Creative Proteomics an advanced technology platform, including high-performance liquid chromatography/gas chromatography technologies combined with mass-spectrometric technique, to accurately and efficiently analyze and quantify proline content in plants and annimals. This high-throughput approach is helpful to further explore the applications of 5-hydroxylysine in annimal and plant development.

Overview

Lysine (Lys) is an indispensable amino acid nutrient essential to the human body. 5-Hydroxylysine is the most important one. Because the content of lysine in cereal foods is very low and it is easily destroyed and lacked during processing, it is called the first limiting amino acid. 5-Hydroxylysine can prevent bone loss (which can cause osteoporosis), promote human development, enhance immune function, improve central nervous system function, and treat migraine and abdominal cramps related to premenstrual syndrome and menarche Pain, improve the absorption and utilization of food protein, and achieve balanced nutrition. 5-Hydroxylysine plays an important role in the body weight of humans and animals, but little is known about its role in plant cells or animal cells under different growth conditions. Fortunately, high performance liquid chromatography or gas chromatography can be used to detect and quantify specific amino acids based on their physical and chemical properties. Combined with mass spectrometry, specific amino acids such as 5-hydroxylysine in different plant or animal samples can be effectively determined.
