BIOCHEMISTRY Lecture Notes - Lecture 1: Gut Flora, Riboflavin, Angular Cheilitis

10. How would a deficiency in niacin, thiamine, riboflavin, or biotin influence metabolism?

1. An average man is requires about 2.00 mg of fiboflavin (vitaminB2) per day. Cheese contains 5.5μg of riboflavin per gram ofcheese. How many pounds of cheese would a man have to eat per dayif this is his only source of riboflavin?

Nutrition

An athlete is assessed for riboflavin status using erthyrocyte glutathionine reductase activity coefficient. The cut-off is 1.2, and this athlete's result was 1.3. What does this result indicate for the athletes riboflavin status (i.e. deficient, normal, toxic)? How does the enzyme coefficent measure riboflaviin status?
