Biological molecules originate from a variety of sources, primarily through natural processes on Earth. They are synthesized by living organisms via metabolic pathways that convert simple inorganic compounds into complex organic molecules, such as carbohydrates, proteins, lipids, and nucleic acids. Additionally, biological molecules can also arise from abiotic processes, such as those thought to have occurred on early Earth, where simple molecules combined under certain conditions to form more complex structures. Overall, they are integral to the structure and function of all living organisms.
The biological processes
Biochirality is the chirality - of biological molecules, especially the study of the genesis of such chirality - the phenomenon by which two biological molecules are symmetrical.
Large biological molecules typically form covalent bonds to create stable structures. These bonds involve the sharing of electrons between atoms, providing strength and stability to the molecules. Examples of covalent bonds in biological molecules include peptide bonds in proteins and phosphodiester bonds in nucleic acids.
Carbon is the main element found in biological molecules. It can form stable bonds with a variety of other elements, allowing for the diversity and complexity of molecules necessary for life.
Biological molecules are made through a process called biosynthesis. This involves the synthesis of complex molecules by living organisms, using enzymes and metabolic pathways to build molecules such as proteins, carbohydrates, lipids, and nucleic acids. These molecules are essential for the structure, function, and regulation of cells and organisms.
Proteases originate from cells in biological systems. They are enzymes that help break down proteins into smaller molecules.
The biological processes
The carbohydrate molecule is often referred to as the backbone of biological molecules as it is essential for storing and providing energy. However, carbohydrates are often not represented in diagrams of biological molecules for simplification purposes.

Examples of covalent bonds in biological molecules include peptide bonds in proteins and phosphodiester bonds in nucleic acids.
Biological molecules are primarily joined by covalent bonds. These bonds involve the sharing of electron pairs between atoms and are strong and stable, allowing biological molecules to maintain their structure and function.
Organic molecules contain carbon.
enzymes are protein molecules that act as biological catalysts
Carbon
The properties of matter originate from the arrangement and interactions of atoms and molecules within the substance.
