Biochemistry is one of the branches of natural sciences and is concerned with the study of the chemical composition of cell parts in various living organisms, whether they are simple organisms such as bacteria, fungi, and algae, or complex organisms such as humans, animals and plants. Biochemistry is sometimes described as the science of life chemistry, because biochemistry is related to life. Scientists in this field have focused on researching chemical reactions within living organisms of all kinds by studying the cellular components of these organisms in terms of the chemical structures of these components, their locations and their vital functions. As well as studying the various biological reactions that occur within these living cells in terms of construction and composition, or in terms of demolition and energy production. Which greatly helps in understanding the tissues, organs and functions of living organisms.
