List the branched chain amino acids

isoleucine, leucine, valine

What are proteins held together by

peptide bonds

Complete proteins definition and example

-Contains extra amino acids for protein synthesis

-good digestibility

-usually from animal derived foods

-Ex. chicken

Incomplete proteins definition and example

-1+ limiting amino acids

-usually plant derived foods or processed foods

-Ex. Corn

What are the majority of Amino Acids transported by

sodium dependent transporters

Concentrate

• not as “pure” protein powder

• has more cals (fats and carbs)

• easily available

• cheapest protein powder usually

Isolate

• “purer” protein powder

• increased processing

• more expensive

Hydrolyzed protein

• ultra processed

• smaller peptide units

• easily digestible

• most expensive
