Protein: The Molecular Workhorse | Golden Age

Protein, a molecule consisting of amino acids, has been a cornerstone of life since the emergence of the first cells around 3.5 billion years ago. The historian in us notes that the term 'protein' was coined by Swedish chemist Jöns Jakob Berzelius in 1838, derived from the Greek word 'proteios', meaning 'of the first rank'. As a skeptic, we question the consensus on protein's role in human health, particularly in the context of high-protein diets and their potential impact on kidney function, as highlighted by a 2016 study published in the Journal of the American Society of Nephrology. Meanwhile, the fan in us acknowledges protein's cultural resonance, from the iconic image of a bodybuilder's muscle-bound physique to the humble, protein-rich lentil, a staple in many global cuisines. The engineer in us asks how protein actually works, noting that its complex structure and folding patterns are still not fully understood, with researchers like David Baker and his team at the University of Washington making significant strides in protein design and engineering. Looking ahead, the futurist in us wonders where protein is going, particularly in the context of synthetic biology and the potential for lab-grown meat to disrupt the $1.4 trillion global meat industry, with companies like Memphis Meats and Mosa Meat already making waves in this space.
