NUTRITION Flashcards
AMINO ACIDS
Organic building blocks of proteins containing both a carboxyl and an amino group.
PEPTIDE BOND
A chemical bond that connects two amino acids.
SUBSTRATES
Intermediate forms of nutrients used in metabolic reactions to create adenosine triphosphate.
PROTEIN TURNOVER
A process in which the body breaks down existing proteins and recycles the component amino acids for incorporation into new proteins or other nitrogen-containing compounds.
complete protein
A protein source that provides all essential amino acids.
HBV PROTEINS
foods containing all 9 essential amino acids
LBV proteins
foods missing 1 or more essential amino acids
ENTEROCYTE
intestinal cells that absorb nutrients
GLUCONEOGENESIS
The formation of glucose from noncarbohydrate sources (proteins and fats).
Anaerobic
PROCESSES RELATING TO THE ABSENCE OF OXYGEN
AEROBIC
PROCESSES RELATING TO OXYGEN
Thermic effect of food (TEF)
The energy required to digest, absorb, and process nutrients that are consumed.
SIMPLE SUGARS
Include the monosaccharides and disaccharides; easily absorbed into the bloodstream.
Monosaccharides
Simplest form of carbohydrate; single sugar molecules (e.g., glucose).
Disaccharides
Two monosaccharides joined together to form a simple sugar. The three disaccharides of nutritional importance include lactose, sucrose, and maltose.
