What is a peptide sequence?

Peptides are biological polymers consisting of an amino acid combination whose key elements are carbon (C), hydrogen (H), oxygen (O) and nitrogen (n). The term "peptide sequence" concerns the order in which the amino acids are connected. Peptides are very important in living systems and combine much larger chains called proteins. Although there are many varieties of biological peptides, most of which are made up of only 20 amino acids. Proteins perform a number of biological functions, including enzymes and in the structure of cell walls in plants and membranes in animal cells.

amino acids are called because they have amin (-nh _{2 ) and carboxylic acid (-Co 2 h). Most amino acids found in biological systems have a general R-CH formula (NH 2 )-CO 2 H, where r is a number of groups. The changing structure of R is what affects the structure and properties of peptides and proteins.y on another amino acid. The result is the formation of an amide group of structure -n (H) -Co-, where the carbon to the carbon is called a peptide bond. The reaction can take place at any time to form a peptide sequence of various functional groups, each of which is dispersed by an amide group.}

peptides and proteins have different levels of structure. The primary protein structure is the order in which amino acids are found; This is his peptide sequence. Functional groups on the protein interact with each other to pull them into shape. Individual twists and turns of peptide are called its secondary structure. Its overall shape, the net result of all these twists and turns, is a tertiary structure of the peptide.

Biochemical properties of proteins or peptides depend on tertiary structure. Jakos with all chemicals will assume proteins of the most general shape. This shape is caused by attractive and repulsive forcesbetween groups on individual amino acids. Therefore, the tertiary structure is caused by the primary structure, which means that the deduction of a peptide sequence of a particular protein will eventually explain its properties.

Peptide sequence of protein has an application in drug design. Many biological processes depend on the action of proteins and medicines often work by copying or blocking the effects of these proteins. Understanding the behavior of proteins could lead to more effective drugs. For this reason, the research and development department usually has a peptide library or a peptide catalog that it will use in the search for new drugs.
