The presence of numerous complex organic molecules (COMs; defined as those containing six or more atoms) around protostars shows that star formation is accompanied by an increase of molecular complexity. These COMs may be part of the material from which planetesimals and, ultimately, planets formed. Comets represent some of the oldest and most primitive material in the solar system, including i...

Article: A growing body of evidence links personal behaviors to many chronic diseases and increased mortality (1, 2). The 1979 U.S. surgeon general's report (3) identified the following behavioral changes as desirable to promote health in the American population: elimination of smoking; decreased consumption of alcohol, excess calories, saturated fat, cholesterol, salt, and sugar; increased exe...

The sugar alcohol meglumine enhances the solubility of organic compounds in water and enforces formation electron donor–acceptor (EDA) complexes, enabling photochemical C−C C−S cross-coupling transformations without sensitizers. light-driven redox-neutral protocol connects haloarenes with indoles, anilines, anisoles, thiols, as reported by Burkhard König co-workers their Research Article (e2022...

BACKGROUND Young adulthood is associated with poor dietary habits and vulnerability to weight gain. Population studies have revealed that inadequate fruit and vegetable intake, excessive sugar-sweetened beverages, and frequent takeaway food consumption are dietary habits requiring intervention. OBJECTIVE The aim was to examine the dietary patterns and diet quality of overweight young adults o...

BACKGROUND High sugar consumption contributes to the rising prevalence of obesity. Sugar can have rewarding effects that are similar to, but less strong than, the effects of addictive substances. People who consume large amounts of sugar also tend to use more addictive substances, but it is unclear whether this is due to shared genetic or environmental risk factors. OBJECTIVE We examined whet...

Sugarcane and agave bagasse samples were hydrolyzed with either mineral acids (HCl), commercial glucanases or a combined treatment consisting of alkaline delignification followed by enzymatic hydrolysis. Acid hydrolysis of sugar cane bagasse yielded a higher level of reducing sugars (37.21% for depithed bagasse and 35.37% for pith bagasse), when compared to metzal or metzontete (agave pinecone ...

Hygromycin A is interesting from the standpoint of the previously undescribed sugar it contains, 5-keto-6-deoxy-n-arabohexose (2,3). The pathway of biosynthesis of this compound is unknown. In this study, Streptomyces hygroscopicus was grown in the presence of specifically labeled glucose, and the distribution of radioactivity in the 5-keto-6-deoxy-n-arabohexose of hygromycin A was determined. ...

Xylitol is a five-carbon sugar alcohol, a natural carbohydrate which occurs freely in certain plant parts (for example, in fruits, and also in products made of them) and in the metabolism of humans (1). Xylitol has been known to organic chemistry at least from the 1890's. German and French researchers were obviously the first ones who made xylitol chemically more than 100 years ago. This reacti...

This paper looks at the theoretical development of a natural preservative system using a data base on medicinal plants as a source of reference. The legal aspects of this concept are considered. The traditional methods of preservation, many taken from the food industry are summarised. The use of alcohol, glycerine, sugar, salt, dessication, anhydrous systems and temperature are amongst examples...

Vegetable oils are frequently structured to enhance their organoleptic and mechanical properties. This is usually achieved by increasing the net amount of saturated and/or trans fatty acids in the oil. With the risk of coronary heart diseases associated with these fatty acids, the food industry is looking for better alternatives. In this context, the medium-chain dialkanoates of low-calorie sug...
