BIOLOGICAL MOLECULES Flashcards
WHAT ARE ORGANIC COMPOUNDS
compounds that come from living things, are easily decomposed and contain carbon. e.g sugar
WHAT ARE INORGANIC COMPOUNDS
compounds that come from the earth, difficult to decompose and don’t contain carbon. e.g salt, water
3 CLASSES OF CARBOHYDRATES
monosaccharides, disaccharides and polysaccharides
WHAT DO PROTEINS DO
break down amino acids and contain C,H,N,O,S and are joined by peptide bonds.
WHAT ARE ENZYMES
special proteins that speed up biological reactions, form muscle and produce hormones(insulin)
WHAT ARE LIPIDS
lipids are fats that contain C,H and O and are hydrophobic(water hating). Store energy
WHAT ARE 4 FATS
fats and acids, waxes, phospholipids and steroids
WHAT IS NUCLEIC ACID
nucleotides. Contain DNA, RNA and ribonucleic acid. Determine what proteins are made
WHAT TWO GROUPS OF VITAMINS ARE THERE
Fat soluble= D,E,A,K and water soluble= Vitamin B and C groups.
WHAT ARE IMPORTANT MINERALS FOR BODY FUNCTION
sodium, potassium, calcium, iron, phopherus and iodine
WHAT ARE CHEMICAL REACTIONS
reactants are substances that take part in the chemical reaction. Products are the new substances produced as a consequence of the reaction. e.g Na+Cl= NaCl
WHAT ARE COMBINATION REACTIONS
two or more substances combine together to make one substance
WHAT ARE DECOMPOSITION REACTIONS
when one substance is broken into 2 substances.
WHAT IS IONISATION
A decomposition
WHAT IS DISPLACEMENT
the swapping of a less reactive element for a more reactive element. e.g AB+C= AC+B
