Though proteins can be stored with cosolvents such as salts and polyols to enhance their stability and activity for biological and biotechnological applications, however, the mechanisms for protein stability remain elusive. Generally, these cosolvents promote the shifting of protein conformations towards more compact form and prevent …
Structure of Hemoglobin, a Hetero-tetramer Protein Hemoglobin is a protein containing non-protein prosthetic group ‘heme’ and protein parts, globulin proteins. Heme is an iron-containing prosthetic group composed of a porphyrin ring structure on which one iron atom is located centrally. Hemoglobin is a heterotetramer protein with …
Proteins associated or embedded in a biological cell membrane are called membrane proteins. Membrane proteins are of two types. Integral Proteins Proteins that are embedded deeply in the plasma membrane are integral proteins. They are held inside the membrane by hydrophobic interaction. Integral proteins may have …
Ion channels are membrane proteins that belong to the membrane transport proteins located in the cell membrane. They are conjugated proteins and serve as a transporter of ions. Charged atoms like Na+, K+, Cl– cannot pass through the cell membrane because the cell membrane is impermeable …
What is Glutathione and How is it Synthesized in our Body? Glutathione (GSH) is a tripeptide of glutamate, cysteine, and glycine. However, the peptide bond between glutamate and cysteine is not a normal peptide bond but is a pseudo-peptide bond (peptide bond formed not by the α-carbonyl …
If you are asking yourself about how many different kinds of proteins does a single cell contains, then you must read this article. This article will explain to you in detail. Proteins are the polymers of amino acids in which amino acids are linked together through …
