proteins Flashcards
protos
primary, first
contains
carbon, hydrogen, oxygen, nitrogen
albumins
soluble in water, coagulated by heat
globulins`
insoluble in water, solublle in dilute salt solution, coagulated by heat
glutelin
insoluble in neutral solvents, soluble in weak acids and alkalis
compound proteins
simple proteins + non protein substance (prosthetic group)
promalins
insoluble in absolute alcohol
albuminoids
insoluble in neutral solvents, dilute in acids and alkalis
histones and protamines
basic polypeptides; soluble in water but not coagulated with heat; found in cells’ nucleis
nucleoproteins
proteins + nucleic acids
mucoproteins & glycoproteins
protein + polysaccharide
lipoprotein
protein + lipid
phosphoproteins
protein + phosphoric acid
chomoproteins
protein + non protein pigments found in flavorproteins, hemoglobin, cytochromes
metalloproteins
proteins + metals
derived proteins
products formed in the various stages of hydrolysis of a protein molecule
peptide linkage
chain of amino acids
polypetides
long chain of amino acids linked by peptide bond
essential amino acids
cannot be synthesized by the body and is necessary in diet
non essential amino acids
manufactured by the body
complete proteins
contain all essential amino acids
incomplete proteins
defficient in one or more essential amino acids
enzymes in pancreas
trypsin
chymotrypsin
carboxypeptidase
what enzyme in infants converts casein into curd?
rennin
trypsin
converts proteins into polypeptides
chymotrypsin
coagulates milk
carboxypeptidase
polypeptides to simpler peptides
proteins in the intestine
aminopeptidase
dipeptidase
aminopeptidase
polypeptides to peptides and amino acids
marasmus
severe deprivation of food over a long period of time
dipeptidase
dipeptidase to amino acids
