Biochemical Analysis Techniques

Introduction

Biochemical analysis techniques are powerful tools used in chemistry and biochemistry to study the composition and function of biological molecules. These techniques allow scientists to identify, quantify, and characterize various biomolecules, such as proteins, lipids, carbohydrates, and nucleic acids. By analyzing these molecules, researchers can gain insights into cellular processes, disease mechanisms, and potential therapeutic targets.

Basic Concepts

• Sample Preparation: Preparing samples for biochemical analysis involves extracting and purifying biomolecules from various biological sources, such as cells, tissues, or fluids.
• Separation Techniques: Techniques like chromatography and electrophoresis are used to separate biomolecules based on their size, charge, or other properties.
• Analytical Methods: Spectrophotometry, fluorimetry, and mass spectrometry are common methods used to quantify and characterize biomolecules.

Equipment and Techniques

• Spectrophotometer: Measures the absorption or emission of light by biomolecules at specific wavelengths.
