Biochemistry- Protein Structure

Proteins – linear polymers of amino acids – peptide bond formation enables protein formation Size of a protein 50 to >30 000 amino acids Protein Formation: 1. Condensation reaction 2. Covalent bond (shares electrons) 3. No rotation around the bond 4. Atoms are co-planar 5. Restricts the possible folding patterns of the chain Polypeptides – […]

TONICITY – BIOCHEMISTRY

Osmosis – movement of water molecules from an area where there is more H2O -> less water through a selectively permeable membrane Isotonic Solution – same amount of solute as that found inside the cell – water moves in and out at equal rate Animal Cell Isotonic – no change in cell Plant Cell Isotonic […]

Chapter 3 Section 2: Biochemistry-Review

Compare the structure of monosaccharides, disaccharides, and polysaccharides. A monosaccharide is a monomer of carbohydrates. 2 monosaccharides can combine to form a double sugar, or a disaccharide. A polysaccharide is a complex molecule composed of 3 or more monosaccharides. How are proteins constructed from amino acids? Amino acids link together to to form proteins. How […]
