Question

Briefly explain an example of an Amino Acid Sequence.

Answer 1

Hint: Amino acids belong to a class of organic particles that consists of a basic amino group, an acidic carboxyl group, an organic R group—or side chain—and a central carbon atom. Amino acid sequencing is the process of detecting the arrangement of amino acids in peptides and proteins. Several different amino acids were found in nature but all proteins in the human body are made up of just twenty different kinds.

Complete step-by-step answer:
The arrangement of amino acids in a protein is called an amino acid sequence. Proteins can be produced from 20 different types of amino acids, and the function and structure of each protein are defined by the types of amino acids used to make it and how they are organised. The amino acid sequence indicates protein molecules that are made of strings of amino acids in a specific sequence. It contains amino acids like serine, lysine, and valine, and these amino acids are arranged in a specific sequence. Amino acid sequences can be written by using either a one-letter code or a three-letter code. The accurate formating of sequences differs according to the application; according to the rules single letter codes are always capitalised. The amino acid sequence of a peptide or protein is useful information to identify the peptide or protein, distinguish it in a sample and classify its post-translational modifications. The process of defining the amino acid sequence is called protein sequencing.

Note: The sequence of amino acids as arranged in sheets, chains, etc., within the protein molecule. This is called the primary structure of proteins. It is of primary importance in defining the protein conformation. There are two main ways of amino acid sequencing: mass spectrometry and Edman degradation with a protein sequenator.
