PROTEINS

  1. Protein was discovered by Mulder.
  2. Berzilius gave the catalytic concept & gave the word protein, which means first rank.
  3. Protein holds the 1st place in body.
  4. Proteins are consists of C > O > N > H > S
  5. Proteins are macromolecules (polymer of amino acids).
  6. Only 20 amino acids participates in the formation of proteins.
  7. Proteins are large-sized mixed polymers of L- amino acids joined by peptide linkage.
  8. The macromolecules are formed of C,H,O, N and in many cases S, Fe, Cu and P element may present.
  9. Quantity of protein is different in different parts - Cow's milk - 3.5%, Blood plasma - 7%, Egg white - 11.3%, Cereals - 12%, Egg yellow - 15-17%, Pulses - 20%, Muscles - 20%, Chick's flesh - 24%, Glicenmax - 60%, Chlorella - 85%
  10. Maximum complicated.
