title: [Participation of glutamate and alanine in amino acid biosynthesis, in lipogenesis, and in gluconeogenesis in the brain].
abstract: The participation of glutamate and alanine in lipogenesis and gluconeogenesis of brain was investigated. 5(14)C glutamate was injected intracisternally in an amount of 5 mcCu/l g tissue and 3(14)C-alanine was injected subcutaneously 30 mcCu/100 g body weight. Labels from glutamate and alanine were recovered in different lipid franctions -- in phospholipids, glycerides, free fatty acids and cholesterol, as well as in glucose and glycogen. An intensive incorporation of label from 5(14)C glutamate into various amino acids--aspartic acid, glutamine, serine, glycine and alanine--was demonstrated. The data presented indicate the participation of amino acids in lipogenesis and gluconeogenesis of brain.
