1. Monoglyceride biosynthesis from coconut milk with lypase enzyme of sesame seed sprouts as biocatalyst
Abstract Monoglycerides are oleochemical compounds that were widely used as emulsifying agents for foods, anti-bacterial and anti-viruses (monolaurin, monocaprin). The objective of this research was to study the optimal reaction conditions in monoglyceride production from coconut milk. To achieve that purpose, the research was carried out with two factors, n

2. Polyurethanes Obtained by Reacting 1,6-HDI with Monoglycerides from Babassu Oil: A DFT Study
This is a density functional theory (DFT)-based (M06) study on the polyurethane formation from 1,6-hexamethylenediisocyanate (1,6-HDI) reacting with the monoacylglycerol obtained from the babassu oil. As the lauric acid is the most abundant fatty acid in the vegetable oil, the 2-monolaurin was chosen to scrutinize the polyurethane formation. An analysis of t

3. Synthesis, characterization and antibacterial activity of novel poly(silyl ether)s based on palm and soy oils
Abstract In this research, palm oil and soy oil were used as a natural polyol to prepare novel poly(silyl ether)s. Palm oil and soy oil were first converted to monoglyceride by one step via alcoholysis process in the presence of 0.1% CaO as a catalyst. The monoglycerides were characterized by Fourier transform infrared spectrometer (FT-IR), nuclear magnetic

4. Metabolite profiling of Schizochytrium sp. by GC-MS, an oleaginous microbial source of biodiesel
The chemical screening carried out on Schizochytrium sp. biomass led the identification of 24 types of organic compounds belonging to n-alkanes, 1-alkenes, 1-alkanols, free fatty acids, methyl and ethyl esters of saturated and unsaturated fatty acids, saturated tri- and diglycerides, unsaturated monoglycerides, wax esters, sterols, triterpenes, and mono- and

5. Caracterização de resíduo sólido formado em biodiesel de sebo bovino
The nature of the solid residue formed in beef tallow biodiesel from two commercial producers in Brazil was determined by comparative analytical techniques, namely, gas chromatography with flame ionization detector (GC-FID) and thermogravimetry (TG). Pure monopalmitin and monostearin were used as reference standards for both methodologies. Analyses were carr

6. Obtenção de concentrados de monoacilgliceróis a partir do óleo de girassol / Monoacylglycerols concentrates obtained from sunflower oil
Monoacilgliceróis (MAG) são emulsificantes utilizados em produtos alimentícios, farmacêuticos e cosméticos. A obtenção de MAG a partir de óleos vegetais vem se destacando frente aos processos industriais devido aos benefícios que compostos naturais trazem à saúde humana. Industrialmente, são produzidos através da glicerólise química de triacil

7. Enzymatic route selection for monoglyceride production using immobilized lipase on matrix obtained by sol-gel technique / Estratégias para desenvolvimento de um sistema operacional eficiente para a produção enzimática de monoglicerídeos
The objective of this project was to select the best enzymatic route to produce monoglycerides using lipase immobilized on matrix obtained by sol-gel technique, aiming to contribute for a better utilization of the glycerol generated as by-product in the biodiesel synthesis. For this purpose two methodologies were analyzed: (1) direct esterification of the gl

8. Monoglicerídeos: produção por via enzimática e algumas aplicações
Monoglycerides (MAG) are non-ionic surfactants, widely used in the pharmaceutical, food and cosmetic industries. Although MAGs are manufactured on an industrial scale by chemical glycerolysis of oils and fats, new developments in lipase catalyzed synthesis have been studied as an alternative to the classical method seeking to use clean technology and green c

10. Obtenção de monoglicerideos de alta concentração atraves do processo de destilação molecular / Production of high concentration monoglycerides using molecular distillation process
Monoglicerídeos são emulsificantes amplamente utilizados em alimentos, fármacos e cosméticos. Industrialmente, são produzidos através da interesterificação de triglicerídeos com glicerol, a altas temperaturas (>200°C), na presença de catalisadores inorgânicos. Também conhecida como glicerólise, esta reação produz uma mistura com aproximadamen

11. Extreme Sensitivity of Enveloped Viruses, Including Herpes Simplex, to Long-Chain Unsaturated Monoglycerides and Alcohols
Unsaturated monoglycerides and alcohols of chain lengths of 16 or 18 carbons were found to be extremely potent inactivators of two enveloped viruses, herpes simplex virus type 2 and bacteriophage φ6. The lipid-containing bacteriophage PM2 was also inactivated by some of these amphiphilic molecules. Treatment of herpes simplex virus type 2 with these compoun

12. In Vitro Susceptibilities of Neisseria gonorrhoeae to Fatty Acids and Monoglycerides
The susceptibility of Neisseria gonorrhoeae to several medium-chain fatty acids and their 1-monoglycerides was tested at a short inactivation time of 1 min. The results indicate that monocaprin, a monoglyceride of capric acid (10 carbon atoms, no double bonds), causes the fastest and most effective killing of all strains of N. gonorrhoeae tested.
