INTRODUCTIONBiomolecules are very important in living organisms in this worlds. It Is very diverse in different ways. A biomolecule or biological molecule is a loosely used term for molecules or more commonly ions that are present in organisms. Biomolecules can be dividede into 4 major group which Is proteins, carbohydrates, nucleic acid, and lipids, besides there also the small molecules such as primary And secondary metabolite and also the natural products. As we know, biomolecule are organic compounds, and just four elements oxygen, carbon, hydrogen, and nitrogen which is make up 96% of the human body’s mass. In biomolecules there are some specifics metabolic pathways which is variant features between the diversity of life forms which us known as”theory of material unity of the living beings”. This is a concept in biology which Is along with the cell theory and also the evolution theory. The basics of biomolecules is known as monomers, which make a diverse array of larger polymers. Between the classes of biomolecules such as the protein, carborhydrates, lipids and nucleic acids, there is a facts that the monomers was used repeatly over again, and this Make them become more diverse as the result from mix or putting the monomer together differently.For example, the DNA ,the four nucleotides combined in different ways are the basis for all the diverse life forms on Earth. As well as Amino acid, only 22 amino acids serve as the common in order to bulid a block of protein structures.In all the biological molecules that has mention,monomer is assemble by dehyration synthesis.In this group study project, we will explain and focus more on how and why biomolecules are diverse. What to be discuss is biomolecules exist as isomers, how they can bond with others carbon in order to form chains, branched chains and ring. Then, the fuctional group,the varied bonding pattern and lastly about micromolecules and micromolecules.
