Abstract

Spiders are unique in their ability to synthesize and utilize silk for various purposes. The primary structure of silk is its amino acid sequence, mainly consisting of highly repetitive blocks, which is why silks are often referred to as a block co-polymer. This attempt was made to characterize silk of Lycosiedae and Eresidae for the functional groups amino acids by FTIR spectroscopy. The test results shows that, the silk of Lycosideae contain strong –COOH asymmetrical vibration and –NH3 symmetrical bending vibration for Glumatic acid and Lysine, while in Eresidae,  Argnine amino acid and with -NH2 medium bending vibrations. Both the silk samples show presence of Beta – sheet secondary protein structure. In Lycocedae, strong vibrations in Amide-I region, while in Eresidae, medium vibrations get observed. Amide-II band are absent in Eresidae. Amide –B band are observed in both the samples.
