Trehalose is a nonreducing sugar formed from two glucose units joined by a 1–1 alpha bond, giving it the name α-D-gluco pyranosyl-(1→1)-α-D-gluco pyranoside. The bonding makes trehalose very resistant to acid hydrolysis , and therefore is stable in solution at high temperatures, even under acidic conditions.
Indeed, three are the atoms in the middle layer (inside the prism); in addition, for the top and bottom layers (on the bases of the prism), the central atom is shared with the adjacent cell, and each of the six atoms at the vertices is shared with other six adjacent cells. So the total number of atoms in the cell is 3 + (1/2)×2 + (1/6)×6×2 = 6.
Mass fraction can also be expressed, with a denominator of 100, as percentage by mass (in commercial contexts often called percentage by weight, abbreviated wt.% or % w/w; see mass versus weight). It is one way of expressing the composition of a mixture in a dimensionless size ; mole fraction (percentage by moles , mol%) and volume fraction ...

1. Synthesis of methylcholanthrene. First 3-MC was synthesized with the method of reference. [5] Later the synthesis of the compound was improved. [6] [7] The synthesis of 3-MC consists of a few steps, visualized in figure 1; the first step is the key to success for the synthesis. 4-methylindanone (1) reacts in condensation with lithium salt of N,N-diethyl-1-naphthamide (2).
