What is RNase? What is the importance of living things?

ribonuclease enzyme

RNase means Ribonuclease. It is RNA digesting enzyme. It is another noteworthy example of a protein with a tertiary structure.  Let us see the basic details now. The molecular weight of RNase is 13,700. Christian Anfinsen (1950) and William stein (1958) have elucidated the complete structure of this pancreatic protein. RNase consists of 124 amino acids in one polypeptide chain …

What is Myoglobin? What is the function of Myoglobin?

myoglobin structure

One of the most important proteins in the human body is MYOGLOBIN (symbol as MB or Mb). Today we are discussing Myoglobin in this post. It found in muscle tissue, where it binds oxygen, helping to provide extra oxygen to release energy to power muscular contractions. Let us come to the history of Myoglobin. It was the first protein they determined whose structure. In 1958, Max …

How the Tertiary structure of Protein is Organized closely?

tertiary structure of proteins

Do you know the tertiary structure of proteins? All Globular Proteins are tertiary proteins. These have consisted of a small helix and elongated structures with considerable length and small cross-sectional area. In the Globular protein formation, few of the bonds are involved. They are Hydrogen bonds, disulfide bonds, hydrophobic interactions, and ionic interactions. This is a very compact three-dimensional structure, …

What is the Secondary Structure of Protein, Types and Organization?

Secondary Structure of proteins

Secondary Structure of Protein Organizational assumption points are No rotation occurs around the peptide bond (as it is partly double-bonded in nature). The chain of amino acids forms a rhythmical structure – forming a repeating pattern. That the maximum number of interactions from Hydrogen bonding possible are occurring, independent of the type of residue (amino acid). Basic explanation of the …

Protein Structure: Primary Structure of proteins

Protein Structure: Primary Structure of proteins

The peptide bond , strong, is responsible. It has adjacent atoms in the same plane where the fact that it is coplanar  and Linear molecule. It has a partial double bond character of resonance between two forms. This confers it an almost full strength. The rotations are absent and there are two possible conformations for binding:. Cis or trans This …

What are the Stabilizing Bonds Involved in Proteins?

Stabilizing Bonds involved in protein structure

Are you looking for information about Stabilizing bonds in protein structure? Proteins are vital macromolecules at both cellular and systemic levels, but they rarely act alone. Diverse essential molecular processes within a cell are carried out by molecular machines built from a large number of protein components organized by their Protein-Proteins interaction (PPI). Indeed, these interactions are at the core of the …

What are Proteins and classification of proteins?

Proteins classification

Do these notes explain What is Protein and the classification of proteins in Biochemistry? The proteins are the cellular macromolecules most abundant constituting 60% of the dry weight of cells. They consist of one or more polypeptide chains and has a molecular weight greater than 10,000. They have a unique and diverse structure. The polypeptide chains fold more or less heavily …

Amino acids – Proteins (Basic Overview)

Amino acids and proteins overview

we are studying only about 20 amino acids, there are about six more found in the body. Many others are also known from a variety of sources. Amino acids are the building blocks used to make proteins and peptides. The different amino acids have interesting properties because they have a variety of structural parts which result in different polarities and …
