The key difference between cysteine and cystine is that cysteine is an amino acid while cystine forms when two amino acids join together via a disulfide bond. An amino acid is a simple molecule formed with C, H, O, N and maybe S. There are about 20 common amino acids. All amino acids have a […]

The key difference between gelatin and pectin is that gelatin is a mixture of peptides and proteins, whereas pectin is a polysaccharide. Both gelatin and pectin are carbon-containing compounds. These compounds occur widely in living organisms; thus, it is very important to study their properties and nature. Moreover, these two compounds are thickening agents used […]

The key difference between coenzyme and cofactor is that the coenzymes are organic molecules, whereas the cofactors can be either organic or inorganic molecules. Enzymes are essential biological macromolecules. They are the biological catalysts, which increases the rate of biological reactions under very mild conditions. Moreover, enzymes are proteins; thus, when they are subjected to […]

The key difference between amino acid and nucleotide is that the amino acid is the building block of proteins while the nucleotide is the building block of nucleic acids. Macromolecule is a large molecule resulting due to polymerization of its monomers. The most common macromolecules found in living organisms including plants are nucleic acids (DNA […]

The key difference between amino acid and nucleic acid is that amino acids are the building blocks of proteins whereas nucleic acids are macromolecules made out of nucleotides. Proteins and nucleic acids are essential components in living organisms. They are macromolecules containing hundreds of repeating units. Hence, a repeating unit represents the monomers or the […]

The key difference between citric acid and ascorbic acid is that the ascorbic acid is the active compound in what we are taking as vitamin C whereas the citric acid is used in vitamin C tablets just for giving the taste. Citric acid and ascorbic acid are organic compounds, which can act as acids. Organic […]

The key difference between carbohydrates and proteins is that monosaccharides or simple sugars are the monomers of carbohydrates while amino acids are the monomers of proteins. Carbohydrates and proteins are two types of macromolecules. Furthermore, they are organic compounds composed of carbon, hydrogen and oxygen atoms. In addition, proteins contain nitrogen, sulfur and phosphorus. Both […]

The key difference between carbohydrates and lipids is that the carbohydrates are immediate energy sources in living organisms while the lipids act as a long-term energy resource and tend to be utilized at a slower rate. Carbohydrates and lipids are important nutrients in living organisms. They are organic compounds, and they serve as key sources […]

The key difference between glycogen and glucose is that glycogen is a polysaccharide that stores carbohydrates in animals and fungi while glucose is the most abundant monosaccharide that works as the primary source of energy in cells. Carbohydrates are organic compounds characterized carbon, hydrogen and oxygen elements. The ratio of hydrogen to oxygen is 2:1in […]
