Definition of the word dextrose

The word "dextrose" is derived from the Latin word "dexter" meaning "right." This is because the molecular structure of dextrose (also known as glucose) is asymmetrical, and when viewed under a microscope, the molecule appears to be three-dimensional with a specific arrangement of atoms. When a molecule has an asymmetrical structure, it can exist as two different isomers, or mirror image molecules. One of these isomers is called dextro- or right-handed, and the other is called levo- or left-handed. Dextrose is the chemical term used to describe the dextro-isomer of glucose, which is the most common form found in nature. Interestingly, the terms "right" and "left" are used to describe the orientation of these molecules because for many years, scientists believed that living organisms, including humans, were also asymmetric in structure, and that the body could distinguish between right and left-handed molecules. This led them to label the dextro-isomer as "right" as it was thought to be more biologically active. However, later scientific discoveries revealed that this was not the case, and the body cannot distinguish between the left and right-handed forms of molecules. Some common sources of dextrose include fruits, honey, and molasses, making it an important ingredient in various food products, including energy drinks and sports supplements. It is also commonly used as a nutrient source in intravenous (IV) infusions in medical settings, as it is easily absorbed and provides a fast source of energy for the body. In summary, the word "dextrose" is derived from the Latin word "dexter" due to the alignment of its molecular structure, and its name is a reflection of the mistaken belief that living organisms could distinguish between left and right-handed molecules.
