※ 引述《peter3752001 (手黑的脚白佑)》之铭言：
: polypeptide跟protein有什麽不同?
Proteins are polypeptide molecules
The distinction is that peptides are short and proteins are long.
Protein refers to the complete biological molecule, while peptide is a short
amino acid oligomer lacking in well-defined structure
Polypeptide refers to single linear chain of amino acids, implies an absence
of defined tertiary structure.
Most proteins fold into unique 3-dimensional structures
Biochemists often refer to four distinct aspects of a protein
简单来说,
一个 Protein molecule 是由无数个 polypeptide molecules 透过 condensation
reaction 形成的。
