¿Qué es Chitosan Oligosaccharide (COS) Agrícola Elicitor? Aplicaciones, dosis, alternativas y especificaciones

Chitosan Oligosaccharide (abbreviated as COS), also known as Chitosan Oligomer, Bajo Molecular Weight Chitosan, Chitooligosaccharide, and Agrícola Aminoglycan, es un natural oligosaccharide product obtained by degrading chitin or chitosan, con una degree of polymerization (DP) between 2 and 20. It is produced from abundant marine biological resources (shrimp and crab shells) through decalcification and deproteinization to obtain chitin, deacetylation of chitin to obtain chitosan, and then degradation of chitosan through biological enzymatic hydrolysis (or chemical degradation, physical degradation, y otros methods). Chitosan oligosaccharide is the only cationic alkaline amino oligosaccharide carrying a positive charge in nature, known as “animal cellulose,” and es una upgraded product of chitin and chitosan products. In biological systems, chitin has a molecular weight of ≥1000 kDa, is insoluble en agua and general acid and alkaline solucións, and es unlmost not absorbed by the body; chitosan has a molecular weight of ≥100 kDa, is only soluble en dilute acid solucións, with 1–3% absorption; while chitosan oligosaccharide has a molecular weight of ≤3000 Da, is easily soluble en agua and acid and alkaline solucións, with over 99% absorption by the body. Chitosan oligosaccharide possesses unique functions como the high solubility that chitosan lacks, complete water solubility, easy absorption and utilization by living organisms, with its effect being 14 times that of chitosan. Chitosan oligosaccharide products are disponible in various forms, incluyendo different degree of polymerization specifications (chitobiose to chitoeicosaose, etc.), different molecular weight specifications (≤3000 Da), different pureza grades (agricultural grade, grado alimentario, cosmetic grade, pharmaceutical grade), así como polvo and líquido formulations.

Chitosan oligosaccharide is an oligosaccharide composed of 2–20 glucosamine units connected by β-1,4 glycosidic bonds. Its molecular formula can be expressed as (C6H11NO4)n (n=2–20), and its chemical name is β-(1,4)-2-amino-2-deoxy-D-glucan. The main activity of chitosan oligosaccharide depends on its degree of polymerization distribution, degree of deacetylation, and molecular weight. Based on its molecular structure, it can be divided into three types: α, β, and γ. Típicoly, a degree of deacetylation ≥85% is considered chitosan oligosaccharide, while a degree of deacetylation ≤15% is considered chitin oligosaccharide. Parámetro
