Conceptual Questions Answering all thirteen questions (two skipped: #11 “Why do β-sheets aggregate?” merged into #10, and one implicit skip).
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)
Protein makes up ~20% of meat by mass: 500 g × 0.20 = 100 g of protein 100 Daltons = 1.66 × 10⁻²² g per molecule 100 g ÷ (1.66 × 10⁻²² g/molecule) = ~6 × 10²³ molecules (approximately one Avogadro’s number) 2. Why do humans eat beef but do not become a cow, eat fish but do not become fish?</description><generator>Hugo</generator><language>en</language><atom:link href="https://pages.htgaa.org/2026a/zarias-arman-aelius-saadatkhah/homework/week-04-hw-protein-design-part-i/index.xml" rel="self" type="application/rss+xml"/></channel></rss>
