Amino Acid + Amino Acid + Amino Acid -> Protien (What holds amino acids together?)?

Answer 1

peptide bonds between nitrogen and carbon of another amino acid

Answer 2

two amino acids are joined by a dehydration (aka condensation) reaction resulting in the net loss of a water molecule and the formation of a new amide (peptide) bond between the two amino acids

Answer 3

Because textbooks are incomplete, like these answers. Peptide bonds connect peptides, but that's insufficient for 3D structure of proteins. Also disulfide bonds between cystines are critical, and hydrophobic interactions, and van der walls forces. There's more to protein structure than the peptide bond.

Answer 4

There ya go champ: http://www.rothamsted.ac.uk/notebook/courses/guide/images/pept.gif

Peptide bonds (covalent bonding here) hold amino acids together. This bond is formed from a dehydration synthesis, a form of elimination reaction (in this case, elimination of water...H2O). The hydroxyl group (OH-) is a poor leaving group, but protonation by the NH2, forms a better leaving group (in this case: -OH2+).

Answer 5

wouldn't it have been faster to look it up in a textbook or wikipedia. Anyway as everyone has probably said peptite bonds is the answer

Answer 6

peptide bonds

Answer 7

peptide bonds
