Nutritional Biochemistry and Clinical Dietetics Flashcards
healthy weight loss
0.5 - 1 lb per week
5 g salt
2300 mg sodium
major site of amino acid degradation
liver
Aminotransferases
catalyze the transfer of an α-amino group from an α-amino acid to an α-ketoacid
Anti-Diuretic Hormone
Causes kidneys to conserve fluid
transaminases,
generally funnel α-amino groups from a variety of amino acids to α-keto-glutarate for conversion into NH4+.
Second stage of carbohydrate metabolism
Oxidative decarboxylation
Arachidonic acid- omega 6
Precursor of prostaglandin thromboxane A2 which causes platelet aggregation, clott formation, and vasocontriction
Protects folate from oxidation
Vitamin C
Two amino acids with no metabolic precursors
Lysine and threonine
Symptoms of ariboflavinosis
cheilosis, glossitis, photophobia
Erythrocyte hemolysis is a sign of
vitamin E deficiency
Nutrient that interferes with Vitamin A utilization
Zinc
Aldosterone
kidney hormone that causes sodium reabsorption
normal blood osmolality
300mOsm
A glycogen storage disease (GSD)
results from the absence of enzymes that ultimately convert glycogen compounds to glucose. Enzyme deficiency results in glycogen accumulation in tissues.
Principal measured index of renal failure
urea
High calcium content of diet
800 mg
Energy allowance for severely malnourished infant
80-140 kcal/kg
intermediate acting insulin
NPH- peak of action 6-10 hrs
Protein allowance for severely malnourished children
3-4 g Pro/kg BW
Protein requirement of Gout patients
1 g Pro/Kg BW
Respiratory quotient
= moles of CO2 expired/ moles of O2 consumed
vitamins whose reqts are based on an individual’s energy intakeq
B1 and B2
