What are Proteins?
Insulin & membrane channels, polypeptides
5
New cards
What is Nucleic acid?
DNA - nucleotides
6
New cards
Overall function of biochemical groups
work together to ensure that body cells have access to glucose for their energy needs
7
New cards
Monosaccharides (carbohydrate)
Glucose, Galactose, fructose, ribose
8
New cards
Disaccharides (carbohydrates)
Maltose, lactose, sucrose
9
New cards
Polysaccharides (carbohydrates)
Starch, glycogen, cellulose
10
New cards
proteins
enzymes, antibodies, peptide hormones
11
New cards
Triglycerides (lipids)
Fat stored in adipose cells
12
New cards
Phospholipids (lipids)
lipids forming a bilayer in cell membrane
13
New cards
Steroids (lipids)
Some hormones
14
New cards
nucleic acids
DNA, RNA, ATP
15
New cards
What do their interactions mean?
all interaction are referred to as metabolism
16
New cards
\
What is metabolisms main goal?
The main goal of metabolism is to convert food into energy and essential molecules needed for the body's growth, maintenance, and functioning.
17
New cards
Hydrolysis
Hydrolysis is a chemical reaction that involves the breaking of a covalent bond in a molecule using water as a reactant.
18
New cards
Galactose + Glucose
Lactose
19
New cards
Starch + water
Glucose
20
New cards
3 fatty acids + glycerol
Triglyceride lipid
21
New cards
Protein + water
Amino acid
22
New cards
\
What is catabolism
Catabolism is the process by which complex molecules are broken down into simpler ones, releasing energy in the process.
23
New cards
what is anabolism
Anabolism is the set of metabolic pathways that build larger molecules from smaller ones, requiring energy. It is the process by which cells synthesize complex molecules like proteins, carbohydrates, and lipids, promoting growth and maintenance of body tissues.
24
New cards
what are polar bonds
Covalent bond between oxygen and hydrogen of a single water molecule refers to a polar covalent bond
25
New cards
Which biochemical group is polar?
Carbohydrates, proteins and nucleic acid are polar molecules
26
New cards
Monosaccharides
monormer units of carbohydrates and building blocks of disaccharides
27
New cards
trioses (monosaccharides)
containing 3 carbon atoms
28
New cards
Pentose (monosaccharides)
containing 5 carbon atoms
29
New cards
hexoses (monosaccharides)
containing 6 carbon atoms
30
New cards
3 sugars
glucose, galactose, fructose
31
New cards
Glucose + glucose
Maltose
32
New cards
Glucose + fructose
Sucrose
33
New cards
Galactose + glucose
lactose
34
New cards
cellulose
major components of plant cell walls, protection, roots, stems and leaves. Can digest.
35
New cards
Glycogen
Animals store glucose in this form, glycogen is stored in the liver and in muscle tissue
36
New cards
Subcomponents of Starch
Amylopectin and amylase
37
New cards
why do animals store amylopectin
because its soluble
38
New cards
How to tell if something consists of glucose
Add Benedict and heat the solution. color changes from blue to dark orange
39
New cards
saturated fatty acid
solid at room temp and is straight due to no double bond between the C atoms making shape of molecule straight
40
New cards
Mono-saturated fatty acid
has double bond in chain making it bend.
41
New cards
polyunsaturated
has double double bond in structure, liquid at room temperature (twists)
42
New cards
What are Cis fatty acids
Cis fatty acids are a type of unsaturated fatty acids where the hydrogen atoms are on the same side of the carbon-carbon double bond. This results in a bent or "cis" configuration in the molecule. Cis fatty acids are commonly found in natural fats and oils and are typically liquid at room temperature.
43
New cards
What are Trans fatty acids
Trans fatty acids, also known as trans fats, are a type of unsaturated fat that have been chemically altered through a process called hydrogenation. This process converts liquid oils into solid fats, making them more stable and increasing their shelf life. Trans fats are commonly found in processed foods, such as fried foods, baked goods, and margarine.
44
New cards
energy storage in humans
* storing triglyceride lipids within adipose cells
* lipids have twice the energy than proteins and carbohydrates
* stored glucose as polysaccharides (glycogen) in liver and muscle tissue
45
New cards
What are lipids?
Long-term energy storage molecules, insoluble in water so they don’t upset osmotic balance of solutions
46
New cards
how to tell if something consists of lipids
add sudan as an indicator , color changes from yellow-orange to red
47
New cards
characteristics of proteins
made of amino acids

20 different amino acids

production for proteins are endless

metabolism can change amino acids into other

nitrogen needed to devolpe proteins

chain will fold up

dont like water

linked together by condensation
48
New cards
how to tell if something has proteins
