basic origins of the word “vitamin.” 1.Name AND draw the functional group related to the topic of the basic origins of the word “vitamin.” Also, find a vitamin that 'meats' the criteria of the original implications of the word; give the common and/or IUPAC name of it, and draw it, if feasible. Vitamin can be looked upon as a combination of “vita” (life) and “amin” (amine). It was mistakenly thought that all vitamins contained and amine (NH2) group. The structure of thiamine (vitamin B1 or 2-[3-[(4-amino-2-methyl- pyrimidin-5-yl)methyl]- 4-methyl-thiazol-5-yl] ethanol) is shown at http://en.wikipedia.org/wiki/Thiamine. amine is the functional group?? Thiamine is the vitamin that meets the criteria?
