L-form (Laevorotatory form) is referred to the left handed configuration of amino acids[1] and it is the stereoisomer which makes plane polarised light rotates to the left[2]. Almost all amino acids form two type of enantiomers except glycine because it has two hydrogen atoms attached to the central carbon atom[3]. The two different stereoisomers are the D-form and the L-form[4]. The latter is the common form of amino acids and manufactured in the cells and L-amino acids are translated into proteins[5]. D-amino acids can be found in bacterial cell walls, but not in the cell[6] because it causes death[7]. It is said that the L-form and D-form are referred to life and death (L=living, D=dead)[8]
