The insertion of bioactive peptides at the C-terminal end of an 11S globulin changes the structural stability and improves the antihypertensive activity

BACKGROUND: The 11S globulin from amaranth is the most abundant storage protein in mature seeds and is well recognized for its nutritional value. We used this globulin to engineer a new protein by adding a four valinetyrosine antihypertensive peptide at its C-terminal end to improve its functionality. Th...

Role of the consumption of fucoidans and beta-glucans on human health: an update of the literature

Rev. chil. nutr; 46 (6), 2019
ABSTRACT Bioactive compounds are substances present in low doses in foods mostly from the plant kingdom. Their consumption can influence physiological or cellular processes and has a beneficial effect on health.
