The Chemical Reactions and Pathways Involving Carbohydrates Any of a Group of Organic Compounds Based of the General Formula Cx(h2o)y. Includes the Formation of Carbohydrate Derivatives by the Addition of a Carbohydrate Residue to Another Molecule.
A Process That Results in the Assembly Arrangement of Constituent Parts or Disassembly of the Cell Wall the Rigid or Semi Rigid Envelope Lying Outside the Cell Membrane of Plant Fungal and Most Prokaryotic Cells Maintaining Their Shape and Protecting Them From Osmotic Lysis.
The Space External to the Outermost Structure of a Cell. For Cells Without External Protective or External Encapsulating Structures This Refers to Space Outside of the Plasma Membrane. This Term Covers the Host Cell Environment Outside an Intracellular Parasite.
Catalysis of the Cleavage of C C C O C N and Other Bonds by Other Means Than by Hydrolysis or Oxidation or Conversely Adding a Group to a Double Bond. They Differ From Other Enzymes in That Two Substrates Are Involved in One Reaction Direction But Only One in the Other Direction. When Acting On the Single Substrate a Molecule Is Eliminated and This Generates Either a New Double Bond or a New Ring.
Catalysis of the Reaction: a Pectin = an Oligosaccharide with 4 Deoxy 6 O Methyl Alpha D Galact 4 Enuronate End + a Pectin. This Reaction Is the Eliminative Cleavage of (1 >4) Alpha D Galacturonan Methyl Ester to Give Oligosaccharides with 4 Deoxy 6 O Methyl Alpha D Galact 4 Enuronosyl Groups At Their Nonreducing Ends.
