Peptide And Protein Differences

Amino acids, peptides, and proteins are often referred to as the terms are interrelated, but they are different in their characteristics. Amino acids are the building blocks of peptides and proteins. Amino acids are small molecules that contain an amino group (-NH2) and a carboxylic acid group (-COOH), which is attached to the central carbon atom, with the addition of hydrogen and a side chain (R group). The side chains vary among all of the amino acids; because it determines the unique character and chemistry of each amino acid. Specific gene sequences that are used to determine the sequence of amino acids in both peptides and proteins. Both peptides or proteins contained in the GHRP 6.

Proteins are the most diverse group of biological macromolecules. A protein consisting of one or more long branched chains called polypeptides and protein constituents of the previous is an amino acid. The sequence of amino acids determines the main characteristics of the protein, while the amino acid sequence is defined by a specific gene sequence. Usually, proteins have a stable three-dimensional structure. This structure can be discussed in terms of hierarchy into four levels; primary, secondary, tertiary and quaternary. The main structure is the amino acid sequence of the protein. The secondary structure is produced by forming hydrogen bonds between two amino acid nearby, resulting in a structure called ß-plated sheets, and coils called a-helices.
