We begin our study of proteins by looking at the properties and reactions of amino acids, which is followed by a discussion of how amino acids link covalently to form peptides and proteins. We end the chapter with a discussion of enzymes—the proteins that act as catalysts in the body.

2021年10月1日 · Owing to the diversity of functional groups in amino acids, various polymerization methods may be used to make a wide range of well-defined functional amino-acid/peptide-based optically active polymers with varying polymer lengths, compositions, and …

Polymerization is a chemical reaction in which monomers link together to form long-chain molecules known as polymers. In the context of amino acids, this process occurs through dehydration synthesis, where a water molecule is removed to bond individual amino acids together. Here are the key points about this process:

Polymerization of a-Amino Acid N-Carboxyanhydrides Jianjun Cheng and Timothy J. Deming Abstract This chapter summarizes methods for the synthesis of polypeptides by ring-opening polymerization. Traditional and recently improved methods used to polymerize a-amino acid N-carboxyanhydrides (NCAs) for the synthesis of homo-polypeptides are described.

2015年6月3日 · To realize amino acid-based polymers as eco-friendly alternatives for petroleum materials, the synthesis of poly(amino acid)s/polypeptides through an environmentally friendly process is...

2020年6月23日 · This review focuses on the applications of polypeptides alongside the synthetic advances in the ring opening polymerization of α-amino acid N-carboxyanhydrides achieved in the past five years. Key architectures obtained through NCA ROP or in combination with other polymerization methods are reviewed, as these play an important role in the wide ...

All amino acids contain the -NH 2 group and also the carboxylic acid group -COOH. Amino acids are polymerised in cells to make. polypeptide A short polymer made from fewer than 50 amino...

2014年10月16日 · The polymerization of α-amino acid N -carboxy anhydrides (amino acid NCAs) is suitable for the synthesis of high molecular weight polypeptides with narrow molecular weight distribution. The polymerization is largely affected by the amino acid NCA purity and a moisture contamination in the reaction system.
