Acid catalyst - Study guides, Class notes & Summaries

MCAT Chem/PhysGenerally, how are proteins formed? The connecting of a string of amino acids via peptide bonds and the folding of this string to create a completed protein. The folding is determined primarily by the hydrophilic and/or hydrophobic nature of the amino acids. Stabilized by hydrogen bonds, disulfide bridges, and other intramolecular forces. Peptide (Amide) Bonds These are formed when the n-terminus of one amino acid attacks the carboxy terminus of another amino acid. Water is ...

T or F: A biochemical reaction, without a catalyst or thermodynamic coupling, takes 50 years to reach a state of equilibrium. W/o more information, we cannot make a determination on either the value of the Keq constant or the positive or negative value of the DeltaG of the reaction Correct Answer-False T or F: Due to its small size, the amino acid glycine can be found in tight turns in a protein structure Correct Answer-True T or F: The Delta G of a reaction is defined as the energy requir...
