대두발효식품의 cerebroside 조성 및 생리활성

Cerebrosides were isolated from soybean, deunjang and chungkukjang and their constituents were investigated. The principal fatty acid of soybean cerebroside was 2-hydroxy-palmitic acid but chungkukjang cerebroside consisted palmitic acid, elaidic acid(trans 18:1), oleic acid and stearic acid. The only sugar in cerebrosides was glucose. TLC analysis of cerebroside hydrolysate elucidated soybean and chungkukjang had same sphingold bases, mainly dihydroxy bases, trans-4, trans-sphingadienine. But, alkali stable glycolipid fractions of chungkukjang and deunjang had $2{\sim}3$ different primary amines.
