. a. Explain why the melting point of palmitic acid (16 carbons, no double bonds) is slightly lower than that of stearic acid (18 carbons, no double bonds). Explain why the melting point of oleic acid (18 carbons, one double bond) is lower than that of stearic acid b. A mixture of lipids containing phosphatidic acid, cholesterol, testosterone, phosphatidylserine, and phosphatidylethanolamine was applied to a hydrophobic interaction chromatography column. The column was washed with a high salt buffer, and the lipids were then eluted with decreasing salt concentrations. In what order would the lipids be eluted from the column? Explain your answer.
Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.
