Alpha Amino Acids – Biomolecules – Chemistry Class 12



click the bell icon to get latest videos from akira reference in the bridge topic we have discussed about the puddings and that we have worked on all that is foodies are made up of elf amino acids so in that case we are going to talk about the Alpha amino acid and for that we have to discuss about it so now let us discuss about it in this topic so Fink's in this topic I am going to talk about the Alpha amino acids so what are l5 no assets that is alpha acids are the derivatives of the carboxylic acids obtained by replacing the Alpha hydrogen atom by the amino group so for example me and I said that is suppose if I take a common example that is for acetic acid that is CH 3 C double bond o o H so this is a function group that is the carboxylic acid group and which is attached to this carbon atom so this carbon atom is considered to be the alpha carbon atom and all the hydrogen's are PC known as the Alpha hydrogen atoms and suppose in this case suppose if we have replaced to the Alpha hydrogen atom with a particular amino group than that carboxylic acid derivative it will be called as alpha amino acid so for that let me give you the general representation for the Alpha amino acid and that is C H this one would be R here it would be C Oh Oh H and this is nothing but an edge 2 so in this case this is basically the alkyl group or this would be any group which would be associated with this carbon atom and this is basically the general representation for the l5 acid and why the name is alpha amine acid because as you can understand because the amino group is attached to the Alpha carbon atom that citizen alpha amino and this is itself a carboxylic acid derivative and the reason the name is alpha amino acid so talking about this group so this could be al-qaeda group or it could be any cyclic group so based on that let me give you a certain example related to the Alpha amino acid so then this is the data where we could get the different types of the Alpha amino acids so there are different types Elfangor sense and in that case basically is suppose if the our group is replaced by a certain and suppose if our group is replaced by this groups so what the elf I'm know as it would be corn and what are their three letter symbol so this is what I'm going to talk about so suddenly the first one that is suppose if we have replaced the R with hydrogen atom so in that case the alpha amino acid rate would be called as glycine for example if we have replaced the Al group with ch3 so that for it will be called as Ln I'm and talking about this one so this is nothing but this is what we have is an ISO do time and suppose if we have replaced with an isopropyl so therefore the name of that would be aligned so this case the Valen is nothing but it is an essential amino acid but let me talk about what is essential and what is non-essential in my next topic but this are certain things that is I am going to talk about the Alpha amino acids so talking about the other one that is privacy in say right so this all are the groups that could replace the R group of the general representation for the Alpha amino acid and this is what I want to talk about so talking about these three letter symbols so every alpha when I said it has a particular name depending upon the R group associated with it so that is for example if we talk about glycine so glycine is represented by GL Y suppose if I talk about the phenyl alanine so in that case it is represented by pH II suppose if we talk about tryptophan so in that case we represent it with three letter word that is TRP so in that case basically this let us suppose they play a very vital role in that is in designing a DNA or in studying a particular DNA so this is what I want to talk about related to the FML acid and that's it so thank you for watching this video I hope you have understood this very very clearly and I hope I'll see you next time till then don't forget to subscribe aggression of thank you so much you
