- Lignin Hydrogenolysis: Phenolic Monomers from Lignin and . . .
Lignification produces guaiacyl G and syringyl S units in a polymer that has no specific sequence; (5,6) p -hydroxyphenyl H units (Figure 2) are typically minor (∼1%)
- Lignin biosynthesis and its integration into metabolism
Lignin is typically described as being composed of p-hydroxyphenyl (H), guaiacyl (G), and syringyl (S) units that derive from the polymerization of the hydroxycinnamyl alcohols, p-coumaryl, coniferyl, and sinapyl alcohol, respectively
- Carbohydrate-aromatic interface and molecular architecture of . . .
Lignin contains guaiacyl (G), syringyl (S), and p -hydroxyphenyl (H) phenolic residues, which are interconnected by different types of covalent linkers such as β-O-4 ether-O-aryl, β-β
- Polyphenol Oxidase Activity on Guaiacyl and Syringyl Lignin . . .
Lignin, the largest renewable source of aromatic carbon in nature, is a heteropolymer composed of phenylpropanoid units that vary in the degree of ortho -methoxylation, namely hydroxyphenyl (H), guaiacyl (G), and syringyl (S) units (Figure 1)
- Types of lignin, properties, and structural characterization . . .
Lignin is made up of three different monolignols (p -coumaryl alcohol, coniferyl alcohol, and sinapyl alcohol) that form specific residues in the lignin structure, namely p -hydroxylphenyl (H), guaiacyl (G), and syringyl (S) units (Fig 4 2)
- Structural units of p-hydroxyphenyl (H), guaiacyl (G), and . . .

- The molecular structure of lignin – GREEN AGROCHEM
In essence, the molecular structure of lignin is a complex, amorphous polymer made up of phenylpropanoid units—guaiacyl (G), syringyl (S), and p-hydroxyphenyl (H)—derived from coniferyl, sinapyl, and p-coumaryl alcohols, respectively
