The comprehensive scientific encyclopedia titled "Biochemistry and Molecular Biology" serves as an invaluable resource, addressing critical topics such as hormones, vitamins, amino acids, neurochemistry, protein biochemistry, cellular respiration, gene expression, and chemical pathology.

Biochemistry, often referred to as biological or physiological chemistry, delves into the chemical composition of living cells and organisms, alongside the biochemical processes that underpin vital life activities.

Molecular biology encompasses a range of biological sciences focused on understanding the storage, transmission, and execution of genetic information. It investigates the structure and functions of complex macromolecules that constitute cellular components, including irregular biopolymers such as proteins and nucleic acids. Methodologies employed in molecular biology include genetic engineering, cloning, and artificial expression. This discipline increasingly intersects with genetics, leading to the emergence of molecular genetics. Furthermore, the integration of computer technology into genetic analysis has given rise to innovative fields such as bioinformatics, genomics, and proteomics.

Molecular genetics specifically studies how variations in DNA structure or expression correlate with phenotypic differences among organisms. This area of research leverages insights from multiple biological disciplines including classical Mendelian inheritance, cell biology, molecular biology, biochemistry, and biotechnology. Researchers often seek or induce mutations within genes to establish associations between gene sequences and specific phenotypes.

Neurochemistry focuses on the intricate chemical processes occurring in the nervous system's function. It represents one of the most sophisticated and rapidly evolving sectors of biochemistry and neurobiology.

Biomolecules are organic compounds synthesized by living organisms, comprised primarily of proteins, polysaccharides, nucleic acids, and smaller metabolic components. The elemental composition typically includes carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur, with additional elements appearing less frequently in biologically significant substances.

Hormones are biologically active organic substances produced in specialized cells within endocrine glands. They enter the bloodstream and bind to receptors on target cells to regulate metabolism and physiological functions. Hormones act as humoral regulators for various processes occurring in different organs.

Vitamins encompass a group of low molecular weight organic compounds with relatively simple structures yet varied chemical natures. These substances are crucial for heterotrophic organisms as essential components of their diets; many vitamins function as coenzymes or precursors.

Enzymes are complex compounds composed of proteins or ribonucleic acid (RNA) that accelerate chemical reactions within living systems. Each enzyme adopts a specific conformation that catalyzes its corresponding reaction; substrates refer to the reactants in these reactions while products denote the resultant substances. Enzymatic activity is subject to regulatory mechanisms—activation by certain molecules known as activators or inhibition by inhibitors.

Amino acids are organic entities characterized by the presence of both carboxyl and amine functional groups. Approximately 500 naturally occurring amino acids are recognized; however, only 20 are utilized within the genetic code. Amino acids can be considered derivatives of carboxylic acids in which one or more hydrogen atoms have been replaced by amino groups.
