Hello aspirant
SomeD-amino acidsarefoundin the cell walls of bacteria, but not in bacterial proteins. Glycine, the simplestamino acid, has noenantiomersbecause it has two hydrogen atoms attached to the central carbon atom. Only when all four attachments are different canenantiomersoccur.
They are not found in Protein because the t-RNA used to activate theamino acidsduringproteinsynthesis donotrecognizeD amino acids. On the other hand,D-amino acidshave been detected in a variety of peptides synthesized in animal cells. ... TheseD-amino acidsform when L-amino acidsundergo post-translational enzymatic modification.

Hello atul,
D-Amino acids are amino acids where the stereogenic carbon alpha to the amino group has the D-configuration.
For most naturally-occurring amino acids, this carbon has the L-configuration.
D-Amino acids are most occasionally found in nature as residues in proteins. They are formed from ribosomally-derived D-amino acid residues.
Diverse D-amino acids, such as D-serine, D-aspartate, D-alanine, and D-cysteine, are found in mammals. Physiological roles of these D-amino acids not only in the nervous system but also in the endocrine system are being gradually revealed.
HOPE THIS WILL HELP YOU
GOOD LUCK!
