The basic building blocks of life are bio molecules. These complex molecules are responsible for the structure, function, and regulation of all living organisms. They include carbohydrates, lipids, proteins, and nucleic acids, each with unique properties that contribute to the incredible diversity of life on the planet [1,2].
Carbohydrates are carbon, hydrogen, and oxygen-containing organic compounds. They are a primary source of energy for living organisms, and they also play an important role in cell structure and communication [3,4]. Carbohydrates can be simple, like glucose, or complex, like starch and cellulose. Simple carbohydrates are found in foods like fruits, honey, and table sugar, while complex carbohydrates are found in grains, legumes, and vegetables [5].
Lipids are another type of organic compound that is necessary for life. They are composed of carbon, hydrogen, and oxygen, but they differ from carbohydrates in that they are not water-soluble. Lipids play a critical role in energy storage, cell membrane structure, and signalling pathways. Fats, oils, and waxes are all examples of lipids. Cholesterol, a type of lipid, is a crucial component of cell membranes and is also used to produce hormones and vitamin D [6,7].
Proteins are large molecules composed of amino acids. There are 20 different amino acids, each with a unique structure and function. Proteins are involved in nearly every aspect of cellular function, from structural support to enzyme activity to immune defence. Some proteins are also involved in the storage and transport of molecules throughout the body. Haemoglobin, for example, is a protein that transports oxygen in the blood [8,9].
Nucleic acids are the building blocks of DNA and RNA, the genetic material that controls the development and function of all living organisms. Nucleic acids are composed of nucleotides, which consist of a sugar molecule, a phosphate group, and a nitrogenous base. The four nitrogenous bases found in DNA are adenine, guanine, cytosine, and thymine. RNA contains uracil instead of thymine. The sequence of these bases determines the genetic code that specifies the sequence of amino acids in proteins [10].
Each of these four classes of biomolecules plays a unique role in the functioning of living organisms. Carbohydrates, for example, provide energy to fuel cellular processes, while lipids form the basis of cell membranes and protect organs from damage [11]. Proteins catalyze chemical reactions, support cellular structures, and facilitate communication between cells. Nucleic acids carry genetic information and control the expression of genes [12].
Beyond these basic functions, biomolecules are also involved in a vast array of biological processes. Enzymes, for example, are specialized proteins that catalyze specific chemical reactions within cells. Hormones, which are also made up of proteins, regulate numerous physiological processes in the body, from metabolism to growth and development. Nucleic acids, meanwhile, are involved in DNA replication, transcription, and translation, which are all critical processes for the maintenance and function of living organisms [13, 14].
Biomolecules are not static structures; they are constantly in motion, changing shape and interacting with other molecules in complex ways. The structure of a biomolecule determines its function, and even small changes to its structure can have profound effects on its activity. This is particularly true for enzymes, which are highly specific in the reactions they catalyze. Even small changes to the active site of an enzyme can render it inactive or alter its specificity [15].
Biomolecules also interact with the environment in complex ways. The folding and stability of proteins, for example, are influenced by factors such as temperature, pH, and the presence of other molecules. Lipids are also sensitive to environmental conditions, and changes in temperature or pressure can cause them to undergo phase transitions or form aggregates.
