    About the Lecture

    The lecture Amino Acids – Amines by Adam Le Gresley, PhD is from the course Medical Chemistry.


    Included Quiz Questions

    1. The essential amino acids are dextrorotatory in nature.
    2. There are 20 naturally occurring amino acids.
    3. The amino acids are building blocks of proteins.
    4. All naturally occurring amino acids are levorotatory.
    5. The amino acid molecules have both amine and carboxylic groups attached to the same carbon atom.
    1. All amino acids exist in zwitterion form at pH 7.38.
    2. The dipolar ion or zwitterion is a natural molecule with separate negative and positive charges on the same amino acid.
    3. Amino acid zwitterion contains a carboxylate and an ammonium group due to the Amino acid zwitterions intramolecular acid-base reaction.
    4. The zwitterion of an amino acid is more soluble in water than amino acid molecule due to favorable electrostatic interactions with the surrounding water molecules.
    5. pI or isoelectric point of each amino acid to exist as zwitterion varies from amino acid to amino acid.
    1. …the pH at which an amino acid does not move in an electric field and exists in zwitterion form.
    2. …the pH at which an amino acid does not exist in zwitterion form.
    3. …the pH at which an amino acid moves towards the anode under the influence of an electric field.
    4. …the pH at which an amino acid exists as a conjugate base of carboxylic acid.
    5. …the pH at which an amino acid migrates towards the cathode in an electric field.
    1. The human body is capable of synthesizing essential amino acids at elevated body temperatures.
    2. The nine essential amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
    3. Lack of essential amino acids in the human diet leads to a medical condition or body malfunctioning.
    4. The essential amino acid must be incorporated in the diet to prevent amino acid deficiency disorders.
    5. The human body cannot synthesize the essential amino acids.
