Chem week 12 Amines Ammonia NH3 R group Primary amine 1 R group Secondary amine 2 R groups Tertiary Amine 3 R groups Example Methyl Amine R group is CH3 Primary methyl amine most soluble Secondary di methyl amine Tertiary trimethyl amine least soluble Amines are basic meaning they accept protons H Reactions w carboxylic acids Carboxylic acids Amine Amide H20 Tertiary amines don t make amides Amino Acid Zwitter Ion An amino acid with a positive and negative charge and overall 0 charge O of R groups have no charge Amino acidl Amino Acidz peptide Bases accept proton Acids donate proton 2 amino acids dipeptide 3 amino acids tripeptide many amino acids polypeptide protein Types of proteins membrane proteins transport proteins importexport o Membrane proteins stay in one area 0 example I glucose transporter glut I NaK pump ATPase 3 Na OUt 2 K IN 0 Too much sodium too much water too much pressure hypertension high blood pressure Globular proteins 0 Globular proteins go to whole body 0 Carrier Proteins example hemoglobin Hb I 1 Hb can bind to 4 02 molecules I fe3in lungs 9 heart goes to whole body back to lungs again to repeat circulation 0 storage proteins I example myoglobin Mb protein of muscle when this is gone fatigue 0 enzyme proteins I 99 of enzymes are proteins I enzymes are catalysts catalysts lower energy of activation Ea catalysts remain unchanged in a reaction catalysts accelerate rate of chemical reaction I example urea we make this toxic 0 without catalysts rate is SLOWER o with a catalyst rate is FASTER I example urase w urase rate 3x104 sec wo urase rate 3x103910 sec I catalytic power rate of catalyzed reaction rate of uncatalyzed reaction I fast reactions are vital to keep cells alive
