We consider a liposome filled with the aqueous solution of an osmotic solute enclosed in a large water bath. Due to osmotic pressure, it works according to a sequence of cycles with two stages. In the first stage, the lipid vesicle with a certain inp

We have synthesized, beside the presently consecrated stress molecule, b-D-glucopyranosyl-cholesterol, b-D-arabinopyranosyl-, a-L-arabinofuranosyl- and b- and a-D-(3-O-methyl)glucopyranosyl-cholesterol. Two types of glycosylation agents were used: pe

Methylation of a hydroxy group annihilate or at least decrease the capacity of that group to form hydrogen bonds. The effect is still more pronounced by the reduction of a hydroxy group to a methylene (deoxy) one. The major methyl donor in the cells

Glycosylation acceptor, 4-nitrocatechol, has been prepared via 4-nitrocatechol sulfate (2-hydroxy-5-nitrophenyl sulfate). The two carbohydrates, D-xylose and lactose, were peracetylated and then served as glycosylation donors in a modified Helferich

Fischer’s approach for structure elucidation of linear aldohexoses is still the most widespread alternative in textbooks for carbohydrates. However, in post-Fischer era, a series of remarkable discoveries and inventions were made in different labor

Glycosides of 4-nitrocatechol (1,2-dihydroxy 4-nitrobenzene) with a-D-glucopyranose and a-D-mannopyranose were synthesized by the glycosylation of phenol with peracetylated sugars in the presence of BF3\cdot OBu2. The glycoside of 4-nitrocatechol wit
