NFS382H1 Lecture Notes - Lecture 9: Heme, Bacterial Growth, Lipid Peroxidation
Document Summary
Human body contains ~2 to 4 g of iron. Up to 10% is found in myoglobin. Rest is in blood or in storage. Iron is found in food and the body as ferric iron (fe3+) or ferrous iron (fe2+: makes a difference in absorption. Iron is one of those nutrients that you always want bound to something can be harmful when not bound (lipid oxidation, bacterial growth) Almost always bound in the body: redox potential, bacterial growth, rda. Iron is not going to help babies meet their iron requirements. Babies rely on their own stores of iron when they are born i(cid:374)flue(cid:374)(cid:272)ed (cid:271)y (cid:373)other"s iro(cid:374) duri(cid:374)g pregnancy. There is a big bulk transfer in the third trimester. Iron status in babies is related to their size larger babies have more iron (have enough iron stores to last for 6 months) Small babies have very little iron stores will not last size months.
