• Carbohydrates are the most abundant class of organic molecules on the planet.
• Carbohydrates account for approximately $75\%$of the dry planet's bulk.

• Fischer devised a simplified method for depicting the atom configurations around the chiral carbons.
• Vertical lines in this three-dimensional structure represent bonds that extend backward from a carbon atom, while horizontal lines represent bonds that extend forward.
• The intersections of horizontal and vertical lines depict chiral carbon atoms.

In this structure, Hydroxy and Bromide have wedged bonds, which means that in the Fischer projection there are horizontal.
