Document Summary
Transport (e. g. : hemoglobin- transports o2 in the blood) Genome- all of the genes coded in a cell"s dna. Proteome- complete protein complement expressed by a cell. Protein (polypeptide)- molecules that contain >50 amino acids. The - carbon always has 4 substituents and is tetrahedral. An acidic carboxyl group, a basic amino group, an - hydrogen and a r group. There are 8 essential amino acids (that our bodies can not synthesize) 7 have aliphatic r groups (glycine, alanine, proline, valine, leucine, isoleucine, methionine) 3 have aromatic r groups (phenylalanine, tyrosine, tryptophan) 5 have polar uncharged r groups (serine, threonine, cysteine, asparagine, glutamine) 3 have positively charged (basic) r groups (lysine, arginine, histidine) 2 have negatively charged (acidic) r groups (aspartate, glutamate) With acidic ph, the carboxyl group is protonated, and the amino group is cationic. With alkaline ph, the amino group is neutral and the amino acid is anionic.
