Biochemistry (anatomy)

biochemistry the chemical composition of living matter macromolecules composed of long chains of building blocks called monomers organic compounds carbon-containing compounds carbon the backbone of all chemical compounds; when burned turns black, can bond as many as 4 atoms carbohydrates include sugars and starches, main source of energy for all living things, structural component for […]

Biochemistry- Protein Function

What are the 6 classes of proteins and the location/function of proteins in each? 1) Structural- hair, cell cytoskeleton 2) Contractile- muscle, motile cells 3) Defense- antibodies, membranes proteins 4) Transport- hemoglobin, membrane proteins 5) Signalling- hormones 6) Enzymatic- regulate the speed of a biochemical reaction (yeah, I know it’s weirdly different. The lists are […]

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 […]
