Apolipoprotein (apo) C-I is a 57-residue exchangeable plasma protein distributed mainly in high and very low density lipoprotein. In this report we present the nuclear magnetic resonance spectra of native apoC-I and synthetic apoC-I, containing selected 15N-labelled amino acids, in the presence of sodium dodecyl sulfate. The proton resonances of apoC-I are assigned and the secondary structure is estimated from the difference of measured alpha-proton chemical shifts to random coil values and the observed NOE interactions. According to these data apoC-I forms two helices, Val-4-Lys-30 and Leu-34-Lys-52, linked by an unstructured region Gln-31-Glu-33. The N-terminal segments of each helix, Val-4-Gly-15 and Leu-34-Met-38, appear to be more flexible than the helical core regions Asn-16-Lys-30 and Arg-39-Lys-52.Key words: 15N-filtered NOESY, chemical shift index, amphipathic helix, lecithin:cholesterol acyltransferase.

The solubility of chlorophenols as affected by surfactant was investigated. Three kinds of surfactant, sodium dodecyl sulfate, Triton X-100, and Brij 35, were utilized. The solubilization of chlorophenols by surfactant follows the order of 2,4,6-trichlorophenol > 2,4-dichlorophenol > 2,6-dichlorophenol > 2-chlorophenol; and the critical micelle concentration is an important index. The adsorption reactions of 2,4-dichlorophenol and 2,4,6- trichlorophenol onto hydrous montmorillonite in the presence of surfactant were examined. The presence of surfactant decreased the adsorption of chlorophenols significantly. The roles of hydrophobicity of chlorophenols in solubilization and adsorption behaviors are discussed.
