Proteins Classification
Proteins are classified into three groups: (A) simple proteins (B) conjugated proteins and (C) derived proteins.
A. Simple proteins: on hydrolysis they yield only amino acids.
(i) Albumins: they are soluble in water and are heat coagulable. They can be precipitated form solution by saturating the solution with ammonium sulphate. Egg albumin serum albumin lactalbuin form milk and soya bean albumin are some examples.
(ii) Globulins: they are insoluble in water but soluble in dilute salt solutions. Like albumins they are also heat coagtulable. They are precipitated form solution by half saturation with ammonium sulphate. They occur together with albumins in the same sources such as milk egg and serum.
(iii) Glutelins: they are soluble in dilute acids and alkalies but insoluble in neutral solvents. The proteins of wheat, rice and other corals belong to this group.
(iv) Polyamines: they are soluble in 70% alcohol. They are rich in praline and occur in creels like corn barley and other.
(v) Scleroproteins (albuminoids): they re insoluble in all the solvents considered do far. They are animal proteins present in hare horn hoof nails cartilage and bone collagen of bone keratin go hair and fibroin of silk are a few examples. They are in general rich in sulfur containing amino acids.
(vi) Histones: they are soluble in water dilute acids and salt solutions. They have isoelectric pH on the alkaline side because they contain large amounts of basic amino acids liekarginine. The globin of hemoglobin and the rote in moiety of several nucleoproteins belong to this group. They can form salt like compounds with acidic substances eg. Nucleic acids.
(vii) Protamines: these are the simplest of the proteins with very low molecular weights. They are strongly basic and are rich in arginine. They occur in the nucleoproteins of the sperm
Histones and Protamines since they normally occur in conjugated proteins like hemoglobin and nucleoproteins may also be classed under derived proteins.
B. Conjugated proteins
The proteins in this group are combined with a non- protein group called the prosthetic group.
(i) Nucleoproteins
(ii) Glycorporateins
C. Derived proteins
They are products of Denaturation or of partial digestion of proteins.
(i) Proteins: these are denatured proteins fibrin form fibrinogen myosin form myosin.
(ii) Met protein: on treatment with acid ro alkali the corresponding acid or alkali met protein is formed.
(iii) Coagulated proteins: they are also denatured proteins.
All the above three groups are called the primary derived proteins those produced as a result of partial digestion are called secondary derived proteins (iv) proteases; (v) peptones and (vi) peptides are fumed in that order when a protein Is hydrolyzed in a stepwise manner. The molecular size diminishes gradually but the polypeptide structure and protein reactions are still given by the products.
