Glutamic acid is a naturally occurring α−amino that contains a carboxy group in its r group side chain. (glutamic acid is drawn in its neutral form with no charged atoms, a form that does not actually exist at any ph.) if the ph is gradually increased, what form of glutamic acid exists after one equivalent of base is added to the positively charged form? after two equivalents? after three equivalents?

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
