Introduction:**This exercise involves drawing the di-peptide formed from glutamic acid (Glu) and lysine (Lys) at neutral pH, and determining whether its isoelectric point (pI) is acidic, neutral, or basic.**2. Description of Amino Acids:**(a) **Lysine (Lys):**``` H2N O | ||H2N-CH- C - OH | CH2 | CH2 | CH2 | CH2 | NH2```**Structure:**- The structure of lysine includes an amino group (H2N) and a carboxyl group (COOH). - The side chain (R group) is four CH2 groups ending in an amino group (NH2).(b) **Glutamic Acid (Glu):**``` H2N O | ||H2N-CH- C - OH | CH2 | CH2 | CH2 | |C O | OH```**Structure:**- The structure of glutamic acid consists of an amino group (H2N) and a carboxyl group (COOH). - The side chain is two CH2 groups followed by a carboxyl group (COOH).**3. Formation of Glu-Lys Di-peptide:**To form the di-peptide Glu-Lys, the carboxyl group of Glu reacts with the amino group of Lys, releasing a molecule of water in a condensation reaction:``` H2N O H2N O | || | ||H2N-CH- C - OH + H2N-CH- C - OH -- | + H2O CH2 | | | CH2 CH2 CH2 | | | CH2 CH2 CH2 | | | C - NH COO NH2 -Oh```**4. Isoelectric Point (pI) Consideration:**- The isoelectric

||| = O MATTER Calculating volume by combining the volume of simple shapes A chemistry student in lab needs to fill a temperature-control tank with water. The tank measures 34.0 cm long by 17.0 cm wide by 14.0 cm deep. In addition, as shown in the sketch below, the student needs to allow 2.0 cm between the top of the tank and the top of the water, and a round-bottom flask with a diameter of 11.5 cm will be just barely submerged in the water. Calculate the volume of water in liters which the student needs. Round your answer to the nearest 0.01 L. Explanation Check 2 cm water X flask 21 OL m stv X 1/3 5 Kirste Ⓒ2023 McGraw Hill LLC.
