Olestra has been used in certain snack foods as an alternativeto fats and oils. Its structure consists of a sucrose molecule inwhich all free hydroxyl groups have formed esters with oleicacid (an 18-carbon monounsaturated fatty acid). Olestra molecules contain no calories because they are exceptionallylarge and cannot be digested. Draw the structure of olestra.Use R—COOH as an abbreviation for oleic acid.
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.
