In recent times, wheat has gained more acceptance and utilisation over the traditional staples such as tubers and other cereals in Africa as a consequence of increased demand for dietary enhancement due to urbanisation and increased population in regions where staple was predominantly known to come from maize.

Cowpea (Vigna unguiculata L. Walp) is a crop of significant importance in Africa; it serves as a source of proteins in the tropical and subtropical countries, where Nigeria is ranked the highest in terms of production. It is a source of income for the people of Africa where it is widely cultivated for different purposes. Despite the good attributes of cowpea, one of the major constraints hampering its productivity in Nigeria is drought.

An Introduction to Lipase

Lipases are a group of water-soluble enzymes that catalyze the hydrolysis (and synthesis) of ester bonds in insoluble acylglycerols at lipid-water interfaces. Lipases hydrolyze triacylglycerides into diacylglycerides, monoacylglycerides, free fatty acids and glycerols. Lipase reaction occurs at the interface between the aqueous and the oil phases because of an opposite polarity between the enzyme (hydrophilic) and their substrates (lipophilic).

Genetic Disease Focus: Ataxia–telangiectasia

Ataxia–telangiectasia (AT or A–T), also referred to as ataxia–telangiectasia syndrome or Louis–Bar syndrome is a rare, neurodegenerative, autosomal recessive disease causing severe disability. Ataxia refers to poor coordination and telangiectasia to small dilated blood vessels, both of which are hallmarks of the disease. A–T affects many parts of the body: It impairs certain areas of the brain including the cerebellum, causing difficulty with movement and coordination. It weakens the immune […]
