classified into
a. Albumins.
b. Globulins.
c. Glutelins.
d. Protamins.
e. Histones.
f. Prolamines.
g. Sclero proteins.
a. Albumins:Are those proteins that are soluble in water as well as salt solutions. Egg albumin, plasma albumin and lactalbumin are examples.
b. Globulins: Are proteins weakly soluble in water but soluble in salt solutions.
Ovoglobulins, plasma globulin and lactoglobulins are examples.
c. Glutelins: Are proteins soluble in mild acids and alkalis. zein, glutenin and oryzenin are examples.
d. Protamines: Are proteins soluble in water and ammonia. Fish proteins like salmine and sturine are examples.
e. Histones: Are those proteins which are soluble in water and dilute acids. Histones present in chromosomes are examples.
f. Prolamines:Are proteins insoluble in water and alcohol but soluble in dilute alcohol.
Plant proteins zein and gliadin are examples.
g. Sclero Proteins: Are proteins insoluble in water, acids and alkalis. Animal proteins keratin, elastin and collagen are examples.
