NTR 109 Lecture Notes - Lecture 6: Neural Tube Defect, Vitamin D Deficiency, Beta-Carotene
Document Summary
Vitamin c & b vitamins (vitamin b6, vitamin b12, thiamin, niacin (5 hr energy), folate, riboflavin, biotin, pantothenic acid) Takes less time for deficiency to develop due to limited stores. Highly toxic especially vitamin d & a. Red blood cells (a single cell lasts 3 months: pregnancy fetal development. Neural tube development 1st few weeks of pregnancy. Anemia (megaloblastic) large, immature red blood cells. Neural tube defects a defect in the formation of the neural tube (spinal column protects spinal cord & skull protects brain) during early fetal development. Neural tube develops in 1st month of gestation. Defect occurs when spinal column or skull don"t form properly. Spina bifida failure of neural tube to close. Spinal cord bulges through the back: results in paralysis. All women of childbearing age 400 ug/day (neural tube forms before most women know they are pregnant) (no need to memorize the no. ) Co-enzymes are needed for the enzymes to do their job.
