Histidine, phenylalanine leucine, valine, threonine, isoleucine, lysine, tryptophan, and methionine are some examples of essential amino acids. Alanine helps in the removal of toxic substances, cystine helps in the formation of skin, asparagine helps to balance the state of emotions, glycine is necessary for the healing of wounds, and proline helps in intracellular signaling.Ĭertain other amino acids need to be taken through diet, as they cannot be produced in the body, which are termed essential amino acids. Some of the non-essential amino acids are aspartate, alanine, asparagine, cysteine, glycine, arginine, proline, tyrosine, and serine. There are certain amino acids that are capable of being synthesized in the human body which are referred to as non-essential amino acids. Asparagine and glutamine are neutral amino acids.Īmino acids can also be further categorized into, If the number of amino and carboxylic acid groups is the same, then the amino acid is called neutral amino acids. Histidine and lysine are basic amino acids. If the number of amino acid groups is greater than that of the carboxylic acid groups, then the specific amino acid is termed a basic amino acid. Glutamic and aspartic acid are acidic amino acids. If the number of carboxylic acid groups is greater than that of the amino groups, then the amino acid is called an acidic category of amino acids.
Different types of amino acidsĪmino acids can be divided into three types, i.e., The amino acid polymers are interlinked by the peptide linkage.
These are generally water-soluble in nature and exhibit their character as salts. Amino acids are high melting solids that do not exhibit any color and exist as crystalline solids.

For example, glycine is represented as gly and G and proline is represented as pro and P. These are represented in three-letter and even in a single letter code. Enzymes are also an example of proteins which act as a catalyst in several biochemical reactions.Īmino acids are composed of two functional groups namely carboxyl and amino groups and they are differentiated as α, β, γ, δ, and so on. The alpha-amino acid biopolymers of subunits make up all the proteins, biologically. Proteins are classified as globular and fibrous proteins based on the shape of the molecule. Protein is an essential factor for the body’s maintenance and growth. This presents in all the body parts and is responsible for forming the basic structural and functional units of life. The main source of proteins is cheese, pulses, milk, fish, meat, and peanut. This particular biomolecule is available enormously in living organisms. Every biomolecule is made mainly of hydrogen and carbon atoms along with phosphorus, nitrogen, oxygen, and sulfur. Certain other simple molecules including minerals and vitamins also play their part in the composition of the organisms. The interaction between these kinds of essential biomolecules constitutes the molecular basis of the organisms. Specifically, carbohydrates and protein are the significant constituents of our food. Proteins, nucleic acid, carbohydrates, and lipids are a few of the complex macromolecules that make up the living species.
These atoms are interlinked by a covalent bond to form a molecule. Every organism that grows, reproduces and sustains their own life, are composed molecules and atoms that are non-living.
