Synthesis and activity of a novel diether phosphonoglycerol in phospholipase-resistant synthetic lipid:peptide lung surfactants().
This paper reports the chemical synthesis and purification of a novel phospholipase-resistant C16:0, C16:1 diether phosphonoglycerol with structural analogy to ester-linked anionic phosphatidylglycerol (PG) in endogenous pulmonary surfactant. This diether phosphonoglycerol (PG 1) is studied for phospholipase A(2) (PLA(2)) resistance and for surface activity in synthetic exogenous surfactants co...
متن کاملDesign of Surfactant Protein B Peptide Mimics Based on the Saposin Fold for Synthetic Lung Surfactants.
Surfactant protein (SP)-B is a 79-residue polypeptide crucial for the biophysical and physiological function of endogenous lung surfactant. SP-B is a member of the Saposin or Saposin-like proteins (SAPLIP) family of proteins that share an overall three-dimensional folding pattern based on secondary structures and disulfide connectivity and exhibit a wide diversity of biological functions. Here ...
متن کاملToxicity of Synthetic Surfactants to the Marine Macroalga, Ulva lactuca
The toxicities of three synthetic surfactants to the marine macroalga, Ulva lactuca, have been examined by monitoring chlorophyll a fluorescence quenching. The anionic surfactant, sodium dodecyl sulphate (SDS), exerted no measurable toxicity over the concentration range 0–10 mg L, while presence of the non-ionic surfactant, Triton X-100 (TX), elicited a small reduction in photochemical efficien...
متن کاملBiodegradation of synthetic surfactants: linear alkylbenzenesulfonates (LAS) and related compounds
Strain DS-1 is a small (0.8 μm in length and 0.2 μm in diameter) heterotrophic member of the α-Proteobacteria able to ω-oxygenate the commercial surfactant linear alkylbenzenesulfonate (LAS) and shorten the sidechain by β-oxidation to yield sulfophenylcarboxylates. The morphotype is widespread in cultures able to utilise LAS, and a second organism with similar characteristics, strain AN-8, is n...
متن کاملeffect of oral presentation on development of l2 learners grammar
this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
