Neutral Amino Acids
Amino acids which do not have any charge on them are neutral amino acids.
Globular Protein
The globular proteins refer to the shape of protein specifically spherical in nature apart from spherical form fibrous, disordered and membrane-bound proteins exist. These globular proteins are miscible in water and form a colloidal solution rather than other types which might not exhibit solubility. Many classes of the fold are found in globular proteins, which render them a sphere shape. Globular fold containing proteins usually are referred to by the term globin.
Dimer
Dimers are basic organic compounds, which are derivates of oligomers. It is formed by the combination of two monomers which could potentially be strong or weak and in most cases covalent or intermolecular in nature. Identical monomers are called homodimer, the non-identical dimers are called heterodimer. The method by which dimers are formed is known as “dimerization”.
Dipeptide
A dipeptide is considered a mixture of two distinct amino acids. Since the amino acids are distinct, based on their composition, two dipeptide's isomers can be produced. Various dipeptides are biologically essential and are therefore crucial to industry.

Learning Goal:
Concentration is expressed in various ways in
second semester general chemistry. In this tutorial,
you will learn how to calculate concentration using
mole fraction and molality.
Part A - Using the definition for mole fraction.
A solution was prepared by dissolving 195.0 g of KCl in 225 g of water.
In your first chemistry course you learned about
expressing the concentration of solutes in solution
using molarity, the number of moles of a solute
per liter of solution. In this tutorial, we will review
Calculate the mole fraction of KCl. (The formula weight of KCl is 74.6 g/mol. The formula weight of water
is 18.0 g/mol.)
Express the mole fraction of KCl to two decimal places.
two other ways of expressing concentration, called
molality and mole fraction.
• View Available Hint(s)
The concentration of a solution can be expressed in
several different ways. Three common
concentration expressions are shown below:
Vο ΑΣφ
?
molarity (M) = moles of solute
liters of solution
X =
mole fraction (x) =
moles of component
total moles
moles of solute
molality (m) =
Submit
kg mass of solvent
Part B - Use the definition of molality
A solution was prepared by dissolving 195.0 g of KCl in 225 g of water.
Calculate the molality of KCl. (The formula weight of KCl is 74.6 g/mol. The formula weight of water is
18.0 g/mol.)
