[Amino acid composition of chicken serum albumin]

Studies have been made on the amino acid composition of electrophoretically homogeneous albumin and its main isoelectrically homogeneous fraction in two strains of hens and their hybrid. Serum albumin of hen and hybrid is characterized by higher total content of Asp and Glu residues as compared with that of the cock (137, 121, and 116 respectively) and lower content of Lys (59 against 66). The acidity of albumin increases in the line cock-hen-hybrid. With respect to its amino acid composition, the maternal serum albumin stands close to the hybrid one.
