BIOC12H3 Lecture Notes - Lactate Dehydrogenase, Enzyme Kinetics, Invertase
Document Summary
Bioc12fall2012 lecture week 10 notes: enzymes classification and kinetics (chapter 13) 2: 1 = oxireductases, 2 = transferases, 3 = hydrolases digestive enzymes, can break larger proteins into smaller proteins, 4 = lyases, 5 = isomerases, 6 = ligases, relatice amounts of these enzymes. Lyases: catalyze lysis of substrate by generating a double bond, example: 3: example of metal ions as cofactors: fe2+, fe3+, k+, cu2+, etc. Vitamins coenzyme precursors: the vitamin is converted into a special form which aids in specific reactions as a coenzyme. First order reactions: a p and v = -d[a]/dt = d[p]/dt = k[a, t1/2 is a constant which is the half life of a, t1/2 = 0. 693/k. Properties of second order reaction: 2a p. [at][a0]=e-kt][102/1akt : the half life depends on the initial concentration of a. E + s: assumption: enzyme binds to substrate and reaches eq very quickly where ks is the dissociation constant.
