Question
Chapter 3.1, Problem 4CC
Summary Introduction
To draw:
The structure where, from a cysteine molecule, the NH2 group is replaced with a COOH (carboxyl) group. Also, determine how this change would alter the chemical properties and state whether the central carbon atomis asymmetric after or before the alteration.
Concept introduction:
Amino acids are the molecules that are organic and consist of both the carboxyl and amino groups.

behenic acid
Which of the following best explains why erucic acid is liquid at room temperature but behenic acid is solid at
room temperature?
O
OH
The presence of a double carbon to carbon bond in erucic acid prevents the molecule
from packing closely together.
The lack of any double carbon-carbon bonds in behenic acid causes the molecule to be
come polar and therefore packed more tightly.
The larger number of carbon atoms in erucic acid prevents the molecule from packing
tightly together.
OH
The smaller number of carbon atoms in behenic acid creates stronger covalent bonds
between the carbon atoms allowing for them to pack more tightly together.

- DRAW IT Suppose you had an organic molecule suchas cysteine (see Figure 4.9, sulfhydryl group example),and you chemically removed the —NH2 group andreplaced it with —COOH. Draw this structure.

One of these lipids is built from oleic acid and a 32-carbon fatty acid that has a double bond between carbons 9 and 10 and a hydroxyl group attached to the omega carbon. The carboxyl group of oleic acid condenses with the hydroxyl group in the longer lipid. Draw the structure of the reaction product. It’s OK to draw a condensed structure.arrow_forward
- When a substance such as sodium chloride is dissolved in water, the ions become completely surrounded by water molecules, forming structures called hydration spheres. When the sodium salt of a fatty acid is mixed with water, the carboxylate group of the molecule becomes hydrated, but the hydrophobic portion of the molecule is poorly hydrated, if at all.
