查询词典 carotenoid

Vulgaris to magnetic treatment The Superoxide anion in algae cell increased and antioxidant ability was declined by a suitable magnetic treatment. There was different response of the enzymic component-Superoxide dismutase , Catalase , and peroxidase enzyme, and their activities were induced to increase. There was no much response for the nonenzymic component-glutatnione to the magnetic treatment, while content of carotenoid was reduced remarkably with the increasing magnetic intensity and time.

小球藻抗氧化系统对磁处理的响应一定强度的磁处理使小球藻中超氧阴离子·O〓升高，抗氧化能力降低，抗氧化酶系统的关键酶SOD，CAT，POD酶应激性升高；非酶体系的GSH对磁处理响应不明显，Caro含量普遍有较为明显的降低，随处理时间的增加Caro的量下降显著。

［目的］探讨微波萃取法提取橘皮中类胡萝卜素的工艺条件。

The results show that the ratios of chlorophyll to carotenoid, purpurin and red pigment for four maize genotypes decrease under low P dose. Those of "7922" and "Ye107" are 0.4~0.8 times those under high P dose, with much higher decrease than in "178" and "(superscript *)082".

结果表明，低磷条件下，玉米叶片叶绿素／类胡萝卜素、叶绿素／紫色素和叶绿素／红色素均减少，其中基因型"7922"和"掖107"的叶绿素／类胡萝卜素、叶绿素／紫色素和叶绿素／红色素减少幅度较大，为高磷条件下的0.4~0.8倍，且减少幅度高于"178"和"082"。

Total sugar of sarcocarp and chlorophyll of pericarp increased firstly, and then decreased afterward along with altitude; Titratable acidity, ascorbicacid and anthocyanin of pericarp were increased along with altitude; The content of protein increased firstly and decreased afterward along with altitude; Carotenoid of pericarp were decreased along with altitude.

果肉总糖和果皮叶绿素含量随海拔高度升高先升高后降低；可滴定酸、维生素C和果皮花青苷含量均随海拔升高而升高；蛋白质在1720m处最大，1420m处最小；果皮类胡萝卜素随海拔升高而降低。

He noted that an enzyme in the human pathway, squalene synthase, was strikingly similar to one that led to the production of the carotenoid in Staph.

他指出，在人体通路中的一种酶，即角鲨烯合酶，与葡萄球菌生产类胡萝卜素过程中的一种酶有惊人的相似之处。

Uses: Lutein, and its naturally occurring stereoisomer zeaxanthin, is used as part of a general carotenoid defense against oxidative stress, whether solar or metabolic.

用途： 叶黄素和其立体异构体玉米黄质，作为常规类胡萝卜素的一部分，用于防止来自日光的或者来自新陈代谢的氧化压力。

ABSTRACT Fruit ripening is associated with a number of physiological and biochemical changes including degradation of chlorophyll, carotenoid biosynthesis, synthesis of flavor compounds, conversion of starch to sugars, cell wall solublisation and fruit softening.

果实的发育成熟涉及一系列复杂的生理生化变化，包括叶绿素的降解、类胡萝卜素的合成、淀粉向糖的转化、芳香性化合物的合成、细胞壁溶解和果实软化等。

Results The UV-B treatment caused the declines of chlorophyll content, soluble protein content and water content of leaves, besides, dose-effect was existed. The decline of 30 μW/cm^2 treatment was bigger than that of 15 μW/cm^2 treatment. The influences of UV-B radiation on carotenoid content and anthocyanidin content were similar; the change trends were declined firstly then increased. The UV-B treatment with two doses restrained the electron transport of PSⅡ, particularly; the inhibitory effect was biggest after treated 2h, and then this effect was declined in 4, 6 and 8 h, so the dose-effect was existed. The UV-B radiation with two doses restricted photosynthetic rate and the inhibitory effect increased with the increase of treatment time. The high dose treatment caused huge damage to membrane system, while the result of low dose treatment was not obvious.

结果］UV-B处理导致叶绿素、可溶性蛋白含量以及含水量都降低，且存在剂量效应，30μW/平方公分处理的降幅大于15μW/平方公分；UV-B辐射处理对类胡萝卜素含量的影响与花青素相同，均表现为先下降后上升的趋势，2种剂量间差异不大；2种剂量的UV-B处理均抑制了PSⅡ的电子传递，尤其是处理2 h的抑制作用最大，4、6和8 h的抑制作用有所缓解，且存在剂量效应；2种剂量的UV-B辐射均抑制了叶片的光合速率，随着照射时间的延长抑制效应加大；高剂量UV-B处理对膜系统的损伤较大，低剂量UV-B处理结果不明显。

The contents of chl, chla and chlb of Celtis julianae 'Aurea' decreased at the same time and were lower than that of Celtis julianae . Although the carotenoid content was little lower, during degreening and regreening process, its content increased continuously.

金叶珊瑚朴的chl、chla和chlb的变化趋势一致，均显著低于珊瑚朴；类胡萝卜素的含量虽稍低于珊瑚朴，但在叶色变化中，持续升高，因此，金叶珊瑚朴属于总叶绿素缺陷型。
