Porcine Milk Oligosaccharides and Sialic Acid Concentrations Vary Throughout Lactation
BACKGROUND Milk oligosaccharides (OSs) are bioactive components known to influence neonatal development. These compounds have specific physiological functions acting as prebiotics, immune system modulators, and enhancing intestine and brain development. OBJECTIVES The pig is a commonly used model for studying human nutrition, and there is interest in quantifying OS composition of porcine milk...
متن کاملThe role of sialic acid synthases in sialic acid biosynthesis
Introduction The sialic acids comprise a diverse family of nine-carbon keto-sugars, the majority of which are structural derivatives of neuraminic acid (Fig. 1). Neuraminic acid has an amino moiety at the C-5 position, and carboxylate at C-2 which confers negative charge at physiological pH. Whereas unsubstituted neuraminic acid is not known to exist in nature, over 40 substituted variations (c...
متن کاملAssessment of Sialic Acid Distribution in Mouse Epididymis
Previous studies have shown that epididymal epithelium and its secretions are critical for sperm maturation. These secretions contain many glycoconjugates with sialic acid terminal sugar. This terminal sugar by interveining in cellular interactions and masking surface receptors, has an important role in sperm maturation and protection. Moreover lectins have been employed as useful probes to det...
متن کاملSialic Acid in Human Semen
Sialic acid of seminal fluid of eighty two human subjects has been studied in relation to infertility. Normozoospermic group had highest sialic acid content (94 mgm/100 mt of the fluid) and was sign ificantly different from other groups. The lowest sialic acid level was observed: n necrozoosperm ic group (54 mgm/1 00 mt of the fluid). Azoospermic (62 mgm/100 ml) and vasectomised group (73 mgm/1...
متن کاملConcentration and distribution of sialic acid in human milk and infant formulas.
BACKGROUND In animal studies, sialic acid supplementation is associated with increases of gangliosides in the brain and improved learning ability. Only limited data are available on the sialic acid content of human milk and infant formulas. OBJECTIVE We compared the concentrations of oligosaccharide-bound, protein-bound, and free sialic acid in milk from mothers of full-term and preterm infan...
