As part of a study of the 'whey' proteins of various mammals, a comparison is made of the alpha-lactalbumins and lysozymes of the kangaroo and horse. In the milk of the red kangaroo (Megaleia rufa) there is only one alpha-lactalbumin and it occurs throughout lactation, but no lysozyme has been detected. There are two alpha-lactalbumins in the milk of the grey kangaroo (Macropus giganteus), one, designated alpha-lactalbumin Zone B, is present throughout lactation; the second, designated alpha-lactalbumin Zone A, is present only in late lactation. One lysozyme is also present. The milk of the horse (Equus caballus) contains one alpha-lactalbumin and at least one lysozyme. Partial amino acid sequences are proposed from sequence determination and from analyses of tryptic peptides compared with the known sequences of other alpha-lactalbumins and lysozymes.
作为对各种哺乳动物“乳清”蛋白研究的一部分，对袋鼠和马的α-乳白蛋白和溶菌酶进行了比较。在红袋鼠（大赤袋鼠）的乳汁中，只有一种α-乳白蛋白，且在整个哺乳期都存在，但未检测到溶菌酶。灰袋鼠（大袋鼠）的乳汁中有两种α-乳白蛋白，一种称为α-乳白蛋白B区，在整个哺乳期都存在；另一种称为α-乳白蛋白A区，仅在哺乳期后期存在。同时也存在一种溶菌酶。马（家马）的乳汁含有一种α-乳白蛋白和至少一种溶菌酶。通过序列测定以及与其他α-乳白蛋白和溶菌酶已知序列比较胰蛋白酶肽段分析，提出了部分氨基酸序列。
