Many adult humans lack the lactase enzyme, which has the same function as β-galactosidase, so they are not able to properly digest dairy products. β-Galactose is used in such dairy products as yogurt, sour cream, and some cheeses which are treated with the enzyme to break down any lactose before human consumption. In recent years, β ...
This observation was first published by Otto Heinrich Warburg, [2] who was awarded the 1931 Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme". [3] The existence of the Warburg effect has fuelled popular misconceptions that cancer can be treated by dietary reductions in sugar and ...
First, glucose metabolism is faster through ethanol fermentation because it involves fewer enzymes and limits all reactions to the cytoplasm. Second, ethanol has bactericidal activity by causing damage to the cell membrane and protein denaturing, allowing yeast fungus to outcompete environmental bacteria for resources. [6]
Lactase (EC 3.2.1.108) is an enzyme produced by many organisms and is essential to the complete digestion of whole milk. It breaks down the sugar lactose into its component parts, galactose and glucose. Lactase is found in the brush border of the small intestine of humans and other mammals.
Medical research for cancer begins much like research for any disease. In organized studies of new treatments for cancer, the pre-clinical development of drugs, devices, and techniques begins in laboratories, either with isolated cells or in small animals, most commonly rats or mice. In other cases, the proposed treatment for cancer is already ...
Yeast Metabolome Database; Content; Description: Metabolomics database: Data types captured: Yeast metabolite structures, metabolite descriptions, metabolite reactions, metabolite enzymes and transporters, yeast enzyme and transporter sequences, chemical properties, nomenclature, synonyms, chemical taxonomy, metabolite NMR spectra, metabolite GC-MS spectra, metabolite LC-MS spectra
[47] [48] This study shows that L. lactis NZ9000 can inhibit HT-29 proliferation and induce cell apoptosis by itself. The success of this strain's construction helped to inhibit migration and expansion of cancer cells, showing that the secretion properties of L. lactis of this particular peptide may serve as a new tool for cancer therapy in the ...
The Crabtree effect, named after the English biochemist Herbert Grace Crabtree, [1] describes the phenomenon whereby the yeast, Saccharomyces cerevisiae, produces ethanol (alcohol) in aerobic conditions at high external glucose concentrations rather than producing biomass via the tricarboxylic acid (TCA) cycle, the usual process occurring aerobically in most yeasts e.g. Kluyveromyces spp. [2 ...
