In addition, there are lipid species in which sn-1 is ether-linked either to an aliphatic alcohol, termed an alkyl, or to an αβ-unsaturated alcohol, alk-1-enyl, which are referred to as plasmalogens (Fig. 5-2). While diacylglycerophospholipids contain an alkali-labile, acid-stable ...

which is produced from glycerol or from the intermediates in its synthesis, is the raw material for the production of epoxy resins. Glycerol is an important component of many food, cosmetic, and pharmaceutical products. It is used in the printing, leather, textile, and paper industries. Aqueous...
The process in question involves the reaction of vegetable oils with an alcohol (ethanol or methanol) in the presence of a catalyst to produce the diesel (with glycerol as the by-product). 有关过程涉及植物油与酒精(乙醇或甲醇)在催化剂的作用下发生反应制造柴油(甘油为副产品)。 UN-2 ...
What is an example of glycerol? Glycerol is also called glycerine (or glycerin). Nevertheless, the term “glycerol” is often used to indicate the presence of the compound as an ingredient of a product whereas “glycerine” (or glycerin) often pertains to the product name. For instance, the...
Glycerol is weakly acidic, being able to react with alkaline hydroxide. For example, it reaction with copper hydroxide can produce bright blue cupric glycerinate (can be used to identify polyols). Glycerol can react with nitric acid to generate glyceryl trinitrate, also known as nitroglycerin, bei...
have high dehydrogenase specificity to D-sorbitol by pyrroloquinoline quinine dependent alcohol dehydrogenase (PQQ-ADH) and FAD dependent sorbitol dehydrogenase (FAD-SlDH). The co-substrate fermentation of glycerol and 1% sorbitol resulted in 89.1 g/L GA with no DHA production. An enzymatic conversion...

In the adopted reaction conditions (55 °C, 6 h hours), the ratio of lauric acid to glycerol of 1:1 produces 26.8% dilaurin as a side product. CALB lipase (Candida antarctica) is a type of lipase immobilized on polysiloxane-polyvinyl alcohol particles (POS-PVA). This enzyme successfully ...
(L-type) shows sigmoidal kinetics with phosphoenolpyruvate. Fructose-1,6-bisphosphate is a positive modulator and decreases Kmfor phosphoenolpyruvate; ATP and alanine are negative modulators and increase Kmfor phosphoenolpyruvate. The former is an example of positive feed-forward regulation, and the ...
