硒(甘氨酸硒Selenium Glycinate、大米肽硒Selenium Rice-Peptides):人體抗氧化系統(tǒng)的關(guān)鍵元素發(fā)表時間:2024-11-18 19:21 現(xiàn)代理論認為,人體的慢性衰老和化學(xué)損傷都是從氧化應(yīng)激開始的。人體內(nèi)的氧化壓力和抗氧化能力失衡,會造成分子和細胞層面損傷,進而發(fā)展到代謝失衡、機能障礙和物理結(jié)構(gòu)不可逆損傷。 人體內(nèi)的抗氧化系統(tǒng)主要由兩部分組成,即抗氧化酶系和非酶抗氧化劑。非酶抗氧化劑有很多人們熟悉的成員,如維生素C、維生素E、β-胡蘿卜素、輔酶Q10、花青素等;而抗氧化酶系主要有超氧化物歧化酶(SOD)、過氧化氫酶(CAT)和谷胱甘肽過氧化物酶(GPX)。而目前已知的GPX有6種不同類型,根據(jù)基因庫命名排序,分別被命名為GPX-1、2、3、4、5、6,其中GPX-5的活性中心是半胱氨酸,不屬于硒酶,其余5種GPX的活性中心是硒半胱氨酸,硒是其必要組成成分。顯而易見的是,硒在人體內(nèi)的水平會直接影響甚至決定GPX的數(shù)量和活性。人體的五臟六腑特別是呼吸系統(tǒng)、消化道等直接與外界相通,面臨的來自食物、空氣等的氧化壓力是最大的,如果缺乏硒(甘氨酸硒Selenium Glycinate、大米肽硒Selenium Rice-Peptides),特別是長期攝入不足,GPX濃度下降,就會最先出現(xiàn)抗氧化失衡,勢必會誘發(fā)相應(yīng)的損傷和細胞壞死。

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.
