Abstract

1. 1. Proteins in human milk and Rhesus monkey milk have been compared by FPLC gel filtration and anion exchange chromatography, SDS-Polyacrylamide gel electrophoresis, nitrogen and protein determination. 2. 2. Mature Rhesus milk is higher in protein concentration (15-20 mg/ml) than human milk (8-9 mg/ml). 3. 3. Non-Protein nitrogen is 6-13% in Rhesus milk but 25-30% in human milk. 4. 4. Secretory IgA, lactoferrin, serum albumin, α-lactalbumin and lysozyme are present in Rhesus milk, but at a lower concentration than in human milk. 5. 5. The casein subunit pattern is more complex in Rhesus milk compared to human milk. 6. 6. The ratio of whey proteins to casein is similar in both milks (≈60/40). 7. 7. A protein with a Mrr of 21,600 is a major component in monkey whey but is not found in human milk.
