Lysine

Amino acids are organic molecules, the monomers of proteins that contain both amino and carboxyl groups. Proteins of a cell mostly contain 20 types of amino acids that differ in the side chain known as R group. Therefore, the properties of the amino acid in protein fully depend on the characteristics of the side chains.

Lysine is an essential amino acid, that means it cannot be synthetized in the human organism. The side chain of the lysine molecule contains an additional amino group attached to the carbon skeleton. Because of the positive charge in the side chain, the charge ...

The amino acid is a hydrophobic and aromatic essential amino acid. The compound is relatively non-reactive because of the benzene ring in its structure. Since it is nonpolar, the amino acid does not dissolve in water. Due to its hydrophobic nature, the amino acid is buried in the hydrophobic core of protein structures. However, the aromatic side chain in the structure of the amino acid affects protein structure by staking with the aromatic side chains of other amino acids. The side chain of the amino acid is relatively non-reactive and as such is not often involved in the functions of ...

Abstract

Proteins are made up of amino acids and have major structural as well as functional roles in the body. Amino acid chains are synthesized from DNA sequences through transcription and translation. Proteins become fully functional only after co-translational or post-translational modification of the amino acid side chains and folding into appropriate three-dimensional conformations. Even slight changes in the DNA code could drastically alter the protein folding, alter its functioning, and eventually lead to certain diseases. Inherent cellular repair mechanisms, protein degradation pathways and molecular facilitators such as chaperones try to keep proteins in their native, stable conformation by acting ...

DNA and cancer treatment

Wade, N. (2010). Speed-reading of DNA may help cancer treatment. Retrieved on June 7, 2011, from The Johns Hopkins University has initiated a method of investigating the progress of a patient’s cancer treatment by means of modern technology for rapid succession, or decoding, huge quantities of DNA. The author in this article states clearly that individuals have a unit account of the DNA within their mitochondria, which are the several energy stores inside each cell. It states that apart form the mutations or modifications, in DNA present in cancer patients, even health individuals are known to have differences in ...
