    Study Notes

    • Proteins are organic materials commonly found in animal protoplasm and among living matter.
    • Proteins consist of carbon (C), hydrogen (H), oxygen (O), nitrogen (N), sulfur (S), phosphorus (PH), calcium (Ca), and other elements.
    • Protein molecules are complex, made up of amino acids as their simplest structural units.
    • Amino acids are the main building blocks of proteins and peptides, consisting of an amine group (-NH2) and a carboxyl group (-COOH).
    • Essential amino acids (valine, leucine, tryptophan) cannot be produced by the body and must be obtained through food.
    • Semi-essential amino acids (histidine, arginine) can be produced by the body but in insufficient quantities.
    • Non-essential amino acids make up the rest of the amino acids.
    • Simple proteins decompose into three types: histones (main component of chromosomes, dissolve in water but not diluted ammonia), albumins (dissolve in water, coagulate with heat, found in blood serum), and globulins (soluble in acids, alkalis, and salt solutions but not water, produced in the liver by the immune system).
    • Protamine dissolves in water but does not coagulate with heat, plays a significant role in transferring genetic characteristics and regulating biological reactions.
    • Conjugated proteins involve simple proteins combined with other substances, with three types: glycoproteins (proteins bound with carbohydrates), nucleoproteins (proteins united with nucleic acid), and lipoproteins (proteins combined with fat).
    • Derived proteins are complex proteins that undergo partial degradation, including proteoses, peptones, and proteases.
