how to find charge on peptide at different pH - BIOCHEMISTRY PROBLEM CSIR-NET JRF LIFESCIENCE

[@ayushimandal701]

Thank you so much...I was searching for the trick to solve this type of questions but there were no such videos available then suddenly I saw your channel & you won't believe how much beneficial is this video. The way you teach is awesome. Thank you again. Now I'm able to solve all questions related to this topic

[@AliyaZainab-o4p]

you just saved my whole semester😍😊

[@shadow_of_4th_dimension]

Ma'am here you have mentioned about the pKa of the groups??? The charge of the ionizable groups depends on on whether the pH is than pKa isn't it???

[@rishuyadav2871]

Mam it's very helpful for all thankyou for this amazing video. ❤

[@preety1810]

3.5 pr Coo- nahi hoga kya??? C end mein???

[@LUFFYx69x]

❤❤ thank u so much mam

[@spatil4878]

Mam, how to solve this if pH is 7

[@BioMonkMaster]

Very Nice explanation. Best wishes

[@mrigakshisonowal1842]

Thank you so much for making it so easy

[@rinkup9069]

Thank you di, for this demanding video 😘

[@mahnoorfatima.4]

Thanks to you❤

[@aarjvijain]

Trick is good, however, it will not work in all cases. You need to consider Pk(R) values for sure

[@abinashsamal6558]

How to solve the question
E-H-R-G PH at 3,7,11
It's not working as of your method

[@DineshDara-uy3vr]

Thank you

[@ruksarkhan1277]

Mam what about methionine... Wo bhi to sulphur containing a.a h... Higher pH pe wo bhi H+ de dega kya cysteine ki trh

[@ruksarkhan1277]

Plz reply mam

[@alecgarg6354]

Tysm mam 🙂🙂 u made it simple and easy

[@Anchal026]

Mam wht about ph 7 pleasee tell ???

[@futureteacher7550]

Thank you mam❤

[@Shivangi-ek3dp]

Mam ser aur tyrosin me bhi to OH group hota h

[@prachishekhawat1094]

Thank you mam you made it so easy

[@gt4291]

Very nice video .God bles you

[@rajghosh4485]

Classical explanation 💥🤗

[@vishalrana7837]

Thank you ❤

[@ankitasharma4041]

Thank you ma'am ❤

[@Chirag-ml2mg]

Thank you so much ma'am

[@gauravyadav.100]

Good lecture

[@rajnandinibag6601]

Thanks a lot Didi ❤️

[@gagandeepsingh6032]

Best explanation ❤❤

[@kajolkumari5621]

Thank you so much 💞

[@Smiley43016]

Please tell me pH = 7 wala kaise hoga....

[@daisykumari2912]

What is the net charge of pentapeptide Lys-Gly-His-Ala His at physiological pH is

[@NidhiSharma-nk3ks]

+1 charge
Terminal charge neglect

[@anjanavij626]

Thank you Mam...

[@Nisha-uz4nv]

Serine has also OH group like tyrosine

[@bhumikaadhikari1192]

I'm also confused about that

[@anukulpaul617]

Please tell me if there is a tyrosin residue in the midle of the peptide and ph is 12 then what will be the charge on tyrosine residue?

[@NidhiSharma-nk3ks]

Coo ion

[@Pearl235]

-1

[@Salamatkiamanat]

Methionine me bhi sh group hota hai side chain me
Tryptophan

[@-stanlee-1046]

Sh nahi s hota ha

[@biotechnerdvasu]

Mam add more numerical videos for csir

[@aswalaswal6321]

Thku

[@Muzee123]

What of r chain is different 😔😀

[@tanyagupta9206]

7 pe kese krenge

[@poorvijain1102]

At ph 7, you didn't tell?

[@Smiley43016]

Yes kaise pH ..7 wala kaise hoga

[@mohsinkhan895]

Dislikeres don't want to qualify CSIR NET JRF

[@Muzee123]

Concept not cleared doubts ha

[@Dyson2024]

Any jee aspirant😂

[@mahnoorfatima.4]

Teachers ho tou asy ho warna ho he na 🫠

[@achiever7868]

Ye galat method he 😝

[@achiever7868]

At 3.5,Alpha COOH is deprotonated

[@mahnoorfatima.4]

@@achiever7868 jb environmemt acidic zyada hota hy akal mand admi tou protonation hoti hy, specie proton leiti hy.. na ky deiti hy.
Jb ni samajh aye ja kr concepts clear kro

[@achiever7868]

​@mahnoorfatima.4
Take it easy
To calculate this kind of questions,we have to consider pk1,pk2,pkR value
The pk1 value of Alpha COOH of Cysteine is 1.96 which is lower than pH 3.5
So it will be deprotonated
For further information
Watch "Vedemy Charge and pI calculation"

Mam what about at ph 7
