锗是一种稀散金属,它具有金属和非金属的双重性质。锗广泛分布在自然界中,一些植物如灵芝、人参、大蒜、蘑菇中含量较高。人们日常食用的海产品、蔬菜、谷物、奶制品中也不同程度地含有锗。锗的化合物分为无机锗和有机锗两种。无机锗即无机氧化锗,(GeO_2),毒性大,不能用于人体。有机锗现已合成了1000多种化合物。在我国使用的β—羧乙基锗倍半氧化物(Ge—132)和赖氨酸锗化合物(Ge—401和Ge—201)。通常所说的有机锗
Germanium is a rare-earth metal that has the dual nature of metals and non-metals. Germanium is widely distributed in nature, some plants such as Ganoderma lucidum, ginseng, garlic, mushrooms higher levels. People’s daily consumption of seafood, vegetables, cereals, dairy products also contain different levels of germanium. Germanium compounds are divided into two kinds of inorganic germanium and organic germanium. Inorganic germanium inorganic germanium oxide, (GeO_2), toxic, can not be used in the human body. Organic germanium has now synthesized more than 1,000 kinds of compounds. Β-carboxyethylgermanium sesquioxide (Ge-132) and lysine-germanium compounds (Ge-401 and Ge-201) used in our country. Commonly referred to as organic germanium
