Valine is an essential amino acid, which means that it cannot be manufactured in the body and must be obtained through dietary sources. It is a branched-chain amino acid that works with the other two BCAAs (isoleucine & leucine) to promote normal growth, repair tissues, regulate blood sugar, and provide the body with energy. Correct each of the three drawings below (i.e., add or remove lone pairs, charges, and atoms) to show valine at pH 1, pH 7, and pH 11. The pKa values for valine's ionizable groups are 2.29 for the –COOH group and 9.72 for the –NH3+ group. (same drawing on each part)
Electronic Effects
The effect of electrons that are located in the chemical bonds within the atoms of the molecule is termed an electronic effect. The electronic effect is also explained as the effect through which the reactivity of the compound in one portion is controlled by the electron repulsion or attraction producing in another portion of the molecule.
Drawing Resonance Forms
In organic chemistry, resonance may be a mental exercise that illustrates the delocalization of electrons inside molecules within the valence bond theory of octet bonding. It entails creating several Lewis structures that, when combined, reflect the molecule's entire electronic structure. One Lewis diagram cannot explain the bonding (lone pair, double bond, octet) elaborately. A hybrid describes a combination of possible resonance structures that represents the entire delocalization of electrons within the molecule.
Using Molecular Structure To Predict Equilibrium
Equilibrium does not always imply an equal presence of reactants and products. This signifies that the reaction reaches a point when reactant and product quantities remain constant as the rate of forward and backward reaction is the same. Molecular structures of various compounds can help in predicting equilibrium.
