(a)
Interpretation: A number to the anomeric carbon atom of the given
Concept introduction: A compound that possesses a carbon atom which is attached with a hydroxyl group as well as with an alkoxy group is known as hemiacetal compound. This carbon atom that is attached with both hydroxyl group and alkoxy group is known as hemiacetal carbon.
Carbon atom which behaves as a stereocenter in the cyclic form of the hemiacetal compound is known as anomeric carbon.
Haworth projection is a method that is used to provide the three-dimensional cyclic form of a monosaccharide.

- Following are Fischer projections for a group of five-carbon sugars, all of which are aldopentoses. Identify the pairs that are enantiomers and the pairs that are epimers. (The sugars shown here are not all of the possible five-carbon )arrow_forwardThe structure labeled “2” is:arrow_forwardProstaglandins 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.arrow_forward
- Draw the Fischer projection for a monosaccharide.arrow_forwardFollowing are Fischer projection for a group of five carbon sugars,all of which are aldopentoses. Identify the pairs that are enantiomers and the pairs that are epimers.(The sugar shown herebare not all of the possible five carbon sugars.)arrow_forwardTwo of the 20 common amino acids have two chiral carbon atoms in their structures. Identify these amino acids and their chiral carbon atoms.arrow_forward
- D- and L- designations are used to distinguish between the two possible enantiomers of the monosaccharide, galactose. From the Fischer projection, determine the designation of this monosaccharide.arrow_forwardCellulose is a large polysaccharide containing many alpha(1→4) glycosidic linkages and alpha(1→6) glycosidic linkages. True or False?arrow_forward(A) What are Waxes? Draw the structure of wax, which is made up of palmitic acid (16:0) and a saturated 18-carbon alcohol. (В) Consider the structure of menthol. How many isoprene units are present in menthol? (C) What type of isoprene linkage (head-to-tail or tail-to-tail) is present in menthol? Identify the isoprene linkage in the following structure of menthol and indicate by a circle. Menthol =arrow_forward
