蛋白质分子(proteinmolecule)
由单肽链聚合成的多肽链。它可由次级键作用形成α-螺旋、β-折叠及无规卷曲等多种复杂的空间结构。蛋白质分子量巨大,约在103~1012道尔顿之间,具有旋光、UV吸收光学性质、电学性质和两性本质,并有特异的颜色反应。中性盐、醇、酸、重金属盐和生物碱试剂,在一定条件下能使蛋白质沉淀。各种化学和物理因素均可能破坏氢键及其他弱键而导致蛋白质失去活性。重要的结合蛋白质有糖蛋白、脂蛋白、色蛋白和核蛋白。蛋白质由细胞内的核糖蛋白体按照核酸上DNA序列的“遗传密码”翻译制造出来。蛋白质是一切生命体必不可少的物质组分之一,人体中约有19是蛋白质,它具有多种生物功能,是生命活动的重要基础物质。
