In this video we examine the process of digesting our food. We shall see how biological catalysts called enzymes break these food molecules apart and why they are necessary.
Think of our food molecules as a train of trucks all coupled together. Digestion disconnects the trucks so we can re-assemble them in our own way.
The breaking takes place by hydrolysis - a reaction where water is added and breaks the link. Let’s look at the simplified reaction for each of the foods we eat:
Starch is a polymer of simple sugars which are joined by a glycosidic link C-O-C . When water is added the link breaks.
Proteins are polymers of amino acids are joined in by the amide C-O-N-C link. Water breaks the chain into separate amino acids.
The nucleotides in the DNA double helix are joined by phosphate groups. Water breaks the link.
In the same way fats are hydrolysed into glycerol and fatty acid, such as stearic acid used in soap making! Water breaks the link
Once our food is digested into monomers the molecules are small enough to get though the walls of our gut and into our blood ready to be used as fuel (sugars, fats and oils ) or to build up our own proteins and DNA.

Fascinating.. I have always have been curious how it all works. Thank you as well.
Excellent description of how enzymes work. Thank you.
Thank you so much! I'm sure to pass my biology test today!!❤❤👍
Hope you passed!
What a vid.Never seen so much explanation.thnxs for helping me passing
Thank you! Glad it helped!
Pepsin is probably the anomaly as it doesn't follow the 'ase' rule. Really good video though.
Pepsin is a protease

great
Thank you for a great video!
Glad you liked it!
excellent description. thank you
Very good!
🤙🏻
Help my goldfish is trying to kill me
oh god
help this man
take it for a “walk”
Nice video :P
Thanks 😅
Great Vid Guys Keep It Up :)
Great vid🤙
Thanks very much for the video
No worries!
Great video
Thanks!
I just wanna say Thanku a zillion times 😘
You are most welcome! 🤗
My review for the term exams
❤️great video ❤️
Glad you liked it!!
very useful! Thank you very much!
Glad to hear that!
Good
Still dont get it chemical reaction are used to combine two substance to produce new substance but how chemical reaction occur in digestion when they are used to breakdown foods? Answer me pls
The video says something about that when water is added it breaks the link.
Is this video okay to watch for 8th graders or am I just behind on my studies..? T^T
Yup! Good to watch!
What can you do if your body isn't producing these enzymes like it should?
take enzyme pills
What about the enzymes "Trypin" and "Pepsin"? They clearly don't end in 'ase'.
Ptyalin is in the mouth while Amylasin is in the small intestine and they both break down carbohydrates.. Now that's the difference

I will not fail now... 😊😊
Excellent 🙌
I was on seneca and this came up and it really helped me. Thanks again for your help! 😍😍
You're most welcome! 🤗
Nice Kirishima pfp dude!
Now I won't Fail :)
Is there a transcript?
Hi there! Part of the transcript is in the description below the video. Alternatively, there are RUclips generated automatic English captions that you could follow.
Note: the roughage is also called villi
roughage isn't villi
no it isn't. Villi are projections along the lining of the small intestine for maximal absorption
OOOOH MONIKA
how tf is this supposed to help me
