EXAMPLES OF SIMPLE PROTEINS & CONJUGATED PROTEINS Flashcards
NUCLEO / GLYCO:
Viruses (self-replicating, infectious complex)
NUCLEO
NUCLEO / GLYCO:
Simple proteins like globulins and albumins
GLYCO
LIPO / METALLO:
high-density lipoprotein (HDL) – lipid carrier
LIPO
Mixtures of fragments of original proteins varying in composition and size
Secondary Protein derivatives
Examples:
-Serum albumin (blood)
-Lactalbumin (milk)
-Ovalbumin (eggwhite)
ALBUMINS
NUCLEO / GLYCO:
Chromatin
NUCLEO
PHOSPHO / CHROMO:
Casein (milk)
PHOSPHOPROTEINS
LIPO / METALLO:
iron–ferritin (storage complex for iron)
METALLO
Exhibit certain common properties such as solubility in water and non -coagulability by heat
Secondary Protein derivatives
Examples:
-Ovoglobulin (eggwhite),
-Edestin (hempseed),
-Legumin (peas)
-Myosinogen (muscles)
-Serum globulin (blood)
GLOBULINS
NUCLEO / GLYCO:
Products from glandular tissues
NUCLEO
PHOSPHO / CHROMO:
Vitellin (egg yolk)
PHOSPHO
LIPO / METALLO:
zinc–alcohol dehydrogenase (enzyme in alcohol
oxidation)
METALLOPROTEINS
Soluble in water, precipitated by conc.HNO3 and by half saturation with (NH4)2SO4 or ZnSO4
PRIMARY PROTEOSES
Examples:
-Glutenin (wheat)
-Oryzenin (rice)
GLUTELINS
NUCLEO / GLYCO:
Germ of grains
NUCLEO
PHOSPHO / CHROMO:
Hemoglobin (blood -carrier of O2 in blood )
CHROMOPROTEINS / HEMOPROTEINS
EXAMPLES OF CONJUGATED PROTEINS
Primary Protein derivatives
Secondary Protein derivatives
Precipitated only by complete saturation with (NH4)2SO4 but not with picric acid and HNO3
SECONDARY PROTEOSES
Examples:
-Gliadin (wheat)
-Zein (corn)
-Hordein (barley)
PROLAMINES
NUCLEO / GLYCO:
more proteins less carbohydrates
GLYCO
PHOSPHO / CHROMO:
Myoglobin (oxygen binder in muscles)
CHROMO
proteins which have undergone slight intramolecular rearrangement through the hydrolytic action of certain physical and chemical agents
Primary Protein derivatives
Not precipitated by saturation with (NH4)2SO4 but by certain alkaloidal reagents, such as,phosphotingstic and tannic acids
PEPTONES
Examples:
-Thymus histones
-Scobrone of Mackerel
HISTONES
NUCLEO / GLYCO:
Mucin aka mucoproteins – more carbs less proteins (saliva, mucous secretion of the nose)
GLYCO
PHOSPHO / CHROMO:
Cytochromes
CHROMO
synonymous w/ denatured proteins
Primary Protein derivatives
Are combinations of two or more amino acids, the carboxyl group of one being united with the amino group of the other
PEPTIDES
