Over 90% of dietary fats are in the form of triglycerides, composed of fatty acids and glycerol. A key system for classifying these fats in nutrition and biochemistry is the omega nomenclature. This system helps to understand the structural differences and profound health impacts of various fatty acids.

Omega-3 fatty acids are polyunsaturated fats essential for human health that the body cannot produce efficiently on its own. Understanding their different names is crucial for navigating nutrition labels, scientific literature, and making informed dietary choices.

In the mid-19th century, chemists first coined the term 'carbohydrate' based on a simple, yet flawed, observation. This old definition described these compounds as 'hydrates of carbon,' represented by the empirical formula $C_n(H_2O)_m$, reflecting the seeming equal ratio of hydrogen and oxygen atoms to those in water.

Every cell in the human body is surrounded by a membrane made of lipids, which are often composed of fatty acids. Understanding the structure of these fundamental molecules, particularly their two distinct ends, is crucial for grasping their biological functions. The two ends of a fatty acid have very different chemical properties and are named using both standard chemical and nutritional nomenclature.

According to the U.S. Food and Drug Administration, caffeine is a "Multiple Purpose Generally Recognized as Safe Food Substance", but the ubiquitous substance is known by many different monikers, leading to the question: what is caffeine referred to as in its various forms?

The term "omega-3" isn't a marketing gimmick but a precise chemical designation based on a fatty acid's molecular structure. This name was established by organic chemists to systematically classify polyunsaturated fatty acids based on the position of their first double bond. The number '3' refers to the position of this double bond from the fatty acid's 'omega' end.
