Introduction The atmosphere is the only source of nitrogen with a total amount of about 78%. The nitrification process is one of the steps of the nitrogen cycle. This nitrogen is the most essential element for all living organisms. This nitrogen circulates from the atmosphere to the biosphere and again from the biosphere to the

Introduction Besides glycolysis, the carbohydrate can be metabolized by the pentose phosphate pathway. Different types of food items are digested in the nutrition system and turned into simple food. Simple food is absorbed by the small intestine flows through the bloodstream to different cells and becomes part of the protoplasm. The absorbed food reaches various

Introduction Glycolipids are the component of the cell membrane. Only 5% of lipids in the cell membrane are glycolipids. Lipids are an important biochemical compound in plants and animals, consisting of carbon, hydrogen, and oxygen. The main function of lipids is to store energy and act as components of cell membrane formation. According to the

Introduction N-terminus is a residue in a peptide that has an amino group (-NH₂). Amino acid is an essential component of protein. Each amino acid contains at least one amino group (-NH₂) and one carboxyl group (-COOH). The polymers of amino acids are peptides. A peptide is linked by Peptide bonds between the amino group

Introduction Peptide bonds are the linkage or attachment of one amino group and one carboxyl group from amino acids. Amino acids are the building blocks of proteins. Protein is the main component of human body cells. These acids are obtained by splitting large protein molecules into smaller ones. Amino acid is an essential component of

Introduction Amino acids are ionized in an aqueous solution. Those alpha-amino acids having a single amino group and a single carboxyl group crystallize from neutral aqueous solutions as fully ionized species, known as a zwitterion. It is an inner salt. It is mainly caused by an aqueous solution of amino acids. The –COOH and -NH₂

Introduction Lipids are naturally occurring molecules comprising a large group of compounds that are soluble in an organic solvent like chloroform, ether, or benzene, but poorly soluble in water. These biomolecules consist of carbon, hydrogen, and oxygen. Lipids have been classified into simple lipids, compound lipids, and steroids. Sphingomyelins are a type of compound lipids

Introduction Purine and pyrimidine are the two nitrogenous bases known as the building blocks of nucleic acids in both DNA and RNA. Besides being nitrogenous bases there are some differences between them so we will discuss purines vs pyrimidines. Nucleic acid is basically a polymer of countless nucleotides. Nucleotides consist of three subunit molecules, such

Introduction Nucleic acid is a polymer-type chemical that regulates the various biological functions of an organism. It is basically a polymer of nucleotides. Three types of components are found after hydrolysis of nucleic acid namely pentose sugar, nitrogenous bases, and phosphoric acid. Guanine is a type of nitrogenous base (5). These nucleic acids are the
