(On average, an amino acid is ~100 Daltons.) Depending on the type of meat, as well as the manner it is processed prior to consumption, 500g of meat contain approximately 100 - 130g of protein. Assuming that this protein consists entirely of amino acids (meaning, excluding metal ions, such as iron or zinc, which can be found bound to protein molecules, or glycans and other moieties added to proteins through post-translational modifications), then 100-130g of amino acids = 6.02 - 7.83x1025Da approximately. Therefore, if the molecular weight of one amino acid is on average ~100Da, then 500g of meat contain (6.02 - 7.83x1025Da)/100Da = 6.02 - 7.83x1023 amino acid molecules.</description><generator>Hugo</generator><language>en</language><atom:link href="https://pages.htgaa.org/2026a/sofia-oikonomou/homework/week-04-hw-protein-design-part-i/index.xml" rel="self" type="application/rss+xml"/></channel></rss>
