chapter seven part 4 amino acids

pathways for amino acids their are four

1. convert to pyruvate=glucose 2. convert to acetyl coa=energy/body fat 3. enter TCA cycle directly as compounds 4. generate glucose

amino acids need to ____ before entering metabolic pathway . which means they need to lose their ___.

deamination nitrogen

when energy excees bodys need all 3 stores as ___-

fats

glucogenic and ketogenic amino acid metabolism step one

glucogenic amino acids are converted to pyruvate and then transformed into glucose through gluconeogenesis

protein unlike fat is a good source of ____ when carbs are not available

glucose

to make proteins body needs amino acids it can use glucose and ____ to make _____ amino acids when nitrogen is available

glycerol nonessential

ketogeic verses glucogenic amino acids both ketogenic and glucogenic amino acids

isoleucine trypotophan phenylalanine tyrosine

glucogenic and ketogenic amino acid metabolism step two

ketogenic amino acids are converted to acetyl coa which can either be transformed into fatty acids and stored as a triglyceride in adiposes tissue or enter tca cycle

ketogeniv verses glucogenic amino acids ketogenic amino acids are

leucine lysine

when amino acids deaminations this provides the nitrogen needed to make ________ amino acids and other nitrogen containing compounds .

nonessential

how does proteins provide energy ? amino acids primary ! use most important function is building ____ if the amino acid is not used to build protein the amine group must be removed through _______/ excess can be used for energy production converted to ____ or stored as ____ used in a limited extent for _____ in diets low in Kcal and or carbohydrates.

protein deamination glucose fat energy

ACETLY COA CANNOT BE USED TO MAKE

GLUCOSE

to make glucose body can use ___ ____ and only 5% of fat to glucose (____) fatty acids can not make glucose

amino acids carbbs glycerols

Amino acids to glucose Glucogenic amino acids major source of ___ glucose when diet is lacking _____ can come from food can come from break down of ____

blood carbs muscles

amino acids can produce___ produce___ convert ___ acids and can be stored as _____ must be _____ to be used for energy once deaminated can be transformed into _____ _____ _____ glucogenic amino acids can convert to _____

energy glucose fatty fat deaminated pyruvate acetyl coa tca cycle glucose

step 3 glucogenic and ketogenic amino acid metabolism step 3

some amino acids can enter the TCA cycle directly

glucogenic amino acids

the forteen other amino acids
