BIOMOLECULES :smiley:
NUCLEIC ACIDS
-
-
-
DNA
-
has two polynucleotides spiraling around an imaginary axis, forming a double helix
-
-
PROTEINS
functions: defense, storage, transport, cellular communication, movement, and structural support
enzymatic proteins: selective acceleration of chemical reactions
defensive proteins: protection against disease
storage proteins: storage of amino acids
transport proteins: transpOrt of substances
hormonal proteins: coordination of an organism's activities
receptor proteins: response of cell to chemical stimuli
contractive and motor proteins: movement
structural proteins: support
-
structure factors
alterations in pH, salt concentration, temperature, or other environmental factors can cause a protein to unravel
amino acid sequence, physical, and chemical conditions
denaturation: loss of a protein's native structure, causing the protein to be biologically inactive
biologically functional molecules consisting of one or more twisted, folded, and coiled polypeptides of a unique shape
CARBOHYDRATES
-
types
monosaccharides: simplest carbs (simple sugars), which are used as major nutrients for cells and as raw material for building molecules
carbohydrate macromolecules are polysaccharides, which are polymers composed of many sugar building blocks
storage polysaccharides: starch (plants) and glycogen (animals)
structural polysaccharides: cellulose (plants)
