BIOL 115 Lecture Notes - Lecture 3: Carboxylic Acid, Hydrogen Bond, Amine
Document Summary
Enzymes speed up chemical reactions without being used up by lowering the activation energy. They lower the transition state so that they are low enough to initiate a drive. Enzymes are saturated when all binding sites are occupied, a further increase in the substrate concentration will no longer increase the rate of product formation; this is the maximum speed of reaction which changes from enzyme to enzyme. 1. only reactions with the overall negative g^ can be catalyzed, the ^g does not change any substance that speeds up a chemical reaction without itself being used up. Citrate synthase: substrates are close and in correct orientation. Build hair, make dna, catalyze metabolic reactions, etc. There are 20 amino acids which all fall under: non polar, polar, hydrophobic, or charged amino acids. Peptide bonds occur between the carboxyl group, one amino acid and the amino group of the next amino acid.
