Abstract
RECENTLY we have been successful in synthesising amino acids by exposing solutions of glycol or glucose and nitrates to sunlight for six to eight hours in presence of titania, used as a photocatalyst. The amino acids formed can be estimated colorimetrically by the valuable ninhydrin (triketo-hydrindene hydrate: test. The following results were obtained by exposing to sunlight 100 c.c. of N/2 nitrate solutions and 5 gm. of glucose and 1 gm. of TiO2 in open 250 c.c. pyrex glass beakers:
