The reason for why catalyst does not change the reactants and products at equilibrium has to be explained briefly. Concept Introduction: Reactant: In a chemical reaction the species that present left is denoted as reactant which undergoes chemical change and result to given new species called product. Product: In a chemical reaction the species that present in right side is denoted as product that results from the reactant. Backward Reaction: This type of reaction process involved a reversible, if the products can be converted into a back to reactants. Forward Reaction: This type of reaction has involved irreversible, if obtained product cannot be converted back in to respective reactants under the same conditions. Chemical equilibrium : The term applied to reversible chemical reactions . It is the point at which the rate of the forward reaction is equal to the rate of the reverse reaction. The equilibrium is achieved when the concentrations of reactants and products become constant. Catalyst: The catalyst is a chemical substance that increases the rate of the reaction without participating in the reaction by reducing the activation energy of the reaction.

Interpretation:

The reason for why catalyst does not change the reactants and products at equilibrium has to be explained briefly.

Concept Introduction:

Reactant: In a chemical reaction the species that present left is denoted as reactant which undergoes chemical change and result to given new species called product.

Product: In a chemical reaction the species that present in right side is denoted as product that results from the reactant.

Backward Reaction: This type of reaction process involved a reversible, if the products can be converted into a back to reactants.

Forward Reaction: This type of reaction has involved irreversible, if obtained product cannot be converted back in to respective reactants under the same conditions.

Chemical equilibrium: The term applied to reversible chemical reactions. It is the point at which the rate of the forward reaction is equal to the rate of the reverse reaction. The equilibrium is achieved when the concentrations of reactants and products become constant.

Catalyst: The catalyst is a chemical substance that increases the rate of the reaction without participating in the reaction by reducing the activation energy of the reaction.

The carbon-nitrogen peptide bond is rigid, but rotation can take place about the bond between the nitrogen and a-carbon atoms and the bond between the a-carbon and the carbonyl carbon atom. These bond angles define the conformation of the peptide chain.

Please give an intuitive explanation of the difference, if any, between toxicokinetics and pharmacokinetics.

A protein biochemist attempted to determine the amino acid sequence of a decapeptide. The results from the trypsin, chymotrypsin, and cyanogen bromide treatments are shown: ⚫ Trypsin digestion gave two fragments with multiple residues (not in order): • T1: Ala, Arg, Phe, Gly, Thr, Trp, Tyr o T2: Lys, Met, Val Chymotrypsin digestion gave four fragments with multiple residues (not in order): • CT1: Ala, Phe • CT2: Thr, Trp • CT3: Lys, Met, Tyr, Val 。 CT4: Arg, Gly ⚫ Treatment with cyanogen bromide yielded a single amino acid, methionine, and a nonapeptide. What is a possible sequence of the decapeptide? Use three-letter abbreviations in your answer, and add a dash between each residue.
