biology enzymes nutrients Flashcards
what orangic molecule are carbo made of
carbon, hydrogen, nitrogen
general formula of cabo
Cn, H2n, Nn
function of carbo
provide energy, provide support, covert organic compound, form nucleic acid
list the single sugar
glucose, fructose, galactose
list the double sugar
sucrose, maltose, lactose
list the complex sugar
cellulose, starch, glycogen
which carbo are reducing sugar
single and double sugar
formation of carbo
glucose and glucose equal maltose
purpose of starge
storage form of carbo for plants
purpose of cellulose
main components of cell wall
purpose of glycogen
storage form of carbo for mammals
how to test for starch
add iodine solution and if blue-black starch is present but if brown no starch
how to test for reducing sugar
add same benedict solution, boil 2-3 min and observe colour change if reddish-brown present there starch
organic compound of fat
carbon, hydrogen, oxygen
functions of fats
storage of energy, insultating material, solvent, main part of cell membrane, reduce water loss
wat are fats made of
3x fatty acid and glycerol
how to test for fats
add ethanol water, shake and observe if cloud is present
organic compound or proteins
carbon, hydrogen, nitrogen, oxygen
function of proteins
synthese growth
synthesis enzymes
synthesis antibody
formation of protein
many amino acid form to polypetides then more polypetides form protein
test for proteins
add biuret solution and observe if from blue to violent protein is present (add sodium chloride then add copper sulfate drop wise)
