proteins Flashcards
what are proteins
the main component in animal tissue
how are proteins formed
from the condensation reaction of many amino acids
what are essential amino acids
amino acids that cant be produced in the body and must be taken in through the diet
what are the 2 amino acid functional groups
amine (NH2) and carboxyl (COOH)
how do amino acids join together
the amine group of one amino acids joins onto the carboxyl group of another to make a peptide link
what is a peptide link
H O
N - C
(CONH)
||
how does our body break down proteins into amino acids
enzyme hydrolysis
what are enzymes
proteins which act as bio catalysts
how are amino acids transported through body
in bloodstream
how can you identify amino acids
- hydrolyse the protein to produce amino acids
- use chromatography to identify amino acids present
what is chromatography
a technique used to separate mixtures
unknown mixtures are compared against the standard and the other parts can be identified
what can proteins form
spirals, sheets and other complex shapes
how are long protein chains held in shape
intermolecular bonding
how does cooking food with protein in them work
it breaks the intermolecular bonds causing the protein to denature and change shape
