Digestion By Enzymes | Organic Chemistry | Chemistry | FuseSchool
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.

[@NeonAera]

Fascinating.. I have always have been curious how it all works. Thank you as well.

[@sidiquerodney7060]

Thank you so much! I'm sure to pass my biology test today!!❤❤👍

[@fuseschool]

Hope you passed!

[@free2contemplate]

Excellent description of how enzymes work. Thank you.

[@aqibmohammad1172]

Pepsin is probably the anomaly as it doesn't follow the 'ase' rule. Really good video though.

[@frederikbosman3278]

Pepsin is a protease

[@AbdurRehman-rz1lk]

What a vid.Never seen so much explanation.thnxs for helping me passing

[@fuseschool]

Thank you! Glad it helped!

oh god

[@waffleduck2903]

help this man

[@eviewhite7231]

take it for a “walk”

[@VamshiNetha1805]

great

[@KoolSkuirrel]

Great Vid Guys Keep It Up :)

[@mrgrizzly9034]

I just wanna say Thanku a zillion times 😘

[@fuseschool]

You are most welcome! 🤗

[@BumberenzoTheFireEngine]

My review for the term exams

[@sachinl6718]

Great vid🤙

[@Vthescout]

Thanks very much for the video

[@fuseschool]

No worries!

[@yannickmuzik]

Great video

[@fuseschool]

Thanks!

[@mahmoudbaajour9652]

❤️great video ❤️

[@fuseschool]

Glad you liked it!!

[@lisastan9661]

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

[@4kelly446]

The video says something about that when water is added it breaks the link.

[@isaella4229]

very useful! Thank you very much!

[@fuseschool]

Glad to hear that!

[@rufushodgkinson9859]

Good

[@r_yuuw7221]

Is this video okay to watch for 8th graders or am I just behind on my studies..? T^T

[@fuseschool]

Yup! Good to watch!

[@cookiecutter5162]

What can you do if your body isn't producing these enzymes like it should?

[@titanszs]

take enzyme pills

[@AkashDarwinBowse]

What about the enzymes "Trypin" and "Pepsin"? They clearly don't end in 'ase'.

[@ruwi0408]

Ptyalin is in the mouth while Amylasin is in the small intestine and they both break down carbohydrates.. Now that's the difference

[@asimhanif1360]

@ Jecko Bein D diff z tht thy both r in diff regions of d bdy SMPL

[@ruwi0408]

Note: the roughage is also called villi

[@invisi.]

roughage isn't villi

[@faithmadi2991]

no it isn't. Villi are projections along the lining of the small intestine for maximal absorption

[@vbsrekka]

I will not fail now... 😊😊

[@fuseschool]

Excellent 🙌

[@vbsrekka]

I was on seneca and this came up and it really helped me. Thanks again for your help! 😍😍

[@fuseschool]

You're most welcome! 🤗

[@Hellsfavouritemain]

Nice Kirishima pfp dude!

[@alexstruijk154]

Now I won't Fail :)

[@dejanirasloft]

Is there a transcript?

[@fuseschool]

Hi there! Part of the transcript is in the description below the video. Alternatively, there are KZbin generated automatic English captions that you could follow.
