Amino acid carrying ammonia from muscle to liver
Under conditions of starvation, the glucose alanine cycle is of special metabolic significance (Fig. 9.30). Alanine is quantitatively the most impoant amino acid taken up by the liver from peripheral tissues, paicularly from skeletal muscle. It forms a major paicipant in inter-organ transpo of nitrogen (Figs 14.4 and 14.5).Ref: DM Vasudevan - Textbook of Biochemistry, 6th edition, page no: 187
