Chem Flashcards
what is oxydation
loss of hydrogen + gain of oxy
What is a reduction reaction
gain of hydrogen + loss of oxidation
What is a carboxylation run
where a carboxyl group is added or displaces a hydrogen atom
what is a decarboxylation run
Carboxyl group is removed from organic compound and hydrogen is added
What is the enzyme that adds and removes phosphate
Phosphorylase- adds inorganic phosphate
Phosphatase- removes phosphate group from its substate
What is non competative inhibition
Binds enzyme at a site other than the enzymes active site and is irreversible
What is competitive inhibition
Binds to the same active site as the normal enzyme and is reversible
What is allosteric regulation
Enzymes activity is regulated by binding an effector molecule at the enzymes allosteric site
kcal off carbs, pro, fats, alc
carbs- 4
pro-4
fat-9
alc-7
What is a peptide bond
covalent bond (usually occurs bw amino acids)
What is a hydrogen bond
dipole-dipole force (bw DNA/RNA)
What is an est4er bond
chemical covalent bond w glycerol and fatty acids
hWhat is a phosphodiester bond
chem bond bw 2 nucleotides
