galactose

 [gah-lak´tōs]
a monosaccharide sugar of the aldose group, derived from lactose. d-galactose is found in lactose, in cerebrosides of the brain, in the sugar beet, and in many gums and seaweeds; l-galactose is found in flaxseed mucilage.
galactose tolerance test a laboratory test done to determine the liver's ability to convert the sugar galactose into glycogen. Two methods may be used. The oral method requires about 5 hours to complete, and the intravenous method, which is more accurate, requires about 2 hours. With the oral method, elimination of more than 3 g of galactose in the urine during a 5-hour period indicates liver damage. With the intravenous method, all galactose should have been eliminated from the blood 45 minutes after its injection.

The richest source of [alpha] - galactosides are the seeds of legumes, among which the lupine seeds contain up to 7-15% (Villaluenga et al.
The applied galactosides originate from extracts of the residue after the debitering process of bitter lupin seeds galactosides (Gulewicz et al.
Potentially increased intestinal absorption of nutrients as a result of single in ovo injection of [alpha] - galactosides can be the basis for achieving better production results and finally positive economic effects.
Effects of a single injection of [alpha] - galactosides on the 12th day of incubation are shown in Table 2.
It is difficult to compare the result from this study with literature data, because research on the effects of in ovo injection of [alpha] - galactosides has not been made so far.
To some extent, this fact may explain the higher rate of resorption of the yolk sac observed by in previous studies in experimental broiler chickens group injected at the 12th day of embryogenesis with [alpha] - galactosides (Brudnicki et al.
On the basis of this paper it can be assumed that the described mechanism implies the morphological characteristics of the small intestine in broiler chickens injected in ovo with [alpha] - galactosides observed on the day of hatching in the present study.
In our study, it was found that in ovo injection of [alpha] - galactosides on the 12th day of breeding significantly affects the increase in the villi surface area in all segments of the intestine up to 4th days and duodenum up to 7 th days, which could potentially lead to an increased growth and productivity of birds.
Galactosyl cyclitols, raffinose, or stachyose were not detected in leaf tissue disks or in seed coat cup exudates indicating the absence of galactosyl cyclitols in leaves and suggesting that free cyclitols are transported from maternal tissues to soybean embryos where they are converted to their respective galactosides.
Although, the mechanism whereby the injection in ovo of galactosides accelerates the resorption of the content of the yolk sac and the related implications require further research.
