22
What type of bond is found between amino acids
Peptide bond
Primary Structure of Amino acids
Sequence of amino acids in the polypeptide chain
Secondary Structure of Amino acids
Hydrogen bonding with adjacent amino acids
Tertiary structure of Amino acids
Folding of the polypeptide chain to the interaction of the R groups.
Quaternary structure of amino acids
Interaction of 2 or more polypeptide globules
Necklace
Primary
Helical or pleated shape
Secondary
3 dimensional shape with unique surfaces and pockets
Quaternary
Antibodies for immune system
Proteins
Forming bone and teeth, conducting nerve signals, balancing bodily fluids, normally in the form of chemical elements
Minerals
Water
Transports dissolved nutrients into the cells lining the small intestine, lubricates tissue and joints.
