Drawing Haworth Structures of Sugars Draw Haworth structures for the two possible isomers of D-altrose (Figure 7.2) and D-psicose (Figure 7.3).
Interpretation: The Haworth structures for two possible isomers of
Concept introduction: The simplest hydrolyzed form that is obtained from the carbohydrates is known as a monosaccharide.
Haworth projection is a method that is used to provide the three-dimensional cyclic form of a monosaccharide. This method shows the monosaccharide in the form of a hemiacetal ring or hemiketal ring.
Carbon atom which behaves as a stereocenter or a chiral center in the cyclic ring form of the hemiacetal or hemiketal compound is known as anomeric carbon.

To fully appreciate the elements of secondary structure in proteins, it is useful to have a practical sense of their structures. On a piece of paper, draw a simple but large zigzag pattern to represent a -strand. Then fill in the structure, drawing the locations of the moms of the chain on this zigzag pattern. Then draw a simple, large coil on a piece of paper to represent an -helix. Then fill in the structure, drawing the backbone atoms in the correction locations along the coil and indicating the locations of the R groups in your drawing.arrow_forward
