Urea 115-119 hemoglobin subunit gamma 1 Homo sapiens 52-66 7243744-2 1981 We have verified that the latter two are the G gamma and A gamma globin chains which have respectively glycine or alanine at position 136. Glycine 103-110 hemoglobin subunit gamma 1 Homo sapiens 45-71 7243744-2 1981 We have verified that the latter two are the G gamma and A gamma globin chains which have respectively glycine or alanine at position 136. Alanine 114-121 hemoglobin subunit gamma 1 Homo sapiens 45-71
