Most AMPs discovered in invertebrates were found in arthropods including insect, and antibacterial activity was discovered by specifically high frequency against Gram positive bacteria. The length of peptides discovered the highest amount in 31~40 peptides, and it maintained comparatively higher levels in 11~50 peptides. The secondary structure of peptides showed the highest value in alpha-helix, but very lower amounts in beta-sheet and coil form. As net charge was ranged from +1 to +7, it was observed to have a net charge slightly higher than general AMPs. Aliphatic index was observed to have the largest amount between 70 and 80, which more than half of the peptides were found to form a stable structure. Therefore, it is suggested that AMPs found in invertebrates have characteristics similar to AMPs discovered in all the organisms.
