<unk>  (plasma), Human.<unk> s <unk>  are a family of proteins with diverse functions. They are carrier proteins that bind<unk> . Assessment of<unk>  is used to determine visceral protein mass in health-related nutritional studies.<unk>  and<unk> c acid play crucial roles in the modulation of gene expression and overall development of an embryo. However, deficit or excess of either one of these substances can cause early embryo mortality or developmental malformations. Regulation of transport and metabolism of<unk>  necessary for a successful pregnancy is accomplished via<unk> .<unk> s have been identified within the uterus, embryo, and extraembryonic tissue of the bovine, ovine, and porcine, clearly indicating that<unk>  plays a role in proper<unk>  exposure to the embryo and successful transport at the maternal-fetal interface. Further research is necessary to determine the exact effects of poor<unk>  expression on pregnancy and threshold levels for said expression.
