Document Summary
Lecture 2: c,h,n,o,p,s make up more than 90% human, water is more dense because molecules are closer together often isotopes are radioactive-have a short half life. Ionic bonds form between (biology: na,mg,ca,k (ie row 3 and 4) and cl. You"re ph stays the same even if you drink a lot of lemon juice: body needs buffers for ex. Dehymoglobin sensitive to ph can"t carry oxygen at wrong ph: buffers illustrate law of mass action: adding reactants accelerates the reaction. Polymerization: condensation, depolymerization, hydrolysis, two monomers form a covalent bond that releases a molecule of water always catalyzed by a specific enzyme, these reactions consume a molecule of water for each covalent bond broken also uses an enzyme. Isomers: same chemical formula; different atom arrangements: structural isomers have a group attached to different carbon atoms, optical isomers have groups attached in dif. Are mirror images of each other still structurally different: occur when a carbon has 4 dif.
