— Q1: 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)
First, we need to calculate the number of moles and multiply by Avogadro’s number (NA=6.022×1023 mol−1). An amino acid has an average mass of ~100 Daltons (Da), which is roughly equivalent to 100 g/mol. Meat is mostly protein (~20% of its weight is protein). → 500 g of meat contains approximately 100 g of protein. Since 1 mole of amino acids weighs ~100 g, there are ~1 mole of amino acids in 100 g of protein. → 1 mole is equivalent to 6.022 × 1023 molecules (Avogadro’s number). So you consume approximately 6 × 1023 amino acids in 500 g of meat.</description><generator>Hugo</generator><language>en</language><atom:link href="https://pages.htgaa.org/2026a/violeta-vilcapoma-torres/homework/week-4-protein-design-part-i/index.xml" rel="self" type="application/rss+xml"/></channel></rss>
