Tools

A	B
ninhydrin	amino acids test
charring or burning	carbon test
cobalt chloride	water test
Benedict's solution	sugar test
biuret solution	protein test
sudan III or IV	lipid test
iodine	starch test
all biomass contains	water at some time, amino acids, carbon
sugar or starch present	plant
protein and fat present	animal biomass, nuts
starch or protein present, water is not obvious	seed
leaves vs. roots?	more starch in roots
pH of most biomass	near neutral
positive amino acids test results	violet stain appears
positive water test results	paper turns from blue to pink
positive sugar test results	color turns from blue to red, orange or yellow
positive protein test results	color turns from blue to violet
positive starch test results	color turns from orange to blue-black
positive carbon test results	charring of biomass occurs
