General description
类胡萝卜素是用于食品、动物饲料、保健品和制药行业的天然产品。α- 胡萝卜素，一种具有一个 β-环和一个 ε-环的类胡萝卜素， 普遍存在于食物中。橙色胡萝卜显示出高浓度的 α-胡萝卜素。
Application
α-胡萝卜素可作为标准品，用于使用高效液相色谱(HPLC)为 谷氨酸棒杆菌中类胡萝卜素定量。
Biochem/physiol Actions
α-胡萝卜素表现出维生素A原的活性。它可以作为比 β-胡萝卜素更有效的抑制剂，用于某些生长因子，如N-myc活性。α-胡萝卜素是水果和蔬菜摄入的良好生物标志物。高血清 α-胡萝卜素浓度与较低的心血管疾病(CVD)死亡率相关。

Aim of study was to find the most suitable LC column for generic carotenoid screening. To represent the diversity of carotenoids in nature and to optimize chromatographic separation, a set of carotenoid standards was carefully chosen to account for the

Plasma carotenoid responses were determined in 36 healthy men and women before and after being fed controlled diets with a moderate amount of fat (26% of total energy) and a high carotenoid content (approximately 16 mg/d) for two 15-d periods.
