Neutron | it is neutral located at the center atomic mass - atomic # = # of neutrons |
Protons | +1 located at the center =Atomic number |
Elections | -1 very small mass located in orbitals (electron cloud) =Proton |
Atomic Nucleus | center of atom positive charge |
Atomic number | Protons |
Atomic Mass | Protons - Electrons = mass |
Valance | the valence of an atom or ion is the number of electrons that it can share, give up, or accept from another atom or electron |
Cations | ions with a positive charge |
Anions | ions with a negative charge |
Ionic Bonding | the electrostatic interactions of a cation and an anion |
Covalent Bonding | sharing of electrons between atoms |
Hydrogen Bond | -happens between polar molecules -weak attraction between a partially + hydrogen atom in a molecule and partially - atom in a molecule |
pH | A measurement of free hydrogen ions in a solution |
Acid | -a substance that dissociates in water to produce both an H+ and an anion -proton donor |
Base(Alkaline) | -accepts H+ when added to a solution -proton acceptor |
pH scale | 0-14, 0 being very acidic and 14 being very basic(alkaline), 7 being neutral like water |
Blood pH | 7.35-7.45 |
Water | Always neutral, + charged hydrogen ions and - charged are produced the dissociation of it |
Buffers | substance or group of substances that help prevent pH changes |
Organic Chemicals | those compounds containing carbon atoms |
Carbohydrates | an organic compound containing hydrogen and oxygen in a ratio of 2:1 |
Synthesis | put it together |
Decomposition | take it apart |
Dehydration Synthesis | one subunit looses an H and the other looses an OH to form water molecules as a new covalent bond is produced |
Hydrolysis | H is added to subunit and OH is added to another and the chemical bond between them is broken |
Lipids | Fat like compounds |
Fatty Acids | long chain of hydrocarbons with carboxylic acid functional group at the end |
Monounsaturated | Canola, almond, olive oil |
Saturated | no double bond |
unsaturated | double bond |
Polyunsaturated | two or more double bonds |
Triacylglycerols | -glycerol and 3 fatty acids -long term energy storage -insulation and cushioning |
Phospholipids | -glycerol, 2 fatty acids and a phosphate -membranes -fatty acids have non polar end |
Steroids | -four rings of hydrocarboons -"3 honey combs and an outhouse" -hormones and cholesterol |
Prostagladins and other Eicosanoids | -modified 20 carbon fatty acids that are synthesized as needed from arachidonic acid -communication in nervous system and function in the inflammatory response |
Proteins | -made of amino acids -catalysts(enzymes),defense,transport(hemoglobins)(on membranes), structural support(hair,skin proteins),cause movement(make up muscle cells), regulation(hormones) and storage, pH homeostasis as buffers |
Amino Acids | organic compound containing both a carboxyl (-COOH) and an amino (-NH2) group |
Peptide bonds | hold amino acids together so that a whole protein chain is created -form during dehydration synthesis of amino acids |
Enzyme | act as organic catalysts=chemicals that speed up but are not consumed by chemical reactions |
Enzymes | -must be built properly -the active site does catalyzing -be highly specific on what they work on at the active site -denaturation my happen in not in right environment -sometimes need organic helpers |
Induced fit | Active site changing shape in an enzyme |
Organic Helpers | -coenzymes -all or parts of vitamins |
Co-factors | metalic ions such as Mg++, Zn++, or Ca++ |
Nucleic Acids | macromolecules that store and transfer genetic or hereditary information in cells -made of necluotides(ATP-nitrogenous bas, a sugar, and a phosphate group) |
DNA | -makes proteins such as enzymes -AT,GC -2 stands, sugar= Deoxyribose, Thymine |
RNA | -carry info -AU, GC -1 stand, sugar= Ribose, Uracil |
Polysaccharide | long carbohydrate molecules of monosaccharide units joined together by glycosidic bonds |
Saccharide | simple carbohydrates called monosaccharides with general formula (CH2O)n where n is three or more |
salt | NaCl |
Chlorine | extracted from chloride in salts |
