What are the proteins? Proteins are the linear, unbranched polymers of amino acids which are held together by peptide bonds. There are about 20 amino acids that are used in synthesising all types fo proteins. The sequence of these amino acids is specific for a particular polypeptide and it helps in determining the nature of proteins. The protein molecules are large, complex and have high molecular weight. The minimum molecular weight of a protein is that of adrenocorticotrophin hormone i.e. 4500. Protein is not freely soluble in water but forms the colloidal solution with the same. They may be formed … Continue reading Proteins- Simple and Conjugated proteins
