A Natural Indicator is a chemical compound that helps us determine whether the nature of a particular substance is acidic or basic, by changing its colour. The most common natural indicator is a litmus, which is extracted from the lichens. It is purplish in colour in distilled water. When it...
Material and methods In 2018, a retrospective study was conducted analysing the different compounded formulas and amount of preparations, comparing data with the hospital formulary and classifying them according to specific therapeutic groups, in line with the anatomic, therapeutic, chemical classification ...
In science, thermal energy defines the kind of energy produced due to the variation in the temperature of a chemical substance or a system. Due to the variation in the temperature of a chemical substance, the molecules or atoms of it moving, and impact with one another, and cause thermal ...

Figure 2. Structural formulas of phosphorylated thiamine derivatives Thiamine monophosphate (TMP) is usually present in cells in low concentrations and is considered to be biologically inactive. The highest concentrations of TMP in relation to total thiamine and its phosphorylated derivatives are found in...
An element is composed either of an individual atom or molecules made of this atom. It has its own fixed melting and boiling points. An element cannot be broken down into simpler substances by any physical or chemical means. An element may chemically react with another element or compound. ...
Kamalak (2006) has studied the nutritive values ofG. glabraleaves, hand harvested at prebud, mid, and late flower stages from three plots. He has evaluated this in terms of chemical composition, in vitro gas production, and in situ dry matter (DM) and crude protein (CP) degradation. As...
