ИНВЕРТАЦИЯ

Описание

Produced by the controlled fermentation of a number of species of Saccharomyces traditionally used in the manufacture of food. White to tan amorphous powder. Soluble in water (the solution is usually light yellow) but practically insoluble in alcohol, chloroform or ether. The major active principle is invertase, IUB No. 3.2.1.26, CAS No. 9001-57-4.

Химические свойства

solid

Использование

Invertase from baker′s yeast (S. cerevisiae) has been used:

• in liquid media (YES) and is used to determine the invertase activity
• supplemented to the reaction mixture in the extraction and analysis of sugars and starch
• for sucrose hydrolysis

Определение

Enzyme produced by yeast and by the lining of the intestines. It is a white powder, soluble in water. It catalyzes the conversion of sucrose (ordinary sugar) to glucose and levulose (fructose) during fermentation of sugars.

Общее описание

Invertase from Candida utilis is secreted in the periplasm. The molecular weight of invertase from C. utilis is 300 kDa. It is a dimer of identical subunits. It is a N-glycosylated protein, rich in mannose oligosaccharide in its structure. The invertase encoding gene of C. utilis shares high homology with SUC2 gene of Saccharomyces cerevisiae.
