Provided are a scroll preparing method using a two-dimensional material and a scroll prepared thereby. The scroll preparing method comprises preparing a two-dimensional material. The two-dimensional material is scrolled by providing an amphiphilic substance having a hydrophilic portion and a hydrophobic portion on the two-dimensional material. As a result, a scroll composite including the amphiphilic substance disposed inside a scroll structure is formed.

High Enantioselective and Large-Scale Production of Ursodeoxycholic Acid by Combination of Pd- and Hydroxysteroid Dehydrogenase-Catalyzed Hydrogenation
Ursodeoxycholicacid (UDCA) was synthesized from commercially available phytosterol-derived bisnoralcohol with an overall yield of 57% by a six-step process. The absolute configuration of the 3,5,7-stereogenic centers in UDCA was determined using Pd-catalyzed and hydroxysteroid dehydrogenase (HSDH)-catalyzed hydrogenation conducted under normal temperature and atmospheric pressure conditions. To investigate
