How many types of proteins?
millions coded for by 3500ish genes
Some other types of proteins are enzymes, haemoglobin, antibodies, plasma casein in milk, eeg albumin and the albumins and globulins of blood. The five types of proteins are structural, storage, hormonal, enzyme, and immunoglobulins. All proteins are complex molecules and structural proteins make up the largest class of proteins.
Considering the human body has an astronomical amount of protein types and each protein type has an astronomical number of individual proteins, pin-pointing a number is worthless. Your body creates and loses proteins constantly. There are only 4 major types for DNA: adenine, cytosine, guanine and thymine. As for a # of proteins as a whole: A whole bunch.
There are many functions of proteins. They are the basic building blocks of living things and are responsible for the growth and repair of body cells and tissues. The human body is about one half muscle, and muscles are mostly made of proteins. There are seven main types of protein: antibodies, contractile proteins, enzymes, hormonal proteins, storage proteins, structural proteins, and transport proteins.
There are different class of proteins but the majority is structural proteins such as actin, myosin that build up our and many different functional proteins. APOBEC is a class of deaminases that catalyse the deamination of viral DNA (cytidines) during their infection (SIV, HIV). Hemoglobin carries oxygen to all the cell types. Other enzymes does activity in metabolism of biomolecules.
