Cracking Chirality: The Mystery of Mirror Molecules
Вставка
- Опубліковано 5 бер 2024
- "Cracking Chirality" from Chemistry Shorts™ explores how the essential molecules of life, like DNA, RNA, and proteins, acquired their homochiral structures and how magnetic rocks at the bottom of a prebiotic lake, may have set the stage for life as we know it.
In a mirror, our bodies appear symmetrical from the right to the left. But hold one hand on top of the other, rather than palm-to-palm, and you’ll notice that they are not in fact the same; they have a defined right- or left-handedness, or chirality. Look even deeper inside, at the molecular level, and you’ll find that many of the important molecules in our bodies are similarly right or left-handed, and exist in only one form or the other. We call this homochirality.
Chirality is the idea that some molecules come in two mirror-image configurations. Despite having the exact same chemical compositions, their physical structures are different. These left-handed and right-handed molecules can have different properties and functions. Understanding how chiral molecules function differently is essential to chemical synthesis and medicine. But it also holds a curious question about early life: why are the nucleic acids that hold genetic information in all of life right-handed, while the amino acids that they encode left-handed?
In "Cracking Chirality,” two Harvard University scientists, Dimitar Sasselov and Furkan Ozturk, present their exciting new findings: magnetized molecules found at the bottom of lakes on the primordial Earth may be the key to how important biological molecules crystallized and grew, tipping the scales from a 50-50 mixture of molecules to homochiral solutions made up of just one or the other. Their simple experimental setups, growing crystals on tiny magnetized plates, help provide a solution to an essential question about life itself that has plagued scientists for decades.
“Life's polymers from DNA, to RNA, to the proteins, cannot really function if they're a mess of left-handed and right-handed molecules. They have to be clearly homochiral. And you need to do something very special to break that symmetry. It is still a big mystery of how this happened at the origin of life. And our work is trying to answer that question.”
- Dr. Dimitar Sasselov in “Cracking Chirality.”
“Cracking Chirality” is targeted towards high school and college students, and can be used as a starting point for discussions around the chemical origins of life, molecular chirality, electron spin, magnetism, and more.

@@haktansina Teşekkürler, umarım ileride ben de Furkan Öztürk gibi bu videolarda yer alarak tekrardan "Sizi buralarda görmek güzel" dedirtebilirim :)
İyi ki varsınız! 🇹🇷 🎉
Türk gençleri için örnek bir cumhuriyet genci👏🏾👏🏾
Siz iyi ki varsınız sizin gibi gençler iyi ki var😊
Sen de iyiki varsın Hocam:)
Muazzam🤍❤️
Helal olsun
Türk gençlerini araştırırken, üretirken görmek bir Türk genci olarak bana çok ilham veriyor bu yüzden size çok teşekkür ederim! Ayrıca belgesel de çok başarılı, tebrikler :)
Kesinlikle bende türk gençlerinin bir turk genci olarak bilim yapmasına ve araştırma yapmasından son derece memnunum ben de aynı şekilde bu kanaldaki olan hesaplamalı evrenle alakalı videoyu izledikten sonra bir bilgisayar bilimi öğrencisi olarak ileride fizik doktorası düşünüyorum ileride çünkü bilgisayar bilimi ve fiziğin birleşimi çok ilgimi çekiyor feynman turing von neumannları okuyunca bu alan çok ilgimi çekti benim de kısaca hikayem öyle:)
We're so glad you liked it!
Go back where you came from. We don't want you here
her türlü yakıyom sigara
It was inspiring for Turkish scientist candidates. Thank you Furkan
We're so glad you liked it!
Love you all ❤
This whole video is excellent, but I must say that the researcher climbing the stairs while spinning at the end was particularly delightful.
Thank you! We like that part too :)
Not only a good scientist he is a good storyteller
We agree! :)
Sevdiği şeylerle uğraşan insanın yüzündeki o mutluluk ,Furkan abide ben bunu görüyorum ve gerçekten bu çok özel yolun açık olsun...
Thank you for watching!

100 years ago, Mustafa Kemal Atatürk, the founder of the Republic of Turkey, showed how much he cared about education by organizing an education congress with teachers despite the war during the War of Independence. Furkan Öztürk has brought pride and honor to Atatürk's humble body with the work he has done today. Thank you, brother Furkan.☺️🙏🏻

@@SFurkanOzturk61 abi başarılarının devamını dilerim. Sana bir soru sormak istiyorum. Benim İngilizcem A1 bile değil öğrenmeye başlamak istiyorum ama nasıl başlayacağımı çözemiyorum. Sence ilk nasıl başlamalıyım?
Şimdiden teşekkür ederim. 😊🙏
Thank you for watching!
All humanity should be proud of you for fulfilling the words of the Great Leader Mustafa Kemal ATATÜRK: "I love the young people who see beyond the horizon, not the horizon." Thank you very much. 🙏🙏
Felsefeci Robert P. Crease'ın 2019'da yazdığı ve Atatürk'ün de dahil edildiği, "Bilim Devrimcileri" adlı kitabını herkese önerelim o zaman. ❤😊
The cameraman did a great job, it elevates the story being told. Congratulations.
Our production team is the greatest! Thank you for watching.
Bir Peter Higgs hayranı olduğum doğrudur. Artık Furkan Öztürk hayranlığım da aynı seviyede.
Thank you for watching!

