Conceptual Questions
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) The average molecular weight of an amino acid is ~100 g/mol. In 500 g of meat (if we consider all meat as amino acids) there are 5 moles, which gives 5 × 6 × 10²³ = 3 × 10²⁴ molecules. However, meat is not entirely protein: protein makes up only about 20% of the mass, i.e., 100 g of protein per 500 g of meat. After protein breakdown, this corresponds to 1 mole of amino acids, that is 6 × 10²³ molecules.</description><generator>Hugo</generator><language>en</language><atom:link href="https://pages.htgaa.org/2026a/mariia-moshchenskaia/homework/week-04-hw-protein-design-part-i/index.xml" rel="self" type="application/rss+xml"/></channel></rss>
