Of the laser Raman temperature poly-lysine different relative secondary structure elements
Component of the curl. This analysis and quantitative calculations. : The above study shows that polylysine molecules due to changes in its internal water content f from the secondary structure of the molecular internal rhyme was temporarily Health Science Report 1990 Fjg soil RamanSpectraofPoly-L-l ∞ a) atRH33% ba £ RH0 changes . When & H33% and 75% of the conformational transition that occurred two molecules to fold from the random coil shift into the second folded conformation changes to the spiral. Each measured with infrared residue of a water molecule to four water molecules for the structure, more than four water molecules to spiral, less than one water the same as for the random coil L]】. Although the interpretation of this phenomenon,[link widoczny dla zalogowanych], but there is no unified theory of the hydration of protein films to promote amide I,[link widoczny dla zalogowanych], Ⅲ changes show that carbonyl and amine effects by strong hydrogen bond, together with the increase of water molecules distal calf acid molecules gradually The new key stage so that the molecular structure of water molecules more closely. Poly-lysine molecules on the main peptide chain and a variety of side chain polar groups to form a variety of easily with water molecules H-bond energy distribution of which was weaker than or similar to water, such as a water hydrogen bonds oHNH, NH,[link widoczny dla zalogowanych], Co However,[link widoczny dla zalogowanych], some groups than as strong as the Coo a, NH +, CooH and so on. In addition to protein and water molecules easily form a variety of energy distribution of H and health,[link widoczny dla zalogowanych], should consider the interaction of van der Waals force. Not difficult to see from the above phenomenon of water increased the protein molecules so that the main chain of Middle coiled into a helical structure more closely; spatial structure of molecules into more water came from a loose random coil state. Other molecules in the spiral, folded and random coil components with which the number of water into the step-type halo discontinuous.