Bilim hayatın ta kendisiyken onu anlaşılmaz kılmak, teknik terimlerle herkesten soyutlaştırıp sadece kendi kitlesi içinde var etmek de bir seçenekken yapılan kıymetli işleri daha anlaşılır kılmak için gayet komplike olan şeyleri basitleştirmek ona asıl hizmet eden ve aslında en zor olan şey. Bunu başardınız. Dimitar Sasselov, Chemistry Shorts ve Furkan Öztürk Hepinizi tebrik ederim. 👏🏻 Görseller, müzikler, anlatım şahaneydi. Eminim her kitle kendini bu büyülü dünyayı merak ederken ve anlamlandırabildiğini görüp sevinirken bulacak. Furkan’ın heyecanını ve mutluluğunu paylaşıyoruz. 🇹🇷Gurur duyduk bir kez daha 🤍🥹
Narcissus’un hikayesini yorumlayış biçimine ve bu belgesele bağlayışına bayıldım bu arada 😁
We appreciate your comments! Thank you for watching.
When you get the Nobel Prize in the future, the whole world will be proud of you.👏🏽
We can't wait for that :)
Yorumlarda furkan abinin ne kadar çok insana ilham verdiğini görmek çok güzel
Thank you for watching!
Bizim üniversitelerde olmayan şey bir astrofizikcinin moleküller biyolojiye girmesidir, farklı alanlardaki bilgi birikiminin yararlı olabileceği her zaman hesaba katılmalıdır, sadece bu yaklaşıma sahip olmanız, oradaki bilim insanlarının bunu desteklemesi bile takdire değerdir. Örnek almalıyız.
Thank you for watching!
We are here as the students of Furkan 🇹🇷
We're so glad to have you here!
Go back to mongolia

Keşke bu tür bilimsel çalışmalar ve projeler daha da yaygınlaşsa.Ülkece gereksiz şahısları takip edip onları fenomen yapmaktansa bu tür bilim insanlarını ileriye taşımayı yeğlerim.Bilmem anlatabildimmi.Furkan Türkiyenin örnek bir insanı olduğun için sana minnettarım.
Benim gibi gençlere esin kaynağı oldun.Biz Türk gençlerinin en çok da benim böyle bir emsale ihtiyacımız vardı.❤
Thank you for watching!
This is groundbreaking. This is such a large piece of the puzzle and yet confirms whats I understand to be true. There’s a medium by way of "scaffolding" rather than specific elements that create what we see. This might also explain the stimuli that the living dervives from its environments such as one would seek a reflection. I mean by way of connecting why we adapt to what we respond to in our environments and the casual link between us the macro and particle influence and orientation, which would be micro
You have answered a question that has been eating at me since my freshman year at UC Boulder, over 40 years ago.
Wow! Glad we could help :)
As a Turkish chemist, I am beyond proud of Furkan Ozturk👏🏻

Milli gururlarımızdan biri, Tebrikler Furkan!
Thank you for watching!
Super - truly conclusive experimental demonstration; a joy to watch. May I mention that a few years ago I had the fortune to see a crescent moon just after sunset with Venus very close in the picture. As the sky darkened to night I noticed the shadowed part of the moon was actually visible(!) because of illumination from sunlight reflected off planet Earth (I learned about Earth-shine). It was a revelation - suddenly I saw the whole night sky in its true 3d perspective.
Thank you for sharing that with us! We're glad you liked the video.
Sevgili Furkan hocam, sen yaptıklarınla gençlerimize harika bir örnek oluyorsun. Başarılarının devamını diliyor ve yeni paylaşımlarını dört gözle bekliyorum. 👏

Thank you for wonderful expression🇹🇷
Thank you for watching!
please include me in your study..... such positive work atmosphere, no academic pressure nothing to worry about just pure science and curiosity
Really thanks for sharing this incredible background of the scientists...more away from the so interesting research in Origin of life-prebiotic chemistry- Chirality...I felt so connect with Sasselov, since he himself said he would never had thought to be studying chemistry since he had ever hated it...I'm in almosttttt a same situation with a difference...I love Chemistry, also Astronomy and Biology and I've been feeling pressure just for having to choose one to start a scientific carrer if I want to get closer to one of my dreams ...study in a field that link these beautiful areas can be possible while doing it just following what I like, without prejudices or "ideals" of what I should do/follow... ❤
Dr. Sasselov is so inspiring! We're glad you liked the video.
I was not expecting to see Furkan in a chemistry related channel, even though I knew about his origin works. So exciting! Physics people unite! Lol
Welcome to our channel! :)
Maybe he wanna say chemical researchers and physicians need to cooperation with some projects together.
This important work deserves Nobel prize. 👌
We are all proud of your success dear Furkan Ozturk. Regards to you
