英語單詞

niacin是什么意思

niacin

英 ['na??s?n] 美 ['na??sn]
  • n. [生化] 煙酸;尼克酸

中文詞源


niacin 煙酸

縮寫自nicotinic acid.

英文詞源


niacin (n.)
"pellagra-preventing vitamin in enriched bread," 1942, coined from ni(cotinic) ac(id) + -in (2), chemical suffix; suggested by the American Medical Association as a more commercially viable name than nicotinic acid.
The new name was found to be necessary because some anti-tobacco groups warned against enriched bread because it would foster the cigarette habit. ["Cooperative Consumer," Feb. 28, 1942]
