Biochemistry of ABO Antigens

The ABO blood group system is used to denote the presence of one, both, or neither of the A and B antigens on erythrocytes.
Blood groups are inherited from both parents. The ABO blood type is controlled by a single gene (the ABO gene) with three types of alleles inferred from classical genetics: i, IA, and IB. The I designation stands for isoagglutinogen, another term for antigen. The gene encodes a glycosyltransferase—that is, an enzyme that modifies the carbohydrate content of the red blood cell antigens. The gene is located on the long arm of the ninth chromosome (9q34).

Very easy to understand! You explained this better than my lecturer ever did! 🤝🔥

[anonymed]

great simplification, just one thing : the FUT1 encoded by H gene is in the locus of the 19th pair of chromosome ( A and B alleles are in locus of 9th pair ) :)

Thank you sir, You have made a clear explaination of what others make so complicated. I like what you do and I think you should contine as you are clearly very talented.

[martinchan]

Very good teaching skills. Made easy to understand the general idea of ABO blood group systems. Thank you.

[faizmohammadshee]

Beautiful Explanation. Simple and straight forward.

[ashokpatil]

One mistake FUT 1 gene located on chromosome no. 19 not 9,
While explaining you said 19 but you written 9

Thanks ☺...may Allah(s.w.t) bless u and keep continue blessing u always with peace and happiness and all the sucess in ur life of this duniya and hereafter😊

[guptaghanshyam]

it is very easiest way of explanation of blood group thank you so much sir

[komaldhyani]

Why you are so amazing! Always to the point. Thank you so much 🙏

[ellios]

Thank u so much
I was exactly looking for this

[amayra]

Thanks a tonn.. U can't imagine how mch it helped me.. ❤

[lipsunibedita]

Thank you sir for much better explanation

[Ks-mokt]

Thanks a lot sir_ This topic had been irritating me. You made so simple and easy to understand_ ☺️

[Micro-life]

Sir nice to knw abt the O-antigen😊....thnx fo the clarificatn

[md]

Thnkq sir, for such a simple n understandable video .. it really hlpd a lot 😄

[Jaikrishna-bcgi]

Ur teaching method is so amazing 😍 thanks alot

[doctordr]

Superb sir very awesome way of teaching love it 👍👍👍

[kavyamorya]

Thank u for explanation of biochemistry of ABO antigen nd also for that H antigen.my blood grp is o -ve nd for these many yrs I was under impression that o blood type don't hv antigen.thanks again.

[henrydillon]

Thanks for the explanation i'm confused a little bit. The last video I watched started started the O-oligosaccharide sequence with galactose and ended with fucose but yours starts with glucose before galactose. How's that?
