A series of ι-carrageenans containing different amounts of v-carrageenan (0-23 monomer %) have been prepared from neutrally extracted carrageenan of Eucheuma denticulatum. v-Carrageenan is the biochemical precursor of ι-carrageenan. The conformational order-disorder transition and rheological properties of these carrageenans were studied using...

The coil-to-helix transition and temperature dependence of the viscosity of commercial κ/ι-hybrid carrageenans produced by the red algae Sarcothalia crispata, Mazaella laminarioides, and Chondrus crispus were studied using rheometry and optical rotation. The structure of these κ/ι-hybrid carrageenans was determined by 1H and 13C NMR spectroscopy...

The sequence fibrinogen-Aα-(148-160) can mimic part of the fibrin-induced rate enhancement of the activation of plasminogen by tissue-type plasminogen activator. Previously we have reported that the lysine residue at position Aα-157 is crucial. During our further investigations on Aα-157 we found that lysine at position Aα-157 may be replaced by...
