Studies were made on protein, carbohydrate and lipid from 28 marine algae from Lakshadweep Islands. The protein content ranged from 0.1 to 18.9% in green algae, 4.6 to 12.2% brown algae and 2.7 to 13.1% in red algae. The carbohydrate content was from 0.5 to 15.846, 1.5 to 13.0% and 2.0 to 29.4% in gMn, brown and red algae respectively. The lipid content varied from 2.6 to 13.8% in green algae, 2.2 to 8.3% in brown algae and 3.1 to 8.3% in red algae
