Hello.
00:01
In this question we have been given a peptide, alanil, glutamil, glycel, alan, leucine.
00:08
Okay.
00:08
So it contains five amino acids which are alanin, glutamic acid, glycine, alanin and leucine.
00:15
Okay, so these are the five amino acids which are joined by peptide bonds.
00:19
Okay, now there are one, two, three, four, four peptide bonds in total, right? so let's go to the statements.
00:26
So the first statement says that there is a disulfide bridge okay there is no disulfide bridge because to have disulfide bridge we need to have cysteine amino acid right so since there is no cysteine amino acid it does not have a disulfide bridge so a is wrong then b says two free amino groups see all the amino groups they are busy in bonding right forming the peptide bonds so it does not have any free amino group okay then next is five peptide bonds see there are total four peptide bonds so c is wrong...
