Cards in this deck (16)
- 1What is protein?Polymer of amino acids
- 2Draw the basic structure of an amino acid
- 3What bond occurs in a condensation reaction?Peptide bond
- 4Approximately how many amino acids are considered important in human nutrition?20
- 5What are the three categories of amino acids?Indispensable
dispensable
conditionally indispensable - 6Describe indispensable AA'spreviously called essential,
eight in total,
cannot be synthesized,
must be supplied in the diet - 7What are the eight Indispensable AA's?isoleucine (Ile)
leucine (Leu)
lysine (Lys)
methionine (met)
phenylalanine (Phe)
threonine (Thr)
tryptophan (Trp)
valine (val) - 8Describe Dispensable AA'spreviously called non-essential
3 in total
can be synthesized in body in sufficient quantity
from c-skeleton and transamination - 9What are the dispensable AA'salanine (ala)
aspartic acid (asp)
glutamic acid (Glu) - 10Describe conditionally indispensable AA'spreviously called conditionally essential
nine
synthesized in the body
needed under certain conditions includ. immaturity, metabolic disorders, stress, prolonged TPN. - 11What are the conditionally indispensable AA's?arginine (Arg)
asparagine (Asn)
cysteine (Cys)
glutamine (Gln)
glycine (Gly)
Histidine (His)
proline (pro)
serine (ser)
tyrosine (Tyr) - 12What is Transaminationprocess of transferring amino group from one carbon skeleton to another.
makes dispensable AA from another AA
mostly occurs in the liver - 13What is De-amination?Process of removing amino groups from AA
Amino group changed into urea for excretion
carbon skeleton used for energy - 14What is Nitrogen balance?Nitrogen intake - nitrogen losses
- 15Give an example of positive N balanceGrowth
- 16Rate of synthesis/ breakdown of body protein = ?intensity of N metabolism
