Biochemistry is the scientific discipline that studies chemical processes in living organisms at the molecular level. It comprehensively examines the building blocks of cells, their interactions, energy transformations, and all biochemical reactions necessary for sustaining life. Biochemistry is one of the foundational pillars of modern scientific understanding, intersecting with numerous disciplines including chemistry, biology, physics, medicine, and engineering.Historical Development and Scie

You want to lose weight, you stick to your diet, and perhaps you even go to the gym regularly, yet the scale stubbornly keeps showing the same weight. You wonder where you are going wrong. Here is the answer: sleep deprivation.Inadequate sleep, now an unavoidable part of modern life, can be the invisible enemy of your weight loss efforts. Today’s individuals have begun stealing sleep between screen-filled nights, demanding work schedules, stress, and social commitments. Yet our bodies—especially

Histidine (His or H) is one of the standard 20 amino acids that serve as fundamental building blocks of proteins in living organisms. It plays a vital role in structural integrity and functional diversity due to its unique chemical and biological properties. In humans, it is considered an essential amino acid, meaning the body cannot synthesize sufficient quantities and it must be obtained through the diet. The most distinctive feature of histidine is its imidazole side chain, which has a pKa va

Thrifty Gene Hypothesis is a biological model that attributes the susceptibility to obesity and type 2 diabetes in modern human populations to evolutionary adaptations. It was first introduced in 1962 by American geneticist James V. Neel to explain the evolutionary basis of diabetes.Layla Brassington vd., “Integrating the Thrifty Genotype and Evolutionary Mismatch Hypotheses to Understand Variation in Cardiometabolic Disease Risk,” Evolution, Medicine, and Public Health 12, no. 1 (2024): 214, er

Vitamins are organic compounds essential for maintaining physiological functions, normal growth, and development. They play a role in regulating biochemical reactions in the body. Some vitamins function as coenzymes while others exhibit hormone-like effects. Different vitamins occur naturally as components of various foods. Although they do not provide energy, they must be obtained from external sources to ensure optimal biological processes. Insufficient levels in the body disrupt biochemical r

The pancreas is a mixed-function gland that maintains the body's metabolic balance by producing both endocrine (hormone) and exocrine (enzyme) secretions. Although difficult to study due to its deep location, the physiology of the pancreas is now well understood.Physiology of the PancreasThe pancreas is a mixed gland that secretes both endocrine and exocrine secretions and plays a vital role in the regulation of metabolic processes.  Exocrine FunctionThe majority of the pancreas (98-99%) consist
