General description
松果菊酮是一种具有共轭羰基的类胡萝卜素。松果菊酮（4-酮-β-胡萝卜素）是一种单酮化合物，是动物中的 β-胡萝卜素和角黄素的中间体。它是鱼腥藻的主要类胡萝卜素之一，也存在于玫瑰微球菌中。它位于 鱼腥藻的类囊体膜上 。β-胡萝卜素转化为海胆酮是由β-胡萝卜素酮酶CrtO催化的。
Application
松果菊酮可作为外部血浆样品中类胡萝卜素的外标。也可用作内标物，加入样品中用于提取和定量。
Biochem/physiol Actions
松果菊酮与球藻视紫红质结合，在 紫花地丁 中作为光捕获天线发挥作用。

The photoactive orange carotenoid protein (OCP) is a blue-light intensity sensor involved in cyanobacterial photoprotection. Three OCP families co-exist (OCPX, OCP1 and OCP2), having originated from the fusion of ancestral domain genes. Here, we report the characterization of an OCPX

Proteorhodopsins are light-driven proton pumps that occur widespread in Nature, where they function predominantly in environments with high incident irradiance. Their maximal absorbance is usually in the blue range, but can be extended into the (far)red range of the electromagnetic

The mechanisms of main tomato carotenes (phytoene, phytofluene, lycopene and β-carotene) intestinal absorption are still only partly understood. We thus compared carotene bioavailability in mice after gavage with carotene-rich oil-in-water emulsions. We also determined each carotene absorption profile along the
