摘要:摘要 利用微生物来源的非特异性和 1,3-特异性脂肪酶,在低水分介质中对棕榈油进行了酶法酯交换反应.首先将酶固定在 Celite 上,冻干 4 小时,然后加入到由 10% (重量/体积)棕榈油和水饱和正己烷组成的反应介质中.通过反相高效液相色谱法(HPLC)测定甘油三酯(tg)成分和浓度的变化,以及滴定法测定游离脂肪酸的形成,评估了酶的催化性能.使用皱褶念珠菌脂肪酶进行的研究表明,干燥固定化制剂可降低水解程度,最佳干燥时间为 4 小时.在所有情况下,酯交换过程都会形成 Ppp(一种最初在油中未检测到的 Tg),Ooo(1.3-2.1 倍),Ool(1.7-4.5 倍)和 Oll(1.7-4.3 倍)的浓度也会增加,其中 P,O 和 L 分别指棕榈酸,油酸和亚油酸.油中未检测到的另一种 Tg--Sos(其中 S 是硬脂酸)由米黑根瘤菌和假单胞菌脂肪酶合成,后者产生的这种 Tg 更多.pop,Plp,Poo 和 Pol 的浓度也相应降低.假单胞菌脂肪酶引起的变化程度最大,速度最快,其次是米氏粘杆菌和黑曲霉的酶.各种脂肪酶对棕榈油油脂的酯交换作用和水解作用导致甘油三酯成分的总体饱和度发生变化.酶的位置特异性与形成的产物之间似乎没有明显的相关性.本文讨论了形成 Ppp,Ool,Oll,Ooo 和 Sos 的可能机制.

标题 :Continuous process for the synthesis of sucrose fatty acid esters
发明人：WILSON DONALD C
权利人:OPTIMA TECHNOLOGIES GROUP
摘要:This present invention pertains to a process for the synthesis of sucrose fatty acid esters by reacting sucrose and a purified specific fatty acid ester under substantially solvent free conditions in the presence of a transesterification stationary catalyst and mechanical emulsification. The process is continuous, yielding selected individual products of separated simple sucrose fatty acid esters of mono-, di-, tri- and polyesters while recycling the unwanted ester fractions, the unreacted sucrose and fatty acid ester.

标题 :Methods and compositions for enhancing collagen and proteoglycan synthesis in the skin
发明人：NIMNI MARCEL; HAN BO
权利人:NIMNI MARCEL; HAN BO
摘要:A composition for application to the skin can stimulate the in vivo synthesis of collagen and proteoglycans and improve the appearance of the skin, increasing its elasticity and fullness. In general, a composition according to the present invention comprises: (1) an antioxidant compound in a quantity sufficient to enhance collagen synthesis in the skin; (2) an organic penetrant in which the antioxidant compound is soluble in a sufficient quantity that a concentration of the antioxidant compound sufficient to enhance collagen synthesis can be applied topically and penetrate the skin; (3) a mixture of essential amino acids; (4) a supplemental source of sulfur; and (5) a topical pharmaceutically acceptable carrier. The antioxidant compound can be lipoic acid, a lipoic acid analogue or derivative, a bioflavonoid, a constituent of ginkgo, or an isoflavone. The organic penetrant is preferably benzyl alcohol. Other ingredients, such as esters of tocopherol and ascorbic acid, can be included.

摘要:Disclosed is a diacylglycerol acyltransferase 1, a recombinant Saccharomyces cerevisiae containing the diacylglycerol acyltransferase 1, and application thereof in production of triacylglycerol. The diacylglycerol acyltransferase 1 of the invention has a function of catalyzing synthesis of triacylglycerol. After the recombinant Saccharomyces cerevisiae containing the diacylglycerol acyltransferase 1 of the invention is subjected to induction culture for 48 h, the content of total fatty acid and triacylglycerol in the recombinant Saccharomyces cerevisiae containing the diacylglycerol acyltransferase 1 can be respectively increased by 1.94 folds and 12.09 folds as compared with those of Saccharomyces cerevisiae without the recombinant diacylglycerol acyltransferase 1. The instant invention provides a method for improving the ability of microorganisms to produce polyunsaturated fatty acids (PUFAs) by means of genetic engineering.

标 题:Synthesis of new methylumbelliferone prodrugs and their incorporation into lipid-based drug delivery formulations
发明人：SZOKA FRANCIS C JR; DAI ZHIPENG
权利人:ZONEONE PHARMA INC
摘要:Lipophilic prodrugs of 4-methylumbelliferone are incorporated into lipid based drug delivery systems (e.g., emulsions, micelles, liposomes and lipid particles). The formulations protect 4-methylumbelliferone from first pass hepatic metabolism to 4-MUG. Exemplary formulations are oral and parenteral formulations. Methods of treating proliferative diseases, e.g., cancer by administering the formulation to a subject in need thereof are provided.
