NUTR 120 Lecture Notes - Lecture 13: Sickle-Cell Disease, Lignan, Lignin
Document Summary
Lignan is not a fibre a plant estrogenic substance. Proteins: structure/function relationship: the amino acid sequence of a protein determines its final 3-d shape, a p(cid:396)otei(cid:374)(cid:859)s shape is (cid:272)(cid:396)iti(cid:272)al to its fu(cid:374)(cid:272)tio(cid:374), e. g. Lose its function: altering amino acid sequence can change protein function dramatically, even 1 aa change results in change of shape, and therefore function, in hemoglobin can lead so sickle cell anemia. Hemoglobin is made of 4 subunits, and each of them have a heme structure (fe) and it is where oxygen is bound. Mostly from meats, dairy products, cereal products (grains) Most vegetables are not high in protein but broccoli, cauliflower, cabbages do have protein.

There are things protein can only do for our body. Growth and repair of tissues muscle protein e. g. collagen (mechanical support for skin and bone)
