used to determine GFR
inulin - homopolymer of fructose
most abundant GAG
chondroitin sulfate
homopolymer of b-d-glucopyranose

Vitamine C is needed for
lysine and proline hydroxylation for collagen formation
tropocollagen
endopeptidases cleave N and C terminal ends on procollagen»_space; tropocollagen
molecules cross link to make collagen fibrils
what part of collagen synthesis occurs in rER
a- chain synthesis
proline + lysine hydroxylation > hydroxyproline + hydroxylysine
what part of collagen synthesis occurs in golgi?
a-chain glycosylation > procollagen
longest known protein
tropocollagen
where is tropocollagen found?
all collagen and reticular fibers except thymus
T/F? Hydroxyproline and hydroxylysine are found in most proteins
false; making them a good estimate of collagen content
desmosine
cross links fibers of tropoelastin
4 lipid types
eicosanoids
triglycerides
phospholipids
steroids
betaine
used by kidney to control water balance
betaine precursor
choline
