Copper (Cu) is an essential trace element for humans and animals. Copper is found in a wide variety of foods and is most plentiful in organ meats, shellfish, nuts, and seeds. Wheat-bran cereals and whole-grain products are also good sources of copper. Copper is a critical functional component of several essential enzymes known as cuproenzymes. Some of the physiologic functions copper is involved in are energy production, iron metabolism and proper functioning of the central nervous system. Copper also plays a role as an antioxidant as part of superoxide dismutase. (LPI)
铜
铜(Cu)是人和动物必需的微量元素。铜储存在多种食物,而在动物内脏,贝壳类,坚果和种子中的含量最充足。小麦麸谷物和全麦产品也是摄取铜的良好来源。铜被称为铜酶,是一部分关键酶的重要功能组件。一些生理功能铜参与人体中能源生产,铁代谢和中枢神经系统的正常运转。铜同时作为抗氧化剂如超氧化物歧化酶的一部分,也起着重要的作用(LPI)
Vitamin C
Vitamin C is an essential water soluble vitamin. Humans are amongst the few mammals that cannot produce vitamin C intrinsically and as a result must obtain it from their diet. Vitamin C is available in many different forms including ascorbic acid, mineral ascorbates such as calcium ascorbate, and ascorbyl palmitate a fat soluble form. Vitamin C is an antioxidant, protecting the body against oxidative stress caused by free radicals and reactive oxygen species. It is also a cofactor in at least eight enzymatic reactions. Vitamin C is needed for the production of collagen a component of connective tissue. These fibres are in many places throughout the body; providing firm but flexible structure. Some tissues have a greater percentage of collagen, especially: skin, mucous membranes, teeth, and bones. Vitamin C is required for making of dopamine, noradrenaline, and adrenaline in the nervous system or in the adrenal glands. Vitamin C is also needed to make carnitine, important in the transport of fatty acids into cell mitochondria for energy production.
维生素C
维生素C是一种人体必需的水溶性维生素。人类是哺乳动物当间极少数不能自身产生维生素C的物种,因此必须从饮食中获取它的。维生素C有许多种不同的存在形式,包括以抗坏血酸,抗坏血酸无机盐例如抗坏血酸钙,以及抗坏血酸棕榈酸酯脂溶性的形式提供。维生素C也是一种抗氧化剂,能够保护身体,免受由自由基和活性氧类带来的氧化应激。它是至少八个酶促反应中的辅助因子。维生素C为胶原结缔组织的组分的生产提供了必需的成分。这些纤维分布整个身体的各个成分;提供坚固并且有弹性的结构。当中的一些组织含有胶原蛋白并且占有有较大的比例:分别分布在皮肤,粘膜,牙齿和骨骼上。维生素C是制造在神经系统中或在肾上腺内的多巴胺,去甲肾上腺素和肾上腺素的必需品。维生素C同时也是制造肉碱的必需品,在脂肪酸进入细胞线粒体的运输中具有重要的作用,人体以此产生能量。更多精彩文章及讨论,请光临枫下论坛 rolia.net
