What is Life Made of? (Carbon & Biological Molecules): Crash Course Biology #20
HTML-код
- Опубликовано: 19 июн 2024
- Despite the diverse appearance and characteristics of organisms on Earth, the chemicals that make up living things are remarkably similar, often identical. In this episode of Crash Course Biology, we’ll look at the building blocks of the four major classes of biomolecules, how those join up to form macromolecules, and how a team of six atoms forms the vast majority of living matter.
Chapters:
Introduction to Life’s Molecules 00:00
Chemical Bonds 2:38
The Major Biological Molecules 6:12
Polymerization 9:27
Hydrolysis 10:54
Review & Credits 12:32

Grown adult in his 30s, and I enjoy watching these because they remind me of PBS science shows from back in the day.
I was today years old when I learned about CHNOPS, and how they integrate into everything.
I am so pleased that you are doing this course. You have an engaging presentation. Thanks.
Dude gives off serious LeVar Burton vibes and I am HERE FOR IT.
I smashed my chemistry class thanks to crashcourse.
Same & that's how I found the channel back in 2014 or 15
I crashed my chemistry course thanks to smash class.
As an old person, apparently, I appreciate the Trogdor reference. Glory to the burninator.
Burninating the countryside
ABSOLUTE BEST series in a while. Well done, Doc !
Love the narrator’s presentation skills and the graphics make learning engaging and fun.
I wish i had resources like this when i was at school. 😢
we all here do
Love it! Thank you!❤
I appreciate all the works u’ve put to the video! Btw could u please let me know what kind of editing program u use making the video? Like premier pro or after effect?
Great video. I love it! Thank you so much.
Informative as always.

📝 Summary of Key Points:
📌 All living organisms share the same chemical building blocks, despite differences in size and complexity.
🧐 The six key elemental players in the game of life are carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur, which form DNA and proteins.
🚀 Carbon is the most common element and forms the basis of organic compounds, creating covalent bonds with other atoms to form organic molecules.
🚀 Oxygen and nitrogen also play important roles in forming different compounds.
🚀 The four major classes of biological molecules are lipids, carbohydrates, proteins, and nucleic acids, which are essential for life.
🚀 These molecules are broken down and synthesized through hydrolysis and dehydration reactions.
💡 Additional Insights and Observations:
💬 "Despite the differences in size and complexity, all organisms share the same chemical building blocks."
📊 No specific data or statistics were mentioned in the video.
🌐 No specific references or sources were mentioned in the video.
📣 Concluding Remarks:
The video highlights the biochemical similarities between all living things, emphasizing the importance of the six key elemental players in the game of life. These elements form the basis of DNA and proteins, and together with other elements, they create the diverse array of organic compounds necessary for life. Understanding these fundamental building blocks helps us appreciate the unity and diversity of all living organisms.
Amazing ❤
as always: a great video!
This guy is awesome!
Woot! Organic chemistry!
I saw that lighter trogdor reference lol
I prefer the CHONPS acronym, it sounds nicer
New video!!
Hi how's it going watching from Broomfield Colorado
some Peppermint CHNOPS plz
Theme music needs more base!
First!!!
Kinda disappointed that you didn't call the team "Sponch". Rolls off the tongue better.
FIRST
Yeah but my question is still unanswered. Why is life made up of some specific elements only. Why is Carbon and oxygen alive but iron and zinc not?
It is because: Carbon atom is the unique atom that can form 4 stable covalent bonds with other carbon atoms and a wide range of other elements, and it can do so in many different ways from rings, to chains, to double or even triple bonds. This results in many different types of organic molecules.
So, from my understanding, carbon is the main key player for organic chemistry, the essence of biochemistry, and oxygen, nitrogen, iron and zinc are his sidekicks to make variety of structure with different purposes:
Iron -> heme group in hemoglobin
Oxygen -> for oxidation and energy
Nitrogen -> for protein
Phosphorus -> for back bone of DNA
You may ask why silicon cannot be organic even though silicon also has 4 valence electron to form 4 bonds, it is because silicon is a metalloid and cannot bond with other atoms. Its bond with itself and other atoms is not stable and stronger compare with Carbon atom.
Hope it helps! Stay Curious.
You *do* have iron! Just very little of it. An average human has about 3 or 4 grams of iron, or about 0.005% of the body. It's required for hemoglobin, which is in your blood.
Are you wearing that orange hoodie to look like phosphorus?
Sigh... Nice information mixed in with unnecessary abstraction. implying intentionally and "goal seeking" from atoms in the rhetoric is just lazy wrong.
Like, testosterone and estrogen don't "prepare your body for what's to happen". They do not have intentionality to know what "prepare" means. They are chemical compounds that interact with other compounds created by body systems due to a long chain of causality. We don't need to anthropomorphize functions of chemicals and physics. I find it often leads to accidental compartmentalization and hazing of spaces for inquisitive thought. Of course the benefit of simplified abstraction and thus subjective engagement with the scope of the symbolic makes for a more engaging and memorable video for recollection later...
I often hear "anthropomorphized" and "implied agency" with many videos, it's a thing I just ignore since it's a common way to communicate. It's much easier than saying "statistically likely"
