Abstract

The equatorial region of lens fibers of beef and rabbit shoios a higher concentration of the carbohydrate in the albuminoid fraction when calculated either per gram lens or per gram albuminoid.

The ratio of sialic acid to hexosamine and fucose is significantly lower in the polar than in the equatorial region of the cortex.

The content in glycoprotein carbohydrate and hexosamine of the nucleus of the lens in both species is significantly lower than that of either of the two cortical regions.
