Baby need more energy per unit body weight
because
The relative surface area of baby is large, they need more energy to
produce heat to compensate heat loss
DCPIP test

Peter: Weight:50kg, Daily energy requirements: 11500 kJ
Calculate Peter’s daily energy requirement per unit body weight (kJ/kg)?
11500/50 = 230 kJ/kg
Vitamin C
Food test
DCPIP test
Glucose
Function
Produce energy by respiration
Reducing sugar
Food test
Benedict’s test
What is the fate of excess protein?
Excess amino acids cannot stored and will be broken down in liver by deamination :(i) Urea formed is carried via the bloodstream to the kidneys and is excreted in the urine.(ii) The remaining part of the amino acid is converted to glycogen and stored in liver.
Benedict’s test
Positive result

Albustix paper
Iodine test
Positive result
Brown to blue black
Protein
Functions
Growth and repair, produce enzyme, hormone,
haemoglobin
Lipid
Function
Produce energy, shock absorber, heat insulator
Calcium
Function
Form bones and teeth
Water
Function
As solvent, for transport, heat loss by sweating
Vitamin A
Deficiency disease
Night blindness
What is the fate of excess glucose?
Excess glucose is converted to glycogen by the liver for
storage. Some of the excess glucose is converted to
lipid.
