Biological macromolecules are the focus of biochemistry, which examines their structures and their roles in living organisms. Protein, lipids, nucleic acids, and carbohydrates are all examples of macromolecules found in your body. Thus, biochemistry is being employed in studies in fields such as pharmacology, medicine, and genetic engineering. The modern field of biochemistry seeks to unlock the mystery of life by elucidating how molecules of life support cellular activity. Proteins, carbohydrates, nucleic acids, and lipids all contribute to cell structure and function, and as such, biochemists spend a lot of time studying their functions, structures, and interactions. In addition to the reactions of larger molecules and ions, the chemistry of a cell also relies on those of the smaller molecules and the ions. These might be inorganic, like water or metal ions, or organic, like the building blocks of proteins known as amino acids. Metabolism refers to the processes through which organisms get energy from chemical reactions. The fields of nutrition, medicine, and agriculture benefit most from biochemistry's discoveries. Biochemists work to discover new treatments for, and potential prevention of, illness. The field of nutrition investigates the relationship between poor diet and negative health outcomes. Biochemists work in the agricultural sector by studying soil and fertilizers to find new methods of growing plants, preserving harvests, and preventing insect infestations. Proteins, lipids, carbohydrates, nucleic acids, and other biomolecules make up a large portion of the focus in biochemistry, as do their respective structures and functions; however, the emphasis is shifting away from studying individual molecules and toward studying the processes that these molecules participate in.
