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)
A Dalton (Da), also known as an atomic mass unit, is a unit of mass that can be converted into grams (1 Dalton = 1 g/mol). To calculate the number of amino acid molecules, we first need the protein content. Assuming an average protein content in meat of approximately 22%, a 500-gram piece of meat contains about 110 grams of protein. Since 1 Dalton equals roughly 1.6605 × 10⁻²⁴ grams, and an average amino acid is 100 Da, a single amino acid molecule weighs approximately 1.66 × 10⁻²² grams. Therefore, the number of amino acid molecules in that meat is 110 grams divided by 1.66 × 10⁻²² grams, which is approximately 6.62 × 10²³ molecules.</description><generator>Hugo</generator><language>en</language><atom:link href="https://pages.htgaa.org/2026a/karol-duque/homework/week-04-hw-protein-design-part-i/index.xml" rel="self" type="application/rss+xml"/></channel></rss>
