CSHS Quiz 16

Phenylalanine has the highest molar mass above, since it has 9 Carbons like the other aromatic compounds, but has 2 Oyxgen and a Nitrogen, and the Hydrogen are much smaller.

The circles in the Benzene rings above are just art, and tell you nothing about how the electrons are shared between the six Carbons.

3-Oxobutanoic acid is a ketone, and supplies much of the energy used by people in ketosis, who use fat for most of their energy needs instead of glucose.

Ethanol is less toxic than Methanol or Isopropyl Alcohol, but is still deadly if it is absorbed by your intestines faster than your liver can detoxify it.

Ethyl Benzoate is an ester formed by reacting Ethanol with Benzoic Acid, a Carboxylic acid. It is used chemists to make fruit scented perfumes and artificial food flavoring.

Cinnamaldehyde is responsible for most of the flavor and aroma of Cinnamon

The aliphatic compounds shown are Cinnamaldehyde, Phenylalanine, and Ethyl Benzoate

The aromatic compounds shown are 3-Oxobutanoic acid, Ethanol, and Cysteine

Like Phenylalanine, Cysteine is an amino acid used to build our proteins. People with curly hair have more covalent cross-linking bonds between the Sulfur in the Cysteine amino acids that make their hair curl.

Phenylalanine is one of the monomers our body links together to make starches

The six phospholipids above are arranged like they are in a phospholipid bilayer, which forms the cell membrane in all living cells.

Glucose is produced by photosynthesis and reacts with Oxygen in all living things to produce Carbon Dioxide, water, and release energy.

The nonpolar hydrophobic lipid chains of the phospholipids are attracted to water inside and outside of the cells, and the hydrophilic polar, acidic phosphate ends of the phospholipids are not attracted to water.

Glucose is a carbohydrate, and is contained only in sweet foods like candy, not in starchy foods like potatoes, tortillas and rice.
