    Acids Amino acids
AI Thread Summary
The discussion centers around identifying non-chiral amino acids, specifically those found in organisms. Glycine is confirmed as a non-chiral amino acid, but the participants are uncertain about the existence of two additional non-chiral amino acids. There is speculation that the question may be misleading, as it does not specify "alpha" or "proteinogenic" amino acids. One participant suggests that the question might be a trick, while another mentions Asx, Xle, and Glx, though these do not relate to chirality. The consensus leans towards glycine being the only non-chiral proteinogenic amino acid.

hi,
I've got a problem,which 3 amino acids are non-chiral ? I know there are many of them but I suppose they're only asking about those which are in organisms... I know about glycine but what are the other two ? thanks

Google a list of proteinogenic aminoacids and check. It is not that hard.
 
yes I've checked the table and the only non-chiral amino acid I found is glycine... so I;m asking what could be the other two they meant ...
 
I'm fairly certain that glycine is the only non-chiral proteinogenic amino acid.
 
Maybe it's a despicable trick question as they didn't say alpha amino acid nor proteinogenic?
 
they didn't say literally that which 3 proteinogenic , but I suppose they meant that because the text before talks about the amino acids in organims ... I answered it with Asx Xle and Glx ... I know that it has pretty much nothing to do with chirality...

Thread 'Did they discover another descendant of homo erectus?'

The study provides critical new insights into the African Humid Period, a time between 14,500 and 5,000 years ago when the Sahara desert was a green savanna, rich in water bodies that facilitated human habitation and the spread of pastoralism. Later aridification turned this region into the world's largest desert. Due to the extreme aridity of the region today, DNA preservation is poor, making this pioneering ancient DNA study all the more significant. Genomic analyses reveal that the...
