Haemoglobin Definition: Hemoglobins are an iron-containing protein in the blood of many animals in the red blood cells (erythrocytes) of vertebrates that transports oxygen to the tissues. Haemoglobin forms an unstable, reversible bond with oxygen. In the oxygenated state, it is called oxyhaemoglobin and is bright red; in the reduced state, it is purplish blue. Heme is a prosthetic […]

There are four different types of structures of proteins. The 20 amino acids commonly found in proteins are connected together by peptide bonds. The linear sequence of these amino acids encodes the information required to produce a protein molecule with a unique three-dimensional structure . Primary structure Secondary structure Tertiary structure Quaternary structure [ez-toc] Primary […]

Qualitative test for Carbohydrates The qualitative tests for carbohydrates such as (Molish, Benedict, Fehling, Osazone, and Barfoed tests) are used to detect the presence of reducing and non-reducing, mono and disaccharides in a sample. Here are common qualitative tests for carbohydrates: EXPERIMENTAL ANALYSIS 1. Molish Test The molish test is a simple, rapid, and […]

Sample collection The process of acquiring tissues, fluids, any other sample, or material for laboratory analysis is called the sample collection process. For example, if we want to analyze the protein source, it will be eggs because eggs contain a high amount of protein, which will be our sample of analysis. This involves many things that […]

Centrifugation “Centrifugation is a technique to separate particles and components (biomolecules) suspended in a liquid medium”. [ez-toc] How does centrifugation work Centrifugation works on the principle of sedimentation( formation of layers). “The principle of the sedimentation technique is to separate particles suspended in the liquid under the influence of centrifugal force according to their density.” […]

Size Exclusion Chromatography In size exclusion chromatography ( molecular or gel filtration or gel permeation chromatography), molecules, and particles are separated. Small molecules penetrate the pores of the stationary phase, but large molecules do not. Because small molecules must pass through an effectively larger volume, large molecules are eluted first. This technique is widely used […]
