How many molecules of amino acids do you take with a piece of 500 grams of meat? (on average an amino acid is ~100 Daltons)
Meat contains ~20% protein (Kenneth Carpenter et al. Britannica, 2026). In 500 grams of meat, ~100 grams is protein. That is equivalent to 100 grams of amino acids. By the mol formula, the number of mols of amino acids = Mass/RMM = 100 grams/100 Daltons = 100 grams/100 gram mol^-1 = 1 mol Therefore, number of molecules = Number of mols x Avogadro’s Number = 1 mol x 6.02214076×1023 mol−1 = 6.02214076×10^23 Hence, 6.02214076×10^23 molecules of amino acid are present in 500 grams of meat. 2. Why do humans eat beef but do not become a cow, eat fish but do not become fish?</description><generator>Hugo</generator><language>en</language><atom:link href="https://pages.htgaa.org/2026a/samriddh-sadhukhan/homework/week-04-hw-protein-design-part-i/index.xml" rel="self" type="application/rss+xml"/></channel></rss>
