Zhao et al.34reported that algal bioactive metabolites showed hypoglycaemic benefits through inhibition of carbohydrate digestive enzymes (either α‐amylase or α‐glucosidase), the inhibition of postprandial hyperglycaemia, the activation of Akt and AMP‐activated protein kinase signalling cascades, the increasing/improving of insulin secretion, the improving insulin sensitivity, delaying glucose absorption and the inhibition of protein tyrosine phosphatase 1B signalling pathway in a dose‐dependent manner. The gene discussed is AKT1; the disease is Hyperglycemia.
