Morphology

vitamin + A1

The compound 'vitamin A1' is compositionally built from 'vitamin' plus a label 'A1', so learners who know the constituents can infer it denotes a specific subtype of vitamin A. However, the precise biochemical identity (retinol, unsaturated alcohol, synthesis from carotene) is technical and not derivable from the parts alone, so the meaning is only partially predictable without prior exposure.

Etymology

Vitamin A1: The name vitamin A1 comes from early scientists who called vitamins 'vital amines' and used the letter A for the first group they found. Because this substance was found in fish liver oil and carrots and helps the eyes, vitamin A1 now means the eye-helping chemical retinol.
