Proximate composition and amino acid content of red seaweeds, Kappaphycus alvarezii, from Langkawi and Sabah in Malaysia were determined in order to evaluate their potential nutritionalvalue. The crude fibre content of seaweed from Sabah (at 8.95%) was found to be significantly higher than that of Langkawi (at 7.86%) (P<0.05). The two seaweeds from Langkawi and Sabah respectively contained lipids (1.06, 0.97% dry weight), ash (16.305, 17.18% fresh sample), proteins (6.24, 6.89% dry weight) and moisture (80.87, 81.86% fresh sample) (P>0.05). Total 17 amino acids were found in both seaweeds, aspartic acid, gulamic acid, leucine are the majorconstituent and followed by. This study showed that Kappaphycus alvarezii from both habitats contained different amount of some of the essential amino acid and proximate composition it can be used as ingredients to improving nutritive value in human diets.
