It was concluded that a component of the egg-white was sequestering biotin [8] which Snell verified in vitro using a yeast assay. [9] Snell later isolated the component of egg white responsible for biotin binding, and, in collaboration with Paul György , confirmed that the isolated egg protein was the cause of biotin deficiency or “egg white ...
Eggs: Eggs are an excellent source of biotin, particularly the yolk. One medium egg contains 10 mcg (33% DV). Get a healthy dose of biotin with our 3-Ingredient Bell Pepper & Cheese Egg Cups.
One whole egg, cooked, provides 10mcg of biotin, which is about 33% of your daily value. So if you eat a three-egg omelet or scramble, consider your biotin needs met for the day.
Because egg-derived avidin binds strongly to biotin with a dissociation constant K d ≈ 10 −15 M, [34] biotinylated compounds of interest can be isolated from a sample by exploiting this highly stable interaction. First, the chemically modified biotin reagents are bound to the targeted compounds in a solution via a process called biotinylation.
Deficiency is rare [2] in locations where egg-white enriched or ketogenic diets are common. [29] Pregnancy, however, alters biomarkers of biotin [30] and despite a regular biotin intake, approximately half of the pregnant women in the U.S. are marginally biotin deficient. [14]
The U.S. Food and Drug Administration (FDA) now classifies eggs as a “healthy, nutrient-dense" food, according to a new proposed rule. Registered dietitians react to the change.
In August 2010, the FDA ordered the recall of 380 million eggs because of possible Salmonella contamination. [12] Cooked eggs are a good source of biotin. However, daily consumption of raw egg whites for several months may result in biotin deficiency, due to their avidin content, as the avidin tightly binds biotin and prevents its absorption. [13]
