Application
虾青素已被用于：
- 作为抗氧化剂来研究其对臂尾轮虫（Brachionus manjavacas）（轮虫纲）种群生长的影响
- 研究其对糖尿病性视网膜病变治疗的影响。
- 通过人前列腺 LNCaP 细胞的表观遗传修饰，研究其在恢复 Nrf2（核因子红细胞 2 p45 相关因子 2）和谷胱甘肽 S-转移酶 P1（GSTP1）表达中的作用。
Biochem/physiol Actions
体内和体外研究提出虾青素（AST）具有促进健康的活性，表明其可用于预防多种疾病，例如癌症和帕金森病。由于其颜色鲜红，AST 已用作动物饲料中的食用色素。
虾青素是一种有效的抗氧化剂，具有抗增殖、神经保护和抗炎作用。
虾青素是一种有效的抗氧化剂，具有抗增殖、神经保护和抗炎作用。 虾青素可防止氧化应激，抑制 NF-KB，抑制促炎基因，抑制促炎化合物一氧化氮、前列腺素 E2、TNF-α 和白细胞介素-1β 的产生。 虾青素′对 TNF-α 和棕榈酸产生的氧化应激的保护作用已被证明可以改善胰岛素抵抗。 虾青素也被证明是 PPARγ 的抑制剂。
General description
虾青素（AST）是一种红色的膳食类胡萝卜素。它主要存在于水生动物和微藻中，如雨生红球藻（Haematococcus pluvialis）和小球藻（Chlorella zofingiensis）。
