Answer #1

ANSWER:

The structure of a fatty acid involves a long hydrocarbon chain with a acid group at one end of the molecule. The most common chain length of natural fatty acids is 17-19 carbons long. When a double-bond is present in a natural fatty acid, the stereochemistry of the bond is in the cis orientation so that a kink is generated in the hydrocarbon chain. This kink disrupts association of adjacent hydrocarbon chains by repulsion tending to decrease the melting point of the fatty acid or lipid.

Stearic acid and linoleic acid are both long chain carboxylic acids with 18 carbon atoms. However, there is a vast difference in the melting points of these fatty acids. Stearic acid (18:0) melts at 70°C and linoleic acid (18:2) melts at -5°C. Explain why there is such a large difference in the melting points of these fatty acids.

The pKa for a typical long chain fatty acid is approximately 5. In an aqueous solution at pH>7, these fatty acids will spontaneously form micelles. In the same solution at pH>5, these fatty acids are no longer capable of micelle formation. Explain the observed difference in behavior of the fatty acid between these two conditions, specifically adressing the forces and interactions that drive micelle formation vs. non-specific aggregation of fatty acids.

Proteins are long-chains of amino acids linked together. In solution, these chains tend to fold in certain ways to give the protein a structure. This folding depends on the intermolecular forces (IMFs) between water (or other molecules) and the various amino acid side-chains, as well as the IMFs between different side chains. 1.The amino acid asparagine has a melting point of 241oC whereas that of isoleucine is 295oC. Explain this difference on the basis of IMFs. HINT: it may not...
