Do subscribe to Ekeeda Channel and press bell icon to get updates about latest engineering HSC and IIT JEE main and advanced videos Proteins are basically of two pairs simple proteins and conjugate proteins now simple proteins are basically made up of amino acids an example of this would be histone proteins Histone is a protein on which your DNA or double-stranded DNA is wrapped around and is kept inside a set the next type of protein is conjugate protein and I say conjugate it a complex it means mixture of two different things conjugate protein is basically made up of a protein part that is an amino acid plus a non protein part that is a prosthetic group and in say prosthetic group it means a helping an example of conjugate proteins would be lipoproteins or nuclear proteins now conjugate proteins are further divided into four different types of proteins and those four different types of proteins are structural proteins structural protein an example could be keratin that is present inside head-on the protein from which your hair is made yes the same keratin that gives a shiny texture to your hair the next type of protein is defense a protein an example of defensive protein would be antibodies immunoglobulins fighter cells all those human cells of our body that fight whenever an infection gains entry into your body are nothing but defensive protein and that top most would be antibodies IgG IgA and pigments against and body means against organism next type of protein is transport protein and classy example of transport proteins would be hemoglobin by H now been able you take an oxygen inside your body this oxygen cannot travel all what happens is your RBC’s are present upon the artisans there is a molecule called as hemoglobin which sets on the our bases and upon hemoglobin oxygen sets this three together in a tribe travel wherever they have to travel and oxygen is strong at that place where oxygen is required and RBC’s and hemoglobin get back to their position so basically hemoglobin is a transport protein for oxygen the last type of protein is contractile protein when I say contraction and relaxation this all is associated with your muscles or moment now myosin is a protein that is present inside muscles which helps in relaxation and contraction of your muscles types of proteins are simple protein and complex proteins simple proteins are made up of amino acids for an example of this is histone proteins on which DNA is wrapped the next type of protein is conjugate protein or even sick complex proteins or combination proteins now this conjugate proteins are made up of two protein as well as non protein part the protein part is basically amino acid and the non protein part is prosthetic group or helping hand now this a minus a plus through trust a table together forms the viable protein an example of this this proteins plus lipids that forms lipoproteins and this lipoproteins are nothing but helps in signaling or inside or outside entry or exit of biomolecules inside set types of conjugate proteins are structural proteins transfer proteins defensive proteins and contractile proteins an example of structural protein is keratin that is present inside cell transfer proteins made include HP or hemoglobin that help to transport oxygen along with RBC’s their trial travels together for oxygen supply in body another type of protein is defense a protein an example of this is antibodies or AV or immunoglobulins now this antibody protect human beings against infections of certain diseases the last type of proteins are contractile proteins contact eye proteins an example of this is myosin that is present inside muscle which hits in contraction and relaxation of muscles so students in this part of the chapter we have studied about various types of proteins and how they function together I hope you all are clear about various types of proteins and their function thank you
