Document Summary

Biol 112 lecture 3 bufers, primary & secondary structure. Bufers: they make the overall soluion resistant to ph change, because they react with both acids and bases. Bufers illustrate the law of mass acion: addiion of reactants accelerates the reacion. Likewise, removal of products accelerates the reacion (towards the product side) Law of mass acion: the rate of any chemical reacion is proporional to the product of the masses of the reacing substances, with each mass raised to a power equal to the coeicient that occurs in the chemical equaion. A conjugate base is formed when an acid donates a proton, ex. Carboxyl group in blood is dissociated because at ph 7. Funcional groups atached to cxhy molecules have diferent funcions: Hydroxyl: r-oh: alcohols: very polar, more soluble. Phosphate: r-po4 : phosphates: breaking o-p bonds releases lots of energy (atp) Sulhydryl: r-sh: when in protons, can form s-s (disulide) bonds that contribute to proton structure.
