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 […]

What are the transition elements? [ez-toc] Those elements, which have partially filled d or f-subshells in atomic state, are called transition elements. The d-block and s-block elements are transition elements because they are located between the s and p block elements. These elements are divided into two types. Outer transition elements Inner transition elements […]

What is the definition for Normality? The concentration of the solution expressed in a number of equivalent dissolved per liter of solution is known as the normality chemistry. Normality is represented by N. [ez-toc] Units of normality: Its units are eq/L or meg/L. The latter unit is mostly expressed in medical reporting. Formula of Normality […]

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 […]
