现代理论认为，人体的慢性衰老和化学损伤都是从氧化应激开始的。人体内的氧化压力和抗氧化能力失衡，会造成分子和细胞层面损伤，进而发展到代谢失衡、机能障碍和物理结构不可逆损伤。

人体内的抗氧化系统主要由两部分组成，即抗氧化酶系和非酶抗氧化剂。非酶抗氧化剂有很多人们熟悉的成员，如维生素C、维生素E、β-胡萝卜素、辅酶Q10、花青素等;而抗氧化酶系主要有超氧化物歧化酶(SOD)、过氧化氢酶(CAT)和谷胱甘肽过氧化物酶(GPX)。而目前已知的GPX有6种不同类型，根据基因库命名排序，分别被命名为GPX-1、2、3、4、5、6，其中GPX-5的活性中心是半胱氨酸，不属于硒酶，其余5种GPX的活性中心是硒半胱氨酸，硒是其必要组成成分。显而易见的是，硒在人体内的水平会直接影响甚至决定GPX的数量和活性。人体的五脏六腑特别是呼吸系统、消化道等直接与外界相通，面临的来自食物、空气等的氧化压力是最大的，如果缺乏硒（甘氨酸硒Selenium Glycinate、大米肽硒Selenium Rice-Peptides），特别是长期摄入不足，GPX浓度下降，就会最先出现抗氧化失衡，势必会诱发相应的损伤和细胞坏死。

Selenium (Selenium Glycinate, Selenium Rice-Peptides): Key elements of the human antioxidant system

Modern theory believes that chronic aging and chemical damage to the human body start from oxidative stress. The imbalance of oxidative stress and antioxidant capacity in the human body will cause damage at the molecular and cellular levels, and then develop into metabolic imbalance, dysfunction and irreversible damage to physical structure.

The antioxidant system in the human body is mainly composed of two parts, namely antioxidant enzymes and non-enzymatic antioxidants. There are many familiar members of non-enzymatic antioxidants, such as vitamin C, vitamin E, β-carotene, coenzyme Q10, anthocyanins, etc.; while the antioxidant enzyme system mainly includes superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX). There are currently 6 different types of GPX known, which are named GPX-1, 2, 3, 4, 5, and 6 according to the naming order of the gene bank. The active center of GPX-5 is cysteine, which is not a selenoenzyme. The active centers of the other 5 GPX are selenocysteine, and selenium is its necessary component. Obviously, the level of selenium in the human body will directly affect or even determine the number and activity of GPX. The internal organs of the human body, especially the respiratory system and digestive tract, are directly connected to the outside world, and face the greatest oxidative pressure from food, air, etc. If there is a lack of selenium (Selenium Glycinate, Selenium Rice-Peptides), especially long-term insufficient intake, the GPX concentration will decrease, and the antioxidant imbalance will appear first, which will inevitably induce corresponding damage and cell necrosis.
