Crystals of Sodium Laurate, Lauric Acid (NaLLA) were obtained and the structure was determined by single-crystal X-ray diffraction. The new crystal form is monoclinic space group P21/c. asymmetric unit contains two independent laurate molecules whose carboxylic/carboxylate groups are linked a low barrier O-H…O hydrogen bond. Two lauric/laurate in head-to-head configuration elongated hydrophobic...

Abstract Fatty acids are important compounds for insects, but the requirements essential fatty may differ between insect species. Most of acquired through insect’s diet; therefore, supplementing diet with baker’s yeast (Saccharomyces cerevisiae Meyen ex E.C. Hansen), which produces unsaturated acids, was predicted to affect acid composition insect. The tested black soldier fly (BSF) (Hermetia i...

The caprylic, lauric, palmitic and stearic esters of solketal and glycerol formal were synthesized with high selectivity and in good yields by a solvent-free acid catalyzed procedure. No acetal hydrolysis was observed, notwithstanding the acidic reaction conditions.

We investigate the stability of seven inverse bicontinuous cubic phases [ G, D, P, C(P), S, I-WP, F-RD] in lipid-water mixtures based on a curvature model of membranes. Lipid monolayers are described by parallel surfaces to triply periodic minimal surfaces. The phase behavior is determined by the distribution of the Gaussian curvature on the minimal surface and the porosity of each structure. O...

The proportions of fatty acids in lipids of subcutaneous adipose tissue was compared in closely age-matched, urban men from two populations with a great difference in mortality from arteriosclerosis, namely in 50 Americans and 56 Japanese aged 15-65 yr who had died suddenly and unexpectedly. Specimens from both groups were analyzed side by side for fatty acids by gas-liquid chromatography. Comp...

This study was aimed at using the solid–liquid phase diagrams for three binary mixtures of saturated fatty acids, especially the phase transitions below the liquidus line. These mixtures are compounded by caprylic acid (C8:0) + myristic acid (C14:0), capric acid (C10:0) + palmitic acid (C16:0), lauric acid (C12:0) + stearic acid (C18:0), differing by six carbon atoms between carbon chains. The ...

Androgenetic alopecia (AGA), commonly referred to as male or female pattern hair loss, affects approximately 50% of the population by the age of 50. While AGA is primarily a cosmetic condition, it is associated with aging and reduced virility and hence has negative psychological and social impact on patients. A number of treatments have been proposed for AGA, many originating from botanical ext...

Cytochrome P450 4A11 (CYP4A11) is a fatty acid hydroxylase enzyme expressed in human liver. It catalyzes not only the hydroxylation of saturated and unsaturated fatty acids, but the conversion of arachidonic acid to 20-hydroxyeicosatetraenoic acid (20-HETE), a regulator of blood pressure. In this study, we performed a directed evolution analysis of CYP4A11 using the luminogenic assay system. A ...

Inspired by selective wettability and hierarchical structure of papillae on lotus seeds, papilla-like magnetic particles were fabricated by thermal treatment of Fe microparticles. The papilla-like magnetic particles modified by lauric acid exhibited superhydrophobicity, superoleophilicity and great oil removing capability from water.

An octapeptide, GAGAGAGY, was obtained by a novel method, i.e. hydrolysing Bombyx mori silk fibroin. Afterward, a dodecanoic acid-peptide conjugation was synthesized. This amphiphile assembled into cylindrical nanofibers of planar β-sheets at pH 9 and twisted β-sheets at pH 4.
