Polypeptide chain composed of multiple amino acid residues in sequence
The carboxyl terminal consists of multipleAmino acid residuePolypeptide chains formed in a certain order usually contain a free α - amino at one end, called the amino end or the N end A or N end, and the other end contains a free α - carboxyl, called the carboxyl end or the CA end or the C end.
Chinese name
Carboxyl terminal
Properties
Biological terminology
application
Peptides are named according to their compositionAmino acid residueIt is specified that starting from the amino terminal amino acid residue of the peptide chain, it is called a certain amino acid. For example, a pentapeptide with the following chemical structure is named serine glycyl tyrosine alanyl leucineSerGlyTyrAlaLeu。Generally, A always places the amino terminal amino acid residue on the left and the carboxyl terminal amino acid residue on the right, unless otherwise specified. If the pentapeptide in the above example is written in reverse, leucine is written on the left and serine is written on the right, it will become another different pentapeptide LeuAlaTyrGlySer.AAAA related terms: By a number of amino acid residues composed of a certain sequence of polypeptide chain,usually at one end containing a free α-amino-acid called N-terminal or N terminal or N terminal end of A and the other end containing a free α-carboxyl group, saying for the carboxy-terminal end or C terminal, or CA. peptide involved in its name is based on the composition of amino acid residues to determine,the provisions of peptide chain from the N-terminal amino acid residues starting, called an aminoacyl certain amino acids, etc.. For example, with the following chemical structure of the 5 peptides, named seryl glycyl tyrosyl alanyl-leucine. SerGlyTyrAlaLeu. A usually always N-terminal amino acid residues on the left,carboxyl-terminal amino acid residues on the right side, in particular, pointed out that those other countries. Above example, the five peptides, if in turn, writing, written on the left side of the leucine and the serine written on the far right,it becomes a different five-peptide LeuAlaTyrGlySer.
