levulose etymology

Etymology:

  • Latin: laevus (left)
  • Suffix: -ose (sugar)

Meaning and Origin:

Levulose is a term used to refer to the sugar fructose. It was first coined by the French chemist and physicist Augustin Jean Fresnel in 1847.

  • "Laevus": This Latin word means "left" and refers to the fact that fructose rotates plane-polarized light to the left (levorotatory).
  • "-ose": This suffix is commonly used in carbohydrate chemistry to indicate a sugar.

Therefore, the term "levulose" literally means "sugar that rotates to the left."

Usage:

Levulose is an outdated term for fructose. Today, the term fructose is more commonly used to refer to this sugar, which is found in fruits, honey, and other sweet foods.
