「世界之最」肌联蛋白

Titin（肌联蛋白）是目前已知的最大的蛋白质，它的分子量为2700kDa（25,000多个氨基端），长度为1μm，约占肌节的一半，是高度弹性分子。

根据IUPAC（国际理论和应用化学联合会）命名规则，该肌联蛋白的名字足足有189819个字母，是世界上字母量最大的单词，快速读完这个单词需要3个多小时。

下面是此单词的英文全称的一部分，简直丧心病狂：

市面上的蛋白粉有名的就那么几个牌子，国外的主要是肌肉科技、欧普特蒙、诺特兰德、美瑞克斯以及广为流传超级便宜的mp熊猫粉，国内主要有汤臣倍健、康比特等，但从蛋白粉的主要作用来说，健身买蛋白粉说白了就是为了获取更优质的蛋白质。市面上销售的蛋白粉主要就是乳清蛋白，其他什么大豆蛋白啊鸡蛋白啊都是噱头，不要被忽悠了，花了乳清蛋白粉的价钱买了大豆蛋白粉。蛋白质可分为动物蛋白与植物蛋白，动物蛋白与人类的营养结构比较吻合，其蛋白质的种类和结构更加接近人体的蛋白结构和数量，而且一般都含有人体必需的8种氨基酸(特别是蛋制品和奶制品)，所以动物蛋白质要比植物蛋白质营养价值高。蛋白粉又分为增肌粉，乳清蛋白粉，和正氮氮白粉，比较常见的三种，瘦子增肌就用增肌粉，微胖增肌的就用乳清蛋白粉，专业增肌就用正氮蛋白

增肌粉主要的含量就是蛋白和碳水， 乳清蛋白就是高蛋白和低脂肪，正氮蛋白就是更高的蛋白和正氮因子。那蛋白粉的选择呢，其中my protein就是公认非常便宜的熊猫粉，毕竟一分钱一分货，每100牛奶才含有07乳清蛋白，蛋白粉的乳清蛋白含量越高意味着成本越高。康比特，欧普特蒙等杂七杂八的差别不大，乳清蛋白的含量虚标，实际含量没那么高，价格也是同类品牌中较贵的，所以性价比不算高。 诺特兰德算是蛋白粉中口感比较好的，肌肉科技选择喝高性能系列的，从吸收效率以及身体去“分梯度吸收”来持续供给蛋白质，会更有效一些比较适合新手。

蛋白质含量高的食物主要有以下4种：

1) 奶类食物以及奶制品，像牛奶，羊奶等其含有大量的蛋白质，不仅可以帮我们补充充足的蛋白质，还含有丰富的钙质，可以有效预防缺钙的情况。

2) 肉类食物，比如猪，羊，牛，鸡，鸭，鹅等各种牲畜的肉类都是含有丰富的蛋白质的。

3) 蛋类食物，鸡蛋可以说是蛋白质含量最高的代表食物，特别是鸡蛋蛋黄的蛋白质含量很高，但是对于鸡蛋的摄入也是需要注意的，由于蛋黄的胆固醇较高，所以一天摄入的鸡蛋最好不要超过两个。

4) 豆类食品，豆类食品中植物蛋白的含量较高，其中黄豆的营养价值是最高的。同时吃豆制品还能降低胆固醇，起到抗癌的作用。

蛋白质是人体的三大营养成分之一，它的功效可以提供人体一些营养，还可以提供人体能量以及热量，有助于提高肌肉的力量速度，特别是对于运动员来讲，或者说对于经常去健身的人来说，练肌肉的话需要补充蛋白质。蛋白质也是人体的结构组织重要的组成部分，我们需要蛋白质。蛋白质还可以补充保持渗透压的作用，比如说失血的病人或者慢性消耗性的病人，这个时候需要补充蛋白质，维持人体的正常的渗透压。
