- Consider analysis of a mixture of saturated and unsaturated triacylglycerols (fish oil) and/or fatty acids. Consider 3 methods: IR, NMR and GC-MS (or LC-MS). Do some research to see if and how these methods have been used to characterize these molecules. What structural information can be obtain using each method? What are the limitations of each method? Lastly, if you were to use only one which would provide the most detailed structural characterization? If in the course of your research you come across something better than these three methods, please include it. Include pictures (structures, spectra etc.) and references with hyperlinks.Most cellular proteins are globular. Characterize the tertiary or globular structure from the scheme presented below. Note that this structure includes stretches with secondary structure and also has other interactions between the side chains of different amino acids within the same molecule. Recognize (and indicate by naming) the interactions represented in the diagramThe following structurally define nucleic acids EXCEPT Molecularly, they contain genes that encode for polypeptides and RNA molecules. They are chainlike macromolecules that function in the storage and transfer of genetic information. (C) They are polynucleotides connected covalent linkages. They are polyionic molecules of high molecular weight composed of a specific sequence of subunits called nucleosides.
- Why do heteroatoms and π bonds confer reactivity on a particular molecule?Serine is an uncharged, polar amino acid (below and left). Threonine (below and right) is another uncharged, polar amino acid. Illustrate the hydrolysis of a dipeptide that was made from these two amino acids. Be sure to write all involved reactants and products in the structural form like Serine, and as a proper chemical equation; eg. reactant(s) – product(s). Your diagram of the dipeptide must show the N-terminal and C-terminal ends at opposite sides of the dimer molecule, and you need to indicate where the peptide bond is with an arrow/highlighter. 2.

- Stereochemistry in biological molecules is often denoted by the D- and L- convention, instead of the R- and S- configurations determined by the Cahn-Ingold-Prelog methodology. Naturally occurring a-amino acids are typically in the L-configuration. The Fischer projection of L-alanine is shown. L-alanine H₂N- COOH H- CH3 Identify which structures are equivalent to the L-configuration. CH3 H -NH₂ COOH H COOH NH₂ -CH3The structure shown is an example of a type of macromolecule (carbohydrate, lipid, protein, or nucleic acid) that is an important biological polymer.

- Prostaglandins are a naturally occurring class of compounds in our bodies that affect blood pressure, and cause inflammation and other physiological responses. The synthesis of prostaglandins in our bodies starts with arachidonic acid (see figure below), a long, unsaturated hydrocarbon containing four C=C double bonds and an acid functional group (–COOH). The stereoisomer with all cis double bonds is shown. Draw the stereoisomer with all trans double bonds. Draw the Lewis structures with the formal charges minimized. Do not include formal charges or electron pairs. You do not need to draw hydrogen atoms that are connected to carbon atoms.GenAlex Medical, a little-known division of a major Swiss pharmaceutical firm, recently developed a new synthetic steroid S. Their patent application describes S as "made from a steroid nucleus with hydroxyl groups at positions 3 and 7, and methyl groups at positions 4 and 12." In the drawing space below, draw the chemical structure of S. If more than one structure is possible, you can draw any of them.
