The change of the relative numbers of the polar and non-polar amino-acids as a result of a mutation must produce big changes in the protein structure.

Polar Amino Acids: These amino acids have side chains that are hydrophilic and can form hydrogen bonds with water.Examples include serine, threonine, cysteine, asparagine, and glutamine. Non-Polar ...

This is known as a hydrogen bond, and occurs between amino acids which have what is called a polar side-chain. Hydrophobic Interactions Some amino acids have side-chains which repel water, or are ...

Amino acids that fall under the classification of hydrophobic are alanine, valine, isoleucine, leucine, methionine, phenylalanine, tryptophan and tyrosine. As their classification suggests, the side ...

Together, these non-polar amino acids cause a hydrophobic interaction that produces the elastic properties of elastin. They include: Proline is a water-repellant amino acid that is also abundant ...

Amino acids are the building blocks that form polypeptides and ultimately proteins. Consequently, they are fundamental components of our bodies and vital for physiological functions such as protein ...

The mRNA specifies the sequence of the amino acids. Each amino acid within this polypeptide chain has a different property. For example, glycine is highly hydrophobic, whilst arginine is very ...
