1.吸收:一个70公斤的人含12～20毫克锰。成人每天摄入锰0.7～22.0毫克左右,与各地区的饮食有关。坚果、谷物含锰最高,动物性食品含量低,咖啡及茶含量也高。人乳是缺锰的。婴儿出生后一周,锰摄入仅7微克/天,产生负锰平衡。以后摄入逐渐增加,直到二岁。尽管如此,从新生儿开始,人一生中肝脏的锰含量一直是恒定的。婴儿如何获得锰,什么部位储藏,还不清楚。吸收后的锰与球蛋白结合,称为“转锰蛋白”,是一种特殊的携带锰的血浆蛋白。一个锰原子可结合一个以上球蛋白分子。
1. Absorption: a 70 kg containing 12 to 20 mg of manganese. Adult daily intake of manganese 0.7 ~ 22.0 mg or so, with the diet of all regions. Nuts, grains contain the highest manganese content, animal food content is low, coffee and tea content is also high. Human milk is manganese deficiency. One week after the baby was born, manganese intake was only 7 micrograms / day, resulting in a negative manganese balance. After the intake gradually increased until the age of two. However, the liver’s manganese content has been constant throughout the life of a newborn. How babies get manganese, what part of the storage, it is not clear. After absorption of manganese and globulin binding, known as “manganese”, is a special manganese-carrying plasma protein. A manganese atom can bind more than one globulin molecule.
