycerol and 3 fatty acids32
6461273132GlycerolAn alcohol with 3 carbons33
6460780265PhospholipidsA type of lipid that makes molecules both nonpolar and polar [Ex: cell membranes]. They consist of one glycerol, 2 fatty acids, and a polar head group with phosphate34
6460807658SteroidsA type of lipid that includes hormones, cholesterol, and vitamins. It consists of 4 carbon rings with no fatty acid tails35
