Glycine, or aminoethanoic acid is the only amino acid that is not optically active as it does not contain a chiral carbon.
C2H5NO2
Glycine is the only non-optically active naturally occurring amino acid, due to it having no asymmetric centers. You may want to also check on Proline.
proline is not an amino acid it is an imino acid
Despite of containing two stereocenters (chiral centers) meso-tartaric acid is not chiral, because it is not stereospecific in the center of the molecule as a whole.A meso compound is superposable on its mirror image, and it does not produce a "(+)" or "(-)" reading when analyzed with a polarimeter.For example, of the 3 possible isomers of tartaric acid (depicted in 'Related links'), there is one mesocompound (the 2R,3S and 2S,3R isomers are equivalent) and two other optically active stereo-isomeric forms:dextrotartaric acid (L-(R,R)-(+)-tartaric acid) andlevotartaric acid (D-(S,S)-(-)-tartaric acid).Only in the meso compound an internal plane of symmetry exists, bisecting the molecule which is not present in the non-meso compounds. That is, on rotating the meso compound by 180° on a plane perpendicular to the screen, the same stereochemistry is obtained.
A dispensable amino acid, also known as a nonessential amino acid, is an amino acid that the body can synthesize on its own and does not need to be obtained from the diet. There are 11 dispensable amino acids in humans.
No, cysteine is a polar amino acid.
Glycine is an example of an optically inactive amino acid because it does not have a chiral center and therefore does not exhibit optical activity.

Optical isomers are those which have one or more asymmetric carbon atoms their optical activity means a tendency to rotate the plane of plane polarized light but some of such molecules have an internal symmetry as meso form of Tartaric acid , this is the optical isomer of Tartaric acid but is optically inactive.

proline is not an amino acid it is an imino acid
Anthranilic acid is not an amino acid because it lacks an amino group (-NH2) within its molecular structure, which is a defining feature of amino acids. Despite its name containing "acid," anthranilic acid is actually a precursor to various amino acids but is not classified as an amino acid itself.
False. A peptide bond joins the carboxyl group of one amino acid to the amino group of another amino acid.
the amino acid in the batteries is NH3+
there is amino acid in your stomach.
Yes, glycine is an amino acid.
