微量元素在围产期的代谢特点和作用: 一、锌:是动物和人体必需的微量元素,作为金属酶和激素的成分参与各种类型的物质代谢。在细胞膜的分化和稳定上,在生物活性物质代谢和许多其他代谢过程中都有重要作用。锌的代谢取决于许多因素,诸如营养特点,肠的吸收,器官组织内的分布,激素的调节,同化和异化过程的比例,肾脏的排出,遗传因素和围产期发育特点等。临床研究表明:正常妊娠妇女从第二个月起血锌水平随妊娠期增长而下降,多数下降的原因是胎儿微量元素需要增加。正常足
Trace elements in the perinatal metabolic characteristics and roles: First, zinc: animal and human essential trace elements, as a metal enzyme and hormone components involved in various types of material metabolism. In the cell membrane differentiation and stability, in the metabolism of bioactive substances and many other metabolic processes have an important role. Metabolism of zinc depends on many factors such as nourishment characteristics, intestinal absorption, distribution within organs and tissues, regulation of hormones, proportion of anabolic and alienation processes, renal excretion, genetic factors and perinatal developmental characteristics. Clinical studies have shown that: normal pregnant women from the second month of zinc blood levels decreased with the increase of pregnancy, the majority of the decline is due to fetal fetal elements need to increase.
