A sulfated sugar nucleotide has been isolated from quail egg white, and accounts for nearly 80% of the total sugar nucleotides found in the egg white. Evidence is presented that this nucleotide is uridine diphosphate N-acetylgalactosamine 6-sulfate, an isomer of the 4-sulfated derivative of uridine diphosphate N-acetylgalactosamine previously found in chicken egg white. Further studies on the distribution of sulfated sugar nucleotides in egg white of various birds (chicken, quail, pheasant, peafowl, turkey, goose, and duck) demonstrate that each species has a characteristic composition, differing from one another regarding the relative amounts of 4-sulfated, 6-sulfated, and 4,6-bissulfated derivatives of uridine diphosphate N-acetylgalactosamine.
一种硫酸化糖核苷酸已从鹌鹑蛋清中分离出来，占蛋清中发现的总糖核苷酸的近80%。有证据表明，这种核苷酸是尿苷二磷酸N-乙酰半乳糖胺6-硫酸盐，是先前在鸡蛋白中发现的尿苷二磷酸N-乙酰半乳糖胺4-硫酸化衍生物的异构体。对各种鸟类（鸡、鹌鹑、雉鸡、孔雀、火鸡、鹅和鸭）蛋清中硫酸化糖核苷酸分布的进一步研究表明，每个物种都有其独特的组成，在尿苷二磷酸N-乙酰半乳糖胺的4-硫酸化、6-硫酸化和4,6-双硫酸化衍生物的相对含量上彼此不同。
