Digestion: Digestion is the process by which food is broken down into smaller molecules that can be absorbed and utilized by the body. It occurs in several stages, primarily within the gastrointestinal tract, involving mechanical and chemical processes. 1. Mechanical Digestion: Mechanical digestion involves the physical breakdown of food into smaller particles, increasing its surface […]
Introduction: Medicinal chemistry is a multidisciplinary field that combines principles of chemistry, biology, and pharmacology to discover, design, develop, and optimize small molecule compounds for therapeutic use. It plays a pivotal role in the discovery and development of drugs to treat various diseases, ranging from infections to cancer. This note aims to provide a detailed […]
Pharmacokinetics refers to the study of how drugs move through the body. It involves several key processes including membrane transport, absorption, distribution, metabolism, and excretion. Understanding these processes is crucial for predicting how drugs will behave within the body, determining appropriate dosages, and optimizing therapeutic outcomes. 1. Membrane Transport Membrane transport is how drugs cross […]
Digestion involves breaking down food into smaller components for cellular absorption and utilization. Absorption is the uptake of these components into the bloodstream or lymphatic system for distribution to cells. The gastrointestinal tract (GIT) is where most digestion and absorption of nutrients occur. Here’s an overview of the processes for different macronutrients: 1.Carbohydrate: 1. Digestion: […]
