An &#x3b1;-selective glycosylation process of a glycosylation reaction between a sugar structure of hexose or an aldose having a chain with six or more carbon atoms in the molecule, which is a monosaccharide or a reducing end of an oligosaccharide with two or more monosaccharide residues connected by glycosidic linkages (an oligosaccharide with two monosaccharide residues is disaccharide) (also referred to as 'a disaccharide to an oligosaccharide') or a sugar chain and alcoholic hydroxyl group or thiol group, to obtain a sugar structure glycoside containing &#x3b1;-glycoside at a high ratio, under the ring-shaped formation of a protective group in a silyl acetal structure over hydroxyl groups at positions 4 and 6 in the sugar structure. By the process, highly selective &#x3b1;-glycosylation of sugar structure can be progressed in a simple and efficient manner.

Carboxymethylgalactose derivatives

Novel glycolipid derivatives of Formula (I): ##STR1## wherein R is a long chain alkyl, or their salts are disclosed. These compounds act as a ligand for selectin family and exhibit a remarkable inhibitory effect on the binding of selectin family to its native ligand sialyl Lewis.sup.x.

Glycolipid derivatives acting as ligands for selectins

This invention provides a lead-acid battery plate and its manufacturing method. In a lead-acid battery plate making use of an expanded metal comprising copper or copper alloy electroplated with lead or lead alloy for its grid; this invention is characterized by that a protector is provided on a side of the grid. And in a manufacturing method for a lead acid battery plate in which the expanded metal comprising copper or copper alloy electroplated with lead or lead alloy is used for its grid, and a plate lug comprising lead or lead alloy is connected by casting to an upper part of the grid; this invention is characterized by that the plate lug is first connected by casting to the upper part of the copper expanded metal, and lead or lead alloy is then electroplated on the copper expanded metal to which the plate lug is connected.
