Chemical constituents such as heavy metals, lipids, phenol, vitamins, carrageenan, carbohydrates, antioxidants were estimated from Kappaphycus sp. From the studies, it was observed that the carbohydrate available in Kappaphycus sp. is 2.67 gm/100gm. Antioxidant potential of the red algae (Kappaphycus alvarezi) was determined by estimation of vitamin C, vitamin E, selenium and magnesium. The compositions of vitamin C, vitamin E, selenium and magnesium were found to be 0.123gm, 0.243gm, 0.0012gm, 0.0245gm per 100 gm respectively. It was noted that Kappaphycus is exhibited more antioxidant against vitamin E and magnesium. It was observed that total amount of the heavy metals is 30.4ppm. Iodine is the major constituent (56.77ppm) then boron (6.66ppm) and lead (3.45ppm) and nickel (2.43ppm). The composition of cobalt is 1.56ppm, mercury is 1.44ppm and cadmium is 1.02ppm. Very less amount of metals are arsenic (0.897ppm) and tin (0.89 ppm). The total lipid content was observed to be 1.09gms/100gms. The total protein content is as high as 18.78gm/100gm compared to all other substances. From study of vitamins, it was observed that the quantity of vitamin A is 1355.6 IU. Folic acid content is 1.22µg and choline is 0.676µg. Vitamins B1, B2, B3 and B6 are present in lesser quantity. B5 and B12 were observed to be in traces. Fat content in the species are found to be 1.09gm/100gm. Total phenol content is observed to be 4.565gm/100mg. Further, it was observed that the phenolic content is very much less than proteins and it is more than carbohydrates, lipids and fats. Carrageenan content is estimated as 1.095gm/100gm in the species. From the overall study, it can be concluded that the species can serve as functional food with vital nutritional and biological values.
