Conceptual Questions
1. 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)
There are a variety of meats depending on the kind. Let’s take an average of about 20% of protein by mass of meat (Day, 2016). This would therefore mean that 500g of meat would contain roughly 100g of protein. The average molecular weight of an amino acid residue is 100 Daltons, which translates to about 100g per mole of the amino acid unit (100g/100g/mol = 1 mole of amino acid units) (ProPrep, 2019). 1 mole contains 6.022 x 10^23 (Avogadro’s number) amount of particles (The ChemTeam, 2026). Therefore, if you consume 500g of meat, you are also ingesting approximately 6 x 10^23 amino acid residues.</description><generator>Hugo</generator><language>en</language><atom:link href="https://pages.htgaa.org/2026a/justine-de-riedmatten/homework/week-04-hw-protein-design-parti-i/index.xml" rel="self" type="application/rss+xml"/></channel></rss>
