The key difference between nucleotide and nucleoside is that the nucleotide contains a phosphate group while the nucleoside lacks a phosphate group. Nucleosides and nucleotides are a similar type of molecules that differ by a slight structural change. Both nucleotide and nucleoside are composed of same two components; a pentose sugar and a nitrogenous base. […]

The key difference between good cholesterol and bad cholesterol is that good cholesterol removes other forms of cholesterol from our bloodstream, reducing the risk of heart diseases while bad cholesterol builds up within the walls of our blood vessels, narrowing them and causing heart attacks and strokes.  The rise in non-communicable diseases all over the […]

The key difference between oxidases and oxygenases is that the oxidases are the enzymes that catalyze the oxidation-reduction reactions by transferring the hydrogen from a substrate to oxygen, and thus, forming water or hydrogen peroxide while, the oxygenases are the enzymes that catalyze direct incorporation of the oxygen from the molecular oxygen (O2) to a […]

The key difference between tonicity and osmolarity is that the tonicity measures only the concentration of non-penetrating solutes through a semipermeable membrane while the osmolarity measures the total concentration of penetrating and non-penetrating solutes. Osmolarity is the measure of osmotic pressure of a solution. In simpler terms, it is roughly the measure of the amount […]

The key difference between cholesterol and triglycerides is that cholesterol is essential to build cells and certain hormones while triglycerides store unused calories and provide us with energy. Triglycerides and cholesterol are two types of lipids (fats) that are important for our life. However, in excess, they may cause health problems. Triglyceride is an ester […]
