Nutrients from breast milk.
Explanation:
Healthy newborns make blood glucose from sugar and several nutrients from the colostrum, a type of liquid that mother’s breasts produce before breast milk itself. Later, the babies make glucose from mature breast milk.
Most healthy babies, born after 37 weeks of gestation do not risk hepatic glycogen drops. They can easily compensate for normal drops in blood sugar, in other words, whenever the baby is breastfed when needed, he/she will be able to keep his/her glucose levels stable.
Functional groups are a group of molecules attached to a carbon-based core of an organic molecule. Key functional groups are 3. phosphates
The only exception would be nuclear energy. Heavy elements like Uranium got their stored energy from ancient supernovae, that doesn't come from the sun. And fusing hydrogen is tapping energy that has been around since the Big Bang.
Hope this helped :)
