Studies on Rainbow Trout Egg (Salmo gairdnerii irideus) : II. Carbohydrate in the Egg Protein

虹鱒卵の生化学的研究 : II 卵蛋白質中の炭水化物について
Nakagawa, Heisuke
(1) The component I which is a lipoprotein isolated from immature egg of rainbow trout contained hexose, hexosamine, and sialic acid as the carbohydrate constituent, Mannose predominated over galactose and glucose. The carbohydrate content of the component 1 was lower than that of lipovitellin of hen's egg.

(2) The component I1 contained both hexose and pentose. It is suggested that the substance is a kind of glycoprotein similar to livetin of hen's egg yolk.

(3) The method for simultaneous determination of hexose and pentose was discussed.
