Exam 2 Flashcards
2 types of cretinism
Neurological - deaf and mental retardation
Myxedematous- growth is retarded
Iodine deficiency
Cretinism
Protein benefits of breast milk
1) High cystine, low methionine (baby doesn’t have cystathione synthase)
2) low phenylalanine and tyrosine (no tyrosine amino transferase or parahydroxyphenyl pyruvate oxidase)
3) high taurine, need for bile salts (babies can’t make taurine)
Lipid perks of breastmilk
Essential FAs (Linolenic and linoleic) Cholesterol Omega 3's Lipases (bile salt stimulated lipase) Carnitine
Carnitine importance
Lysine+methionine
Premature can’t make
Transfer long chains across mito membrane
Lipases in milk
Bile salt stimulated
Helps with fat digestion
Cholesterol importance in milk
Helps form myelin
Develop cholesterol degrading enzymes
Omega 3 importance in milk
DHA and EPA
Brain and retina development
Lactose importance?
Helps organic acids producing organisms
Acid helps avoid bad bacteria growth and absorb minerals
Carbs in breastmilk
Lactose
Amylase
Oligosaccharides= bind toxins> trapping receptors
Breastmilk minerals
Iron and zinc
High bioavailability because lactoferrin
High in colostrum
Fights E. coli and enteroviruses
IgA
5
1 (G) from mother plasma
4 from mammary tissue
Immunoglobulins
Bonds iron
Blocks bacteria from getting iron
Anti fungal
Fights staphylococci and E. coli
Lactoferrin
Helps lactobacillus grow
fight enteropathogenic bacteria
Oligosaccharide with nitrogen
Bifidus factor
