The Role of Carbohydrate in Maintaining Extensin in an Extended Conformation [PDF]

Plant Physiology, 1986
Monomers of the plant cell wall glycoprotein extensin are secreted into the wall where they become cross-linked to each other to form a rigid matrix. Expression of the extensin matrix is correlated with the inhibition of further cell elongation during normal development, with increased resistance to virulent pathogens and with other physiological ...

Silyl-protective groups influencing the reactivity and selectivity in glycosylations

Beilstein Journal of Organic Chemistry, 2017
Silyl groups such as TBDPS, TBDMS, TIPS or TMS are well-known and widely used alcohol protective groups in organic chemistry. Cyclic silylene protective groups are also becoming increasingly popular. In carbohydrate chemistry silyl protective groups have
