Hello, my dear students, the concept given is about the enzyme glycosyl transferase, which i'll be mentioning it as gt in the explanation.
00:18
And what is required for us is to know its action or its substrate in the metabolism it is catalyzing.
00:31
Okay? so let us get into the explanation.
00:34
Now this enzyme glycosyl transfer is the one which catalyzes to transfer glucose sugar residue from one sugar molecule to the other acceptor or a moiety.
01:07
And most probably from one sugar molecule or from one substrate.
01:16
It transfers the sugar residue from one of it to the other, okay? which is the right acceptor for the sugar residue.
01:26
That is what it catalyzes.
01:29
Now given in the option, the first one says gdp manos, which is elaborated as guanin, diphosphate, phosphate as well as manus.
01:47
So this is actually a nucleotide sugar, which is a substrate for glycosyl transferase metabolism or reaction.
02:05
Okay, the first one is the substrate, one of the substrate.
02:09
The next one is udp, gal, n, a, c.
02:15
C.
02:16
Okay.
02:17
So this one is uridin, diphosphate, n -acetyl, galactose amine.
02:31
Okay.
02:35
It's a bigger expansion.
02:38
So this is also a nucleotide sugar and it has also been catalyzed as a substrate in or by the activity of glycosal transferase reaction or the enzymatic function.
02:52
Okay.
02:53
Yes.
02:54
Now the third one is what we need to discuss.
03:00
The third one is nothing but gal, nac, gallactose, okay? which is an amino sugar...
