The composition of milk deposits in an ultra-high-temperature plant

Autor: R. L. J. Lyster

Publikováno v: Journal of Dairy Research. 32:203-208

SummaryMilk deposits from an ultra-high-temperature (UHT) plant were analysed for protein, fat and minerals. The physical appearance and composition of the deposits was found to vary with modifications of the plant. For each particular arrangement of

Changes in the quantity and composition of mammary gland secretion in the dry period between lactations: I. The beginning of the dry period

Autor: F. H. Dodd, R. L. J. Lyster, A. Smith, J. V. Wheelock

Publikováno v: Journal of Dairy Research. 34:1-12

SummaryThe changes in the yield and composition of the mammary gland secretion in the first 16 days of the dry period have been investigated in 6 cows. The quantity of secretion, lactose, potassium, casein, α-lactalbumin, β-lactoglobulin and fat pr

The denaturation of α-lactalbumin and β-lactoglobulin in heated milk

Autor: R. L. J. Lyster

Publikováno v: Journal of Dairy Research. 37:233-243

SummaryThe rates of denaturation by heat of α-lactalbumin and β-lactoglobulin in skim-milk were measured by an immunodiffusion method over a wide range of temperatures. Both reactions showed an unusual temperature dependence.The denaturation of α-

Occurrence of milk proteins in the urine of cows during an extended milking interval

Autor: J. V. Wheelock, R. L. J. Lyster

Publikováno v: Journal of Dairy Research. 34:27-30

SummaryImmunological methods have been used to test samples of urine from 5 cows for the presence of milk proteins. None could be detected when the cows were milked twice daily at the usual intervals, but during an extended milking interval α-lactal

The reactivation of milk alkaline phosphatase after heat treatment

Autor: R. Aschaffenburg, R. L. J. Lyster

Publikováno v: Journal of Dairy Research. 29:21-35

SummaryA simple system was developed, consisting of a solution of β-glycerophosphate, β-lactoglobulin and magnesium ions, in which alkaline phosphatase isolated from milk became strongly reactivated following heat treatment for 45 sec in boiling wa

The determination of the individual equilibrium constants of the four intermediate reactions between oxygen and sheep haemoglobin

Autor: A. B. Otis, R. L. J. Lyster, Francis John Worsley Roughton

Publikováno v: Proceedings of the Royal Society of London. Series B - Biological Sciences. 144:29-54

It is now generally accepted that the equilibrium between oxygen (or carbon monoxide) and mammalian haemoglobin is expressible in terms of four intermediate reactions Hb 4 + O 2 ⇌ Hb 4 O 2 (equilibrium constant K 1 ), Hb 4 O 2 + O 2 ⇌ Hb 4 O 4 (
