Document Summary

Nsc 170c1 fall 2016 exam 3 study guide. Differentiate between fat soluble and water soluble vitamins: fat soluble vitamins. Stored by body because cannot be dissolve in water. In fats, oils, and fatty portions of food: water soluble vitamins. Thiamin, riboflavin, niacin, vitamin b-6, pantothenic acid, folate, biotin, and vitamin b-12. Dissolve in water components of food and body. Small molecule that helps an enzyme function. Are made from an inactive compound + b vitamin. Describe the function of antioxidant vitamins: vitamins c, e, and beta-carotene, protect cells by giving up electrons to free radicals. The f(cid:396)ee (cid:396)adi(cid:272)als (cid:449)o(cid:374)"t remove electrons from more stable molecules, such as proteins, fatty acids, and dna.

By sacrificing electrons, antioxidants protect molecules such as polyunsaturated fatty acids.
