B1.1 (mostly carbohydrates) Flashcards
molecule
particle of +2 (?atom?)
organic contains
H and o2
proteins contain
C H O N
and sometimes sulfur
molecular acid elements
P N C H O
lipids contain
C H(more than o) O
carbohydrates
c h o
we need.. for bodys function
vitamins and minerals which have elements in them
covalent bond
between 2 non metals, they are stable, share an electon
carbon can creat
4 covalent bonds
example of
chain
ring
branch of carbon
sugar photsphate
dna base
Butane
polymers vs monomers
large molecules made of REPEATING SUB UNITS (polysaccharides and proteins)
smaller sub units that can join together
amino group
…..H
R - n
H
methyl group
…-h
R-c-h
-h
Carboxyl
O=
C
-oh
hydroxyl
O
R H
disaccharodes
maltose sucroes lactose
*a double sugar formed when two monosaccharides are joined via dehydration synthesis.
brain only respires
com glucose ,
which is stable, soluble, and releases energy woth o2 and produces a lot
is the only carbohydrate dependant organ
its cells receive 2x the amout of any other
in hexose and pentose sugar elements
hexose: c6 h12 o6 (glucose, galactose, fructose ) ——-all same elements but diffrent arrangements
pentose c5 h10 c5 (ribose and deoxyribose)
1:2:1 ratio
consensation
hydrolysis
forming bigger, produces h2o
breaking apart
glycoproteins roles
cell-cell recognition
receptors
ligland
structural support
cell-cell recognition
mark surface of cells to identify properlyy
receptors
receptors on cell surface recive signals from other cells or molecules in the enviroment
ligland
bind to specific cells to initiate signalling pathways
structural support
help structural integroty of cells and tissues
can form matrix to support cells
