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)
R/: Meat is approximately 20% protein by mass, so 500g of meat contains roughly 100g of protein. Since the average amino acid has a molecular weight of ~100 Daltons (100 g/mol), 100g of protein equals 1 mole of amino acids. Multiplying by Avogadro’s number gives approximately 6 × 10²³ molecules = 600 sextillion amino acid molecules in a single piece of meat.</description><generator>Hugo</generator><language>en</language><atom:link href="https://pages.htgaa.org/2026a/maria-jose-bolivar/homework/week-04-hw-protein-design-part-i/index.xml" rel="self" type="application/rss+xml"/></channel></rss>
