Introduction to Biochemistry Applications Biochemistry, the study of chemical processes and substances within living organisms, is central to modern science and technology. Its applications extend far beyond academic research into practical domains such as medicine, agriculture, biotechnology, and industry. By understanding molecular mechanisms underlying life, biochemistry enables the development of drugs, vaccines, diagnostic tools, biofuels,…

Introduction Vitamins, hormones, and coenzymes are essential molecules that regulate numerous biochemical and physiological processes in living organisms. They do not serve as structural components of cells like proteins or lipids but act as regulators, catalysts, and facilitators of metabolic reactions. Their presence in precise amounts ensures the smooth functioning of metabolism, growth, development, and…

IntroductionMetabolism is the sum of all chemical reactions that occur within living organisms to maintain life. It encompasses processes that convert nutrients into energy and building blocks, regulate biochemical pathways, and support growth, reproduction, and cellular maintenance. Metabolic activities can be broadly categorized into two types: catabolism, the breakdown of molecules to release energy, and…

Enzymes are biological catalysts that accelerate chemical reactions without being consumed in the process. They are essential for nearly every biochemical reaction in living organisms, allowing cells to perform complex metabolic processes efficiently. Enzyme kinetics is the study of the rates at which enzyme-catalyzed reactions occur and how these rates are affected by various physical…

Introduction Nucleic acids are fundamental biomolecules that store, transmit, and express genetic information in all living organisms. They are polymers composed of nucleotides, which consist of a nitrogenous base, a sugar, and a phosphate group. The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA holds the genetic blueprint…

Introduction to Lipids Lipids are a diverse group of naturally occurring organic compounds that are hydrophobic or amphipathic in nature, meaning they are insoluble in water but soluble in nonpolar solvents such as chloroform, ether, and acetone. They are fundamental components of living organisms, playing crucial roles in energy storage, cellular structure, signaling, and metabolism.…

Introduction Proteins and enzymes are fundamental molecules that drive virtually all cellular processes. Proteins are large, complex molecules composed of amino acids, which fold into specific three-dimensional structures to perform diverse biological functions. Enzymes, a specialized class of proteins, function as catalysts, accelerating biochemical reactions without being consumed in the process. Understanding proteins and enzymes…

IntroductionCarbohydrates are one of the fundamental classes of biomolecules, essential to life. They are organic compounds composed of carbon, hydrogen, and oxygen, typically in a ratio of 1:2:1 (CH₂O). Carbohydrates serve as a primary energy source, structural components, and participants in various biological processes such as cell signaling and recognition. They are widely distributed in…

Living organisms, from the simplest bacteria to complex humans, are composed of biomolecules. These molecules are fundamental components of cells and are essential for the structure, function, and regulation of life processes. Biomolecules include carbohydrates, lipids, proteins, and nucleic acids, each serving specific roles that sustain life. Understanding these molecules provides insight into how organisms…

Definition of Biochemistry Biochemistry is the branch of science that studies the chemical processes and substances that occur within living organisms. It is an interdisciplinary field that bridges biology and chemistry to explain life at the molecular level. Biochemistry focuses on understanding the structures, functions, and interactions of biomolecules, including carbohydrates, proteins, lipids, nucleic acids,…
