Inulin is a naturally occurring polysaccharide complex carbohydrate composed of fructose, a plant-derived food that human digestive enzymes cannot completely break down. The inulins belong to a class of dietary fibers known as fructans .
Pectin lyase is a polysaccharide enzyme with a complex structure that is present in plant cell walls. It has a significant role in pectin degradation and different biotechnological and industrial applications. It can be found in many different organisms. [1]
This enzyme belongs to the family of lyases, specifically those carbon-oxygen lyases acting on polysaccharides. The systematic name of this enzyme class is hyaluronate lyase . Other names in common use include hyaluronidase ( ambiguous ), (hyalurononglucosaminidase) ( ambiguous ), (hyaluronoglucuronidase)] , glucuronoglycosaminoglycan lyase ...
HA, a linear polysaccharide, is composed of repeating disaccharide units of →4)GlcAβ(1→3)GlcNAcβ(1→ and has a very high molecular mass, ranging from 10 5 to 10 7 Da. Each HAS enzyme is capable of transglycosylation when supplied with UDP-GlcA and UDP-GlcNAc.
Pectinases are a group of enzymes that breaks down pectin, a polysaccharide found in plant cell walls, through hydrolysis, transelimination and deesterification reactions. [1] [2] Commonly referred to as pectic enzymes, they include pectolyase, pectozyme, and polygalacturonase, one of the most studied and widely used [citation needed] commercial pectinases.
α-Amylase is an enzyme (EC 3.2.1.1; systematic name 4-α-D-glucan glucanohydrolase) that hydrolyses α bonds of large, α-linked polysaccharides, such as starch and glycogen, yielding shorter chains thereof, dextrins, and maltose, through the following biochemical process: [2]
Glucanases are enzymes that break down large polysaccharides via hydrolysis. The product of the hydrolysis reaction is called a glucan, a linear polysaccharide made of up to 1200 glucose monomers, held together with glycosidic bonds. [1] Glucans are abundant in the endosperm cell walls of cereals such as barley, rye, sorghum, rice, and wheat. [1]
A lyase is a class of enzyme that catalyzes the breakdown of chemical bonds through an elimination reaction mechanism, rather than a substitution reaction mechanism (hydrolysis and oxidation). Ulvan lyase belongs to the polysaccharide lyase family, a type of enzyme that primarily functions to cleave glycosidic linkages in polysaccharides.
