artificial addition of hydrogen atoms to an unsaturated fat in order to make the fat more
saturated
trans fats
created from hydrogenation
do all lipids/fats store energy
no
sterols
plays important role in regulating growth & development (includes cholesterol,
testosterone, and estrogen)
cholesterol
important component of most cell membranes (essential molecule for living organism),
can cause health problems though
steroid hormones
regulates sexual development, maturation & sex cell production
estrogen-memory&mood
testosterone-stimulates muscle growth
phospholipids
major components of the membrane that surrounds the contents of a cell & controls flow
of chemicals in & out of the cell, structure is similar to fats
waxes
resemble fats but have only one long-chain fatty acid lined to the glycerol head of the
molecule, highly non polar, strongly hydrophobic
proteins
chief building block of all life
functions - make up muscles & components of bone, stops bleeding, controls sugar
levels and carries oxygen
protein diversity
structure, protection, regulation, contraction, transportation (SPRCT)
enzymes
initiate & assist every chemical reaction that occurs, help initiate and accelerate
chemical reactions in our bodies, they emerge in original state after reaction is complete
amino acids
20 molecules of protein
containing - carbon, hydrogen, oxygen, nitrogen, carbon atom at centre with four carbon
bonds
essential because? growth & repair, replacement, good for building projects
ideal protein per day
40-80
