Folate activity in human milk.
The available data on the folic acid content of human milk (Macy, 1949; Collins, Harper, Schreiber & Elvehjem, 1951; see also e.g. Macy & Kelly, 1961) are based on determinations made at a time when the biochemical role of folic acid, and also the nature and properties of the biologically active cofactors of the vitamin, were imperfectly understood. I t is now known that folic acid exists in a ...
متن کاملFolate determination in human milk.
extraction of folates in the absence of a reducing agent, such as ascorbate, is known to be unsuitable for biological samples that contain principaLly reduced tbrms of tblate. When the method by Allfrey ct al. (2) is used for biological samples, the values are generally lower than those obtained by other methods, such as microbiological assay {4). The use of a reducing agent during the extracti...
متن کاملHuman milk folate and folate status in lactating mothers and their infants.
Plasma and red blood cell folate levels of healthy, well-nourished lactating mothers were measured. Folate levels in their breast-fed infants were significantly higher than in the mothers. No abnormal hematological findings were observed in either mothers or infants. Folate levels in breast milk and in the infants' plasma were significantly correlated. The mean breast-milk folate level was 141....
متن کاملFolate contents in human milk and casein-based and soya-based formulas, and folate status in Korean infants.
We assessed folate nutritional status from birth to 12 months in fifty-one infants who were fed human milk (HM; n 20), casein-based formula (CBF; n 12) or soya-based formula (SBF; n 19). Folate contents in ninety-five HM samples obtained from twenty mothers for the first 6-month period and twelve CBF and nineteen SBF samples were measured by bioassay after trienzyme extraction. Folate intake wa...
متن کاملVitamin B12 and folate activity in normal human platelets.
Preparation of platelets. Venous blood from normal male and female subjects, ages 20-40, was mixed (9: 1) with 1 per cent EDTA in 0.7 per cent saline in siliconized tubes and centrifuged at 2500 rpm in a PR-2 centrifuge for 3 minutes to obtain platelet-rich plasma (PRP). Subsequent centrifugations were at 3000 rpm and 4 C. for 30 minutes. A platelet button was obtained by centrifuging the PRP, ...
