1. vit- "life" + -amin (原为-amine, 由于后来发现其中没有氨基酸，顾将后面的字母e去掉了，其实作为物质的代称，现在加不加字母e都没什么关系啦)。
2. 该词有两种译名，一种是意译，即“维生素”，表示维持生命的元素，顾简称为维生素；另一种是音译，即“维他命”，根据发音直译过来的，很好理解。
vitamin 维他命，生命素最早写做vitamine,来自vit-,生命，-amine,氨。后证实这种物质不属于氨基，因此字母e脱落。
- vitamin
- vitamin: [20] Vitamins were originally vitamines: the Polish-born biochemist Casimir Funk who introduced them to the world in 1920 believed that they were amino acids and so formed the name from Latin vita ‘life’ and amine. It was soon discovered that Funk’s belief was mistaken, and alternative names were suggested, but in 1920 it was successfully proposed (by J.C. Drummond) that the -e be dropped to avoid confusion, and the form vitamin was born.
=> amine, vital - vitamin (n.)
- 1920, originally vitamine (1912) coined by Polish biochemist Casimir Funk (1884-1967), from Latin vita "life" (see vital) + amine, because they were thought to contain amino acids. The terminal -e formally was stripped off when scientists learned the true nature of the substance; -in was acceptable because it was used for neutral substances of undefined composition. The lettering system of nomenclature (Vitamin A, B, C, etc.) was introduced at the same time (1920).
