What is with the names of vitamins and other science terminology?

Navigating the world of vitamins can feel like decoding a cryptic puzzle. Just as every household has its unique way of organizing and naming things, the scientific community has its conventions for naming vitamins and other scientific terms. Let's make sense of why vitamins have the names they do, and how this naming convention extends into broader scientific terms.

A Brief History of Vitamin Names

Imagine walking into a library where books are organized not by titles, but by the benefits they provide. Similarly, when vitamins were first discovered, they were given a name based on their biological activity rather than their chemical structure. The name "vitamin" itself is a mash-up of "vita," meaning life, and "amine," reflecting the initial (but incorrect) assumption that these compounds were amines. The discovery of vitamins marked a revolution in nutrition science, revealing that certain "invisible" compounds in food were essential for health, growth, and survival.

The Alphabet Soup of Vitamins

The early 20th century saw vitamins being named in a seemingly straightforward manner: Vitamin A, B, C, and so on, much like naming your firstborn, secondborn, etc. This naming convention, proposed by Jack Drummond in 1920, simplified the previously chaotic nomenclature and reflected a discovery order rather than chemical structures.

However, the plot thickened with the discovery of the B-complex vitamins. It turns out, Vitamin B was not a single entity but a family of vitamins with different functions. This led to a subdivision using numbers (e.g., B1, B2, B12), like assigning each member of a large family a unique identifier to distinguish them at a family reunion.

Why the Gaps and Jumps?

The vitamin naming system has its share of gaps and mysteries, akin to missing pieces in a puzzle. Over time, some substances initially thought to be vitamins were reclassified after it was discovered that they could be synthesized by the human body and thus didn't meet the strict definition of a vitamin. This reclassification led to the discontinuation of their vitamin status and names, creating gaps in the vitamin alphabet. For example vitamin F is now known as the Omega Fatty Acids ALA (alpha-linolenic acid) and LA (linolenic acid).

Beyond Vitamins: Scientific Naming Conventions

The story of vitamin names is just one chapter in the larger book of scientific nomenclature (a system of naming things). In science, names often reflect a substance's function, source, or the structure rather than being arbitrarily chosen. For instance, enzymes end with "-ase" (like lactase, which breaks down lactose), and molecules with a ring structure might include "cyclo" in their names (like cyclohexane). This system, while complex, helps scientists around the world speak a common language, facilitating collaboration and discovery.

Embracing the Complexity

Understanding the naming conventions of vitamins and other scientific terms is like learning a new language. It may seem daunting at first, with its rules and exceptions, but it offers a better view into the world of science. By appreciating the history and logic behind these names, we can more easily learn and take accountability for our own well-being. Embracing this complexity can help us find clarity and purpose in our pursuit of health and knowledge.

Speaking of vitamins, make sure you are avoiding any nutrient deficiencies by using a proper multi-vitamin which includes methylated variants that our body can actually use. I highly recommend Optimize by 10x Health Systems.
