已知氨基酸平均分子质量还有蛋白质相对分子量级脱水质量如何确定蛋白质肽数

氨基酸平均分子质量是128若某蛋白质相对分子量为10228形成改蛋白质时脱水质量量为1548求该蛋白质肽链数

Answer 1

由已知脱去1548/18=86个水分子，有86个肽键，氨基酸的总分子量为10228+1548=11776,于是有氨基酸11776/128=92个，再用它减去肽键数，肽链数为92-86=6.

Answer 2

蛋白质相对分子质量=氨基酸平均分子质量*N--18*肽键数
你这题目氨基酸数 肽链数得至少已知一个才能求的

Master of the Moon on the Earth will encounter unexpected difficulties. First of all, the moon is the Earth's gravity 1/6 people up, first of all feel super cool, walking is easy, it feels like time slows down as slowly in order to jump to the ground, human beings must adapt to this gravity also after training at the Earth. Secondly, thin air on the moon, mankind in order to breathe, must wear spacesuits. Also, the pressure on the Moon and Earth are not the same, if they are directly exposed to the moon, will be the body's pressure burst pressure; because there is no air on the moon, and turnover is around the Earth, the temperature difference is very large, not to mention human beings, is the ordinary when the machine also can not stand the feeling of hot and cold; there is no air on the moon, solar radiation and cosmic rays directly onto the human body, the human cell structure damage, accelerated aging, cancer of; there is no air on the moon, the outer stray meteorite directly hits the lunar surface, the impact worse than bullets will hit you at any time.
