What is the charge of a Peptide with sequence aggdrleeq at pH 7.0?
At a neutral pH i.e. pH 7, only five of the twenty common amino acids carry a net positive or a net negative charge. Aspartic acid and Glutamic acid are negatively charged (-1), at a neutral pH the carboxlic side chains lose a H+ ion Lysine, Arginine and Histidine are positively charged (+1), at a neutral pH the side chains accept a H+ ion. All other amino acids are generally uncharged (0). It is therefore easy to work out the net charge of any sequence. All sequences contain the one letter abbreviation for each amino acid. Here the sequence is "aggdrleeq" a=alanine (uncharged = 0) g=glycine (uncharged = 0) g=glycine (uncharged = 0) d=aspartic acid (negatively charged = -1) r=arginine (positively charged = +1) l=leucine (uncharged = 0) e=glutamic acid (charged = -1) e=glutamic acid (charged = -1) q=glutamine (uncharged = 0) Add up all the charges -3, +1 gives a total peptide charge of -2.

2.Positively charged objects can only attract objects that are negatively charged?
Any charged object weather positively charged or negatively charged will have an attractive interaction with a neutral object. Neutral objects do not attract or repel each other.
Which term describes the particle that results when an electron is added to an atom?
It depends. If you are talking about electron capture at the molecular level, then when a neutral atom (or molecule) absorbs a negatively charged electron, it becomes negatively charged. All charged atoms (or molecules) are called ions, and a negatively charged ion is called an anion. . If, on the other hand, you are talking about electron capture by the nucleus of an atom, then when a positively charged proton absorbs a negatively charged electron, the proton converts into a neutrally charged neutron and immediately emits a neutrally charged electron neutrino.
What is something with a negatively charged particle?
Things that contain negatively charged particles include atoms, protons, neutrons, as well as any molecules, and larger, everyday, objects.
Are neutral attracted to or repelled by positively and negatively charged objects?
Any interaction occur.
Is carbon postively charged?
No. Any element on its own is neutral, meaning it does not have a charge. Carbon rarely forms ions, and when it does they are negatively charged.
What carry a what electrical charge?
Electrons are negatively charged. (The positron is a positively charged version). Protons are positively charged, so an anti-proton would carry a negative charge. Any object that has, on average surplus electrons in the outer-shells of electron orbitals will appear negatively charged.
What is cation and anion?
Cations are positively charged ions. Anions are negatively charged ions. An ion is just an atom with either more electrons than protons (so it would be negatively charged... an anion), or fewer electrons than protons (so it would be positively charged... a cation). It should be noted that not all ions are single atoms. You can have polyatomic (many atom) anions (like SO42-) or cations (like NH4+). These are just molecular compounds that have charge because they have gained or lost electrons.
What is a negatively charged matter?
Any material can be charged, either positively or negatively. It has no name as such. You can do that by shuffling your feet back and forth on a carpet and touching something. You can feel a spark from your finger. By shuffling your feet your body acquires a charge, which discharges when you touch a metal object that is grounded.
Who would have viewed the pax romana negatively?
No one in the days of the Pax Romans would have viewed it either positively or negatively because it is a term which has been coined by historians. The Romans did not use this term or any of the concepts which are related to this term.
When a glass rod and fur rubbed together electrons are transferred from the fur to rod. Is the fur charged If any positively or negatively charged How much compared to the rod?
Yes , if elctron goes from fur to rod, fur is positively charged
What characterstic is the same for all atoms of any elements?
all will have a positively charged nucleus with negatively charged electrons revolving around it. all will also have neutrons in the nucleus (except for 1H1 isotope)
If some amount of positive charge is given to a soap bubble what will happen to it?
It will be attracted to any negatively charged objects and repelled by any positively charged objects. It will probably be mildly attracted by neutral objects but this would be a much smaller effect.
