Define secondary structure
The compact structure of a protein molecule resulting from the three-dimensional coiling of the already-folded chain of amino acids
The structure of a protein molecule resulting from the regular coiling or folding of the chain of amino acids, e.g an alpha helix or beta pleated sheet.
The three-dimensional arrangement of two or more polypeptides, or of a polypeptide and a non-protein component such as haem, in a protein molecule
The sequence of amino acids in a polypeptide or protein
whats the function of a phospholipid ?
Water is the transport medium in the blood, in the lymphatic, excretory and digestive systems of animals, and in the vascular tissues of plants
The structure of a protein molecule resulting from the regular coiling or folding of the chain of amino acids, e.g an alpha helix or beta pleated sheet.
Each molecule has the unusual property of having one end which is soluble in water. This is because one of the three fatty acid molecules is replaced by a phosphate group, which is polar and can therefore dissolve in water.
Define tertiary structure
The compact structure of a protein molecule resulting from the three-dimensional coiling of the already-folded chain of amino acids
The three-dimensional arrangement of two or more polypeptides, or of a polypeptide and a non-protein component such as haem, in a protein molecule
The structure of a protein molecule resulting from the regular coiling or folding of the chain of amino acids, e.g an alpha helix or beta pleated sheet.
Each molecules has the unusual property of having one end which is soluble in water. This is because one of the three fatty acid molecules is replaced by a phosphate group, which is polar and can therefore dissolve in water.
Define primary structure
The three-dimensional arrangement of two or more polypeptides, or of a polypeptide and a non-protein component such as haem, in a protein molecule
the chemical breakdown of a compound due to reaction with water.
The structure of a protein molecule resulting from the regular coiling or folding of the chain of amino acids, e.g an alpha helix or beta pleated sheet.
The sequence of amino acids in a polypeptide or protein
Define Quaternary structure
The sequence of amino acids in a polypeptide or protein
The structure of a protein molecule resulting from the regular coiling or folding of the chain of amino acids, e.g an alpha helix or beta pleated sheet.
The three-dimensional arrangement of two or more polypeptides, or of a polypeptide and a non-protein component such as haem, in a protein molecule
The compact structure of a protein molecule resulting from the three-dimensional coiling of the already-folded chain of amino acids
Molecules which have groups with dipoles, such as sugars, are said to be
hydrogen bond
non polar
covalent bond
polar
When atoms in molecules are held together by BLANK, they share electrons with each other.
covalent bonds
peptide bonds
hydrogen bonds
phospholipids
Difference between haemoglobin and collagen
To ensure that all of the sugar reacts with the Benedict's reagent
The oxygen carrying pigments haemoglobin and myoglobin are proteins
Haemoglobin is a globular protein meaning its 3D feature is to roll up into balls, yet collagen is a fibrous protein so its 3D feature is to form fibres.
Each folded protein contains a Haem group which binds to oxygen. The major function of hemoglobin is to transport oxygen from the lungs to the body's tissues and then transport carbon dioxide out of the tissue back to the lungs.
