Descrizione

Descrizione generale

Biotin is readily available in several foods, like whole grains, nuts, legumes, unpolished rice and egg yolk. The normal gut flora also produces this vitamin.[1]

Applicazioni

Biotin has been used for testing the functionality of the Avidin-displaying phages.[2] The product has also been used for labeling the swine anti-rabbit IgG antibody and peroxidase.[3]

Azioni biochim/fisiol

Biotin acts as an important cofactor for carboxylase enzymes in various metabolic pathways. Biotin favors keratin synthesis and hence is used as a supplement for hair and nail growth. Deficiency of biotin shows several symptoms such as alopecia, conjunctivitis, seborrheic dermatitis, depression, lethargy, hypotonia and seizures.[1]

Biotin also referred to as vitamin H or vitamin B7 is a water-soluble B-vitamin that induces two to three fold increase in guanylate cyclase activity in rat liver, kidney, colon, cerebellum, and heart.[4] It also stimulates the sperm motility and prolongs the survival of cryopreserved human spermatozoa.[5]
